1 Gulf Coast Testing, LLC Model 500D Wastewater Treatment System SPECIFIC PERFORMANCE EVALUATION Under the provisions of ANSI/NSF Standard 245 (2010a) Residential Wastewater Treatment Systems SPE179 March 2013

2 EXECUTIVE SUMMARY Gulf Coast Testing, LLC conducted testing and specific performance evaluation of the Clearstream Wastewater Systems, Inc. Model 500D aerobic treatment unit under the provisions of NSF/ANSI Standard 245 (2010a) from May 27, 2012 to November 23, The test was conducted at Gulf Coast Testing s wastewater facility located in Ascension Parish, Louisiana using wastewater diverted from a lift station supplied by a residential neighborhood. The test consisted of three weeks of dosing with sampling to allow for plant start-up, sixteen weeks of dosing at design flow, seven and a half weeks of stress test and an additional two and one half weeks of dosing at design flow. Sampling started in the spring and continued until fall, covering a wide range of operating temperatures. All data collected for the specific performance evaluation was collected pursuant to ANSI/NSF Standard 245 (2010a) testing protocol. The Clearstream Wastewater Systems, Inc. Model 500D produced an effluent that successfully meets the requirements of ANSI/NSF Standard 245 (2010a). During the first month of the evaluation, the maximum 7-day arithmetic mean was 5 for CBOD 5 and 9 for suspended solids, both below the allowed maximums of 56 and 63 respectively. The 30-day arithmetic mean during the first month of testing was 4 for CBOD 5 and 8 for suspended solids, both below the allowed maximums of 35 and 42 respectively. During the final five months of the evaluation, the maximum 7-day arithmetic mean was 5 for CBOD 5 and 8 for suspended solids, both below the allowed maximum of 40 and 45 respectively. The maximum 30-day arithmetic mean was 5 for CBOD 5, below the allowed maximum of 25. The maximum 30-day arithmetic mean was 7 for suspended solids, below the allowed maximum of 30. The Clearstream Wastewater Systems, Inc. Model 500D reduced the nitrogen to 47.1 percent of its original value for an average total reduction of 52.9 percent over the entire evaluation period (excluding the stress testing results). This figure was calculated by dividing the sum of the total nitrogen effluent over the entire period by the sum of the total nitrogen influent over the entire period excluding the stress testing periods. The average percent nitrogen removed by month is shown in the table below. Over the course of the evaluation, the influent total nitrogen loading averaged lbs/day, and the Model 500D aerobic treatment unit removed lbs/day. The nitrogen data is included in Appendix C.

6 1.0 PROCESS DESCRIPTION There are two basic zones or compartments to this treatment unit. Wastewater enters the aeration chamber of the process tank, where it is mixed with organisms formed during decomposition of organic material in the wastewater, mixing in the chamber is achieved by release of compressed air near the bottom of the chamber through fine bubble diffusion. A conical shaped clarifier is located internal to the process tank to provide for separation of the solids from the mixed liquor. The mixed liquor passes into the bottom of the clarifier by hydraulic displacement as wastewater enters the aeration chamber. Solids settled from the wastewater are drawn back into the aeration chamber from the bottom of the cone by the hydraulic roll created by the air released in the aeration chamber and are dispersed by the mixing induced by the aerator. Discharge of the clarified effluent occurs through a submerged tee assembly located below the clarifier surface to prevent discharge of solids that may float on the surface of the clarifier. from the unit after exiting the clarifier enters a pump tank, the water from the pump tank is periodically discharged by a submersible pump. A portion of the discharge is returned through a flow restrictor to a pretreatment tank located in front of the treatment unit for nitrogen removal. 2.0 PERFORMANCE EVALUATION 2.1 Description of Plant Evaluated The Clearstream Wastewater System, Inc. Model 500D is a fiberglass aerobic treatment system with a rated capacity of 500 gallons per day. The Model 500D was tested using a CS-103E aerator. The plant has an alarm circuit that is activated upon loss of air pressure in the piping system, whether caused by compressor failure or a break in the air piping system. A high water sensor/alarm system is also located in the plant. Plant specifications and drawings are included in Appendix A. There are four basic zones or compartments to this treatment unit. Wastewater enters the pretreatment tank which serves to reduce the impact of oil and grease on the system and provide a zone for nitrogen removal. From the pretreatment tank the wastewater flows into the aeration chamber of the tank. There it is mixed with organisms formed during decomposition of organic material in the wastewater. Mixing in the chamber is achieved by release of compressed air near the bottom of the chamber through fine bubble diffusion. A conical shaped clarifier is located internal to the process tank to provide for separation of the solids from the mixed liquor. The mixed liquor passes into the bottom of the clarifier by hydraulic displacement as wastewater enters the aeration chamber. Solids settled from the wastewater are drawn back into the aeration chamber from the bottom of the cone by the hydraulic roll created by the air released in the aeration chamber and are 03/15/2013 SPE179 This report may not be reproduced in whole or in part 1 of 12 Final Report without the express written consent of Gulf Coast Testing, LLC

7 dispersed by the mixing induced by the aerator. Discharge of the clarified effluent occurs through a submerged tee assembly located below the clarifier surface to prevent discharge of solids that may float on the surface of the clarifier. The outlet assembly includes a gas baffle to prevent the potential entrance of rising solids in the clarifier into the outlet tee and a slotted surge control weir to reduce the impact of surge flows on the clarifier. from the clarifier enters a pump tank that uses a submersible pump to discharge the final effluent while utilizing a flow restrictor to return a portion of the effluent back to the pretreatment tank for nitrogen reduction Exposed Surfaces The exposed surfaces were evaluated pursuant to Section 5.1 of ANSI/NSF Standard 245 (2010a) and found to be in compliance Structural Integrity A structural analysis was performed to evaluate the unit pursuant to Section 5.2 of ANSI/NSF Standard 245 (2010a). The unit was determined to be structurally competent based on a structural test. An in situ visual inspection was performed both during and after the performance testing. The evaluation of the unit was found to be in compliance with this section Infiltration and Exfiltration A 24 hour infiltration and exfiltration test was performed and evaluated pursuant to Section 5.3 of ANSI/NSF Standard 245 (2010a). At the end of the 24 hour period, there was less than a 0.5% change in the initial water level of the system. 2.2 Test Protocol Startup of the plant was accomplished by filling the plant with 2/3 water and 1/3 raw sewage. The plant was then dosed at the design loading rate of 500 gpd as follows: 6 a.m. to 9 a.m. 35 percent of daily rated capacity (175 gallons) 11 a.m. to 2 p.m. 25 percent of daily rated capacity (125 gallons) 5 p.m. to 8 p.m. 40 percent of daily rated capacity (200 gallons) Dosing was accomplished by operating a pump to deliver multiple doses in five gallon increments to the test plant. Doses were spread uniformly over each dosing period. After a startup period of three weeks, the plant was subjected to the following loading sequence: 03/15/2013 SPE179 This report may not be reproduced in whole or in part 2 of 12 Final Report without the express written consent of Gulf Coast Testing, LLC

8 Design loading Stress loading Design loading 16.0 weeks 7.5 weeks 2.5 weeks During the design loading periods, flow proportioned 24-hour composite samples were collected of the influent and effluent three days per week during design loading and twice during each stress recovery period (the week following completion of each of the stress simulations described below). For ANSI/NSF Standard 245 (2010a), the effluent samples were also analyzed for alkalinity, TKN (as N), Ammonia-N (as N), and Nitrite/nitrate-N (as N). The influent samples were analyzed for Alkalinity, TKN (as N), and Ammonia-N (as N). On-site determinations of the effluent and influent temperature, ph, and dissolved oxygen were recorded. Stress testing is designed to evaluate how the plant performs under non-ideal conditions, including varied hydraulic loadings and electrical or mechanical failure. The test sequence includes: (1) Wash Day stress, (2) Working Parent stress, (3) Power/Equipment Failure stress, and (4) Vacation stress. Appendix B contains detailed descriptions of the stress sequences. During stress loading, influent and effluent 24-hour composite samples were collected on the day each stress condition was initiated. Twenty four hours after the completion of washday, working parent, and vacation stresses, influent and effluent 24-hour composite samples were collected for six (6) consecutive days. Forty eight hours after the completion of power/failure stress, influent and effluent 24-hour composite samples were collected for five (5) consecutive days. The analyses and on-site determinations completed on the samples are the same as described for the design load testing. In order for the plant to achieve Class I effluent, it is required to produce an effluent which meets the EPA guidelines for secondary effluent discharge: (1) CBOD 5: The 30-day average of effluent samples shall not exceed 25 and each 7-day average of effluent samples shall not exceed 40. (2) Suspended Solids: Each 30-day average of effluent samples shall not exceed 30 and each 7-day average of effluent samples shall not exceed 45. (3) ph: Individual effluent values remain between 6.0 and 9.0 Requirements are also specified for effluent color, odor, oily film and foam, as well as maximum noise levels allowed from the plant. 2.3 Test Chronology The system was installed under the direction of the manufacturer on May 8, 2012 and the infiltration/exfiltration test was completed May 9, The plant was dosed and R&D was performed on the plant. The plant was filled with 2/3 fresh water and 1/3 raw 03/15/2013 SPE179 This report may not be reproduced in whole or in part 3 of 12 Final Report without the express written consent of Gulf Coast Testing, LLC

Based on this assessment, specific data points may be excluded from the averages'. Rationale for all data exclusions shall be documented in the final report Catastrophic site problems In the event that a catastrophic site problem not described in the Standard including, but not limited to, influent characteristics, malfunctions of test site apparatus and acts of God, jeopardizes the validity of the performance testing, manufacturers shall be given the choice to: 3/15/13 SPE179 Appendix B 5 of 7

28 - Perform maintenance on the system, reinitiate system start-up procedures, and restart the performance testing; or - With no routine maintenance performed, have the system brought back to preexisting conditions and resume testing within 3 wks after the site problem has been identified and corrected. Data collected during the system recovery period shall be excluded from the effluent averages. NOTE -"Pre-existing conditions" shall be defined as the point when the results of 1 wk's worth of sampling are within 15% of the averages of the samples from the previous 3 wks of sampling quality For purposes of determining system performance, only samples collected during design loading periods, described in 8.2.2, shall be used in the calculations. The data collected during the stress sequences shall not be included in the calculations, but shall be included in the final report CBOD 5 The average CBOD 5 of all effluent samples shall not exceed TSS The average TSS of all effluent samples shall not exceed Total nitrogen The average total nitrogen concentration of all effluent samples shall be less than 50% of the average total nitrogen concentration of all influent samples ph The ph of individual effluent samples shall be between 6.0 and 9.0 SU. 8.5 Final report A final report shall be prepared that presents the following: - All data collected in accordance with the testing and evaluations within this Standard - A table indicating the actual percent reduction over the course of the test (included in the Executive Summary, as well as in the body, of the report) - Observations made during the testing 3/15/13 SPE179 Appendix B 6 of 7

29 - An estimation of the pounds of nitrogen loaded during the test and the pounds removed - A copy of the current edition of the Owner's Manual - Process description and detailed dimensioned drawings of the system evaluated. A supplemental report shall be prepared for any system(s) approved under the performance classification section (1.4) of this Standard, including process description(s) and dimensioned drawings. 3/15/13 SPE179 Appendix B 7 of 7

62 INTRODUCTION The Clearstream System is one of the finest aerobic wastewater systems available today. Our system converts the sewage from your residence or business into a clear, odorless liquid. This high degree of treatment is accomplished at a remarkable low operating cost per month. The system has been simplified over the years to make it as inexpensive to operate and as low in long term maintenance as possible. Homeowners who have lived with the nuisance of a septic odor lingering in their neighborhood will truly appreciate the pleasure of owning a Clearstream System. Clearstream Model 500D complies with ANSI/NSF Standard 245 for on-site residential and commercial wastewater treatment. PROCESS DESCRIPTION The Clearstream Wastewater Treatment System operates in the extended aeration mode of the activated sludge process. Wastewater enters the trash tank compartment through a 4 Sch. 40 PVC inlet pipe. This anaerobic chamber allows larger solids to settle before the wastewater enters the aeration chamber. Wastewater is then mixed throughout the aeration chamber by releasing compressed air near the bottom of the chamber through fine bubble diffusion. The rising air bubbles transfer oxygen to the wastewater which allows aerobic organisms to thrive and ultimately decompose the incoming waste matter. The turbulence caused by the rising air bubbles also creates a mixing pattern which keeps the sludge in suspension. As incoming wastewater enters the aeration chamber, existing mixed liquor from the aeration chamber is displaced into the bottom of the cone- shaped clarifier. The clarifier chamber allows the water to still so that suspended solids in the mixed liquor can settle back into the aeration chamber for further biological breakdown. The remaining clear water in the upper zone of the clarifier chamber is then discharged by gravity through the surge control weir and out the 4 Sch. 40 outlet pipe to the pump chamber. The final effluent is then discharged by submersible pump to the appropriate disposal system with a portion being returned to the pretreatment tank. When disinfection is required before final discharge appropriate disinfection options are available. When properly loaded and maintained, the aforementioned process allows the Clearstream Wastewater Treatment System to provide years of satisfactory service for the consumer. Clearstream Model D systems met the performance requirements of NSF Standard 245 with a 30 day average of 4 mg/l CBOD, 7 mg/l TSS. Total test averages were 4mg/l CBOD, 7mg/l TSS and 52.9 total nitrogen reduction. *Denotes concrete model 3/15/13 SPE179 2 of 12

63 OPERATING MANUAL In the event you experience a problem with your Clearstream Aerobic Wastewater Treatment System or if service is required, you may reference the Clearstream Control Panel Cover for the name, address and phone number of a local service person that can provide service for your Clearstream Unit. After the expiration of your initial two year service policy provided by the system installer, you may obtain a continuing service policy on a yearly basis which will include terms comparable to the initial service policy from a local service person that is trained and certified by Clearstream. In order for the Clearstream System to function at optimum performance levels, the system will require periodic service. The normally expected service that is associated with the system includes: 1. Repair or replace aerator 2 to 10 years 2. Clean filters on aerator 6 mos. to 2 years 3. Break up scum in clarifier 6 mos. to 2 years 4. Pump sludge from aeration tank 2 to 5 years* 5. Pump sludge from pretreatment tank 2 to 5 years* 6. Check aeration diffusers annually 7. Check surge control weir 6 mos. 8. Check denite effluent return flow 6 mos. * Any sludge removed from pretreatment tank or Clearstream Unit must be disposed of according to all state, local, and federal regulatory requirements. To remove solids from pretreatment tank drop pump hose through access opening on top of tank all the way through to the bottom of the tank. Pump out the whole tank volume, then fill the tank back up immediately. To remove solids from aeration chamber, drop hose through access opening in tank all the way to the bottom of the tank. Pump only 1/2 of the total tank volume and fill tank back up with water immediately. To determine if all system components are functioning properly, look and/or listen to see if the visual/audio alarm system is illuminated or making a buzzing sound. If the alarm is activated, then either the aerator has thrown its breaker or the high level float inside the clarifier is indicating a high water level condition. Verification of either condition can be made by visually monitoring the aerator circuit breaker to see if it has been thrown and opening the access opening to the treatment unit to see if the water level inside the clarifier is at alarm level. After inspection of the clarifier, be sure to securely fasten the access cover back in place and tighten the tamper resistant bolt or bolts firmly. To determine if the system has the desirable mixed liquor and effluent characteristics, first remove the access cover. Monitor for odors coming from the tank. If the odor is a sweet or a musty smell, the system is operating in a desirable aerobic condition. If the odor is foul or smells like a rotten egg, then the system is operating in an undesirable anaerobic condition. Visually monitor the mixed liquor for color. If the color is a brownish color, then it is operating in a desirable aerobic condition. If it is grey or black in color, it is operating in an undesirable anaerobic condition. The system effluent should be clear with very few noticeable light brown solids suspended in the effluent. The effluent should not be dark or turbid in color or clear with great numbers of light brown suspended solids noticeable. After inspection of the system s interior, be sure to securely fasten the access cover back in place and tighten the tamper resistant bolt or bolts firmly. In the event the alarm panel light and buzzer is activated, call your local servicing dealer whose name, address, and phone number should be affixed to the face of the panel. 3/15/13 SPE179 3 of 12

64 effluent discharge. The sample port should be installed so that effluent cannot remain below the discharge water line and build up solids. A sample bottle should be capable of being lowered into the port on a string and laid on its side in the direct flow line of the discharge and removed when full of effluent. The expected effluent from the system should be less than 25 mg/l CBOD and less than 30 mg/l TSS with a PH range of 6-9 and total nitrogen removal of a minimum of 50%. For the first two (2) years from the date of installation, your local servicing dealer (from whom you purchased your Clearstream System) will make periodic inspections of your system to make sure it is functioning properly. The dealer will perform necessary maintenance to the system at no charge unless the required maintenance is not warranty related. Pumping of the system is not included. After the first two (2) years, the dealer will offer a continuing service policy for a nominal annual fee. The two (2) year service policy (two service calls per year) and the continuing service policy are minimum requirements of ANSI/NSF Standard 245 certified wastewater treatment systems. If local service requirements are greater than those of these ANSI/NSF Standards or if the local regulations require others to perform the service on these units, Clearstream s limited warranty will still be honored. For the Clearstream Aerobic Wastewater Treatment Unit to function properly it must be used for the treatment of domestic wastewater from residences or other waste flows with similar loading characteristics. Typical domestic wastewater consists of the flow from toilets, lavatories, sinks, bathtubs/showers, and washing machines. To prevent malfunctions of your Clearstream Unit, the following guidelines should be followed: 1. Any sewage system, whether aerobic or septic, should not have inorganic materials (plastics, cigarette butts, throwaway diapers, feminine napkins, condoms, etc.), that the bacteria cannot consume, discharged into the system. 2. Large amounts of harsh chemicals, oil, grease, high sudsing detergents, discharge from water softeners, disinfectants or any other chemical or substance that kills bacteria should not be discharged into the system. 3. Excessive use of water, over the design flow of the system, or organic overloading in excess of design parameters will cause the system not to perform to its fullest capabilities. 4. The proper operation of this or any other sewage treatment system depends upon the proper organic loading and the life of the micro-organisms inside the system. Clearstream is not responsible for the in-field operation of a system, other than the mechanical and structural workings of the system itself. Field abuse and overloading of the system can only be cured by the user of the system. 5. When wastewater discharge, into a Clearstream Unit, is seasonal or intermittent to a point that the owner wishes to turn off the electricity (for more than three (3) months) to the aerator, the aerator inlet and outlet should be sealed to keep out moisture until the unit is ready to be restarted. 3/15/13 SPE179 4 of 12

65 CLEARSTREAM INSTALLATION INSTRUCTIONS Before installation of the Clearstream Treatment Tank, first install a pretreatment tank (septic tank) with a volume of not less than 50% of the gallon per day rating of the Clearstream Unit. Pretreatment tanks shall comply with minimum sizing specifications outlined in the Clearstream specifications section. CLEARSTREAM TANK INSTALLATION 1. Prepare an excavation having minimum dimensions of at least one (1) foot larger than the dimensions of the tank. Make sure the depth of the excavation is deep enough to allow gravity flow to the inlet of the system and that the excavation bottom is level. Never install the Clearstream tank deeper than a depth that will require more than a maximum of 18 inches of riser depth. The access cover shall always be above final grade after tank installation. In applications where more than the maximum 18 inches of riser is required, install a lift pump upstream of the Clearstream tank in order to pump the pretreatment tank effluent to the Clearstream tank at normal grade. In these special applications where a lift pump is required, contact Clearstream for more details as to pump size, maximum dosages and maximum flow rates. 2. Set the Clearstream tank in a prepared excavation that has a solid, level bottom that will eliminate tank settling. The excavation bottom should have no rocks or sharp objects present. 3. When lowering the concrete tank into the prepared excavation use a spreader bar. Only spreader bars and other lifting devices, that have been designed and tested for lifting Clearstream concrete tanks, should be used. Never lift concrete Clearstream tanks unless they are empty of all liquids. 4. Make sure the inlet 4 Sch. 40 PVC pipe is aligned properly to incoming sewage line. 5. For the Clearstream Unit to function properly, the tank must be level. To properly level the tank, lay a three (3) foot level across the tank in several directions. Shift the tank in the hole, as necessary, to make the tank level in all directions. The tank may be slightly out of level, but it should not be out of level enough to cause tank malfunctions. 6. Fill the tank with water, checking periodically to make sure the tank remains level. 7. Connect the 4 Sch. 40 PVC Clearstream inlet pipe to the incoming sewage line. Make sure the incoming sewage pipe is level with or higher than the inlet pipe to the Clearstream Unit. The Clearstream Unit should only be connected to a plumbing system from a wastewater source which has been properly trapped and vented in compliance with State and Local plumbing codes. 8. Back fill the excavation in layers with back fill material that will settle properly around the tank. Tamp the back fill material as each layer is placed around the tank. If necessary, use water to help settle the soil around the tank. Special care should be taken to either tamp soil under where inlet and outlet pipes are bridging the excavation or use some other method of supporting pipes across the excavation. Do not back fill with heavy clay or large rocks. 9. Before completing the back fill, be sure the electrical conduit from the tank to the Control Panel, air line from aerator to treatment unit, and the return line from flow restrictor, located in pump tank, to pretreatment tank have been laid underground 10. For below normal grade installations a Clearstream 20 inch diameter riser may be used. In no case shall more than 18 of additional riser depth be used on a Clearstream Unit to bring the access covers above the final grade. All risers must be sealed with silicone to prevent ground water intrusion before back fill is completed 3/15/13 SPE179 5 of 12

66 11. Before leaving excavation site, be sure to securely fasten the Clearstream access covers in place with the tamper resistant bolt(s). Tighten bolts firmly to keep unauthorized personnel from gaining access to the inside of tank. CLEARSTREAM AERATOR AND CONTROL PANEL INSTALLATION 1. Mount one of the Clearstream Control Panel Model series CS-118 in a location that can be easily noticed by the occupants. 2. Wire 115 Volt, 60Hz power from an electrical disconnect to Clearstream Control Panel. Wire from Control Panel to Clearstream Tank electrical junction box through conduit. Use wiring diagram provided for each version of the Clearstream Control Panel Model series. All electrical wiring should be installed by a qualified person in compliance with applicable section for the National Electrical Code or other more stringent local codes. 3. Install Aerator Model CS-103 as close as practical to the tank, but in no case greater than one hundred (100) feet away. Run ¾ Sch. 40 PVC air line from aerator connector to air line connection at Clearstream tank. Be careful to back fill underground air line in manner which will not cause air line to leak. Aerator must be installed in a location that is dry, non-dusty, and highly ventilated. 4. Turn power on at electrical disconnect and check for proper system operation. COMPLIANCE WITH LAWS The Clearstream Unit must never be installed without first obtaining all permits and approval from the local regulatory body. In areas that do not have local control over environmental activities, all applicable State and Federal environmental codes must be adhered to as well. Only properly licensed and trained individuals should install Clearstream equipment. 3/15/13 SPE179 6 of 12
