4 NRFS Information General Information The Nutrient Removing Filtration System is a denitrifying media treatment vault that is commonly used at the end of a detention pond or for off line pretreatment applications. The NRFS is an orifice driven treatment vault for the removal of phosphorus, nitrogen and total suspended solids. Bold & Gold Biosorption Activated Media (BAM) is the exclusive media of choice in the NRFS vault system. The NRFS removes both solids and dissolved contaminates for water quality improvement projects. Equipped with the innovative HydroSlide system, debris removal is easy and efficient without the need to enter the structure. Benefits Low maintenance (media does not require removal for servicing). Easily retrofits existing watersheds. No organics to degrade and lose treatment capability. Servicing is accomplished quickly using a vacuum truck. Removes phosphorus, nitrogen and TSS. Uses genuine Bold & Gold Biosorption Activated Media. Nutrient Removing Filtration System depicting stormwater flow and filtration through Bold & Gold media.

5 Inspection Information Inspection Summary Suntree Technologies, Inc. recommends the following inspection guidelines: The Bold & Gold media is positioned vertically between two layers of river rock. The layer of rock below the Bold & Gold should be 6-10 thick and the layer above should be 6 thick. The Bold & Gold layer itself should be 30 thick and is possible to never need servicing. To determine if the media bed requires servicing, visually inspect the top layer of the media bed for any type of debris. It is safe to assume that the top layer of the media bed is the only place that would accumulate any debris. The decision to service the NRFS is based on the amount of debris accumulated on top of the media bed and if it is negatively impacting treatment flow rates. All inspections must be documented using the included inspection checklist. Visually inspect the vault from the surface for broken or missing hinges / handles. Open all access points (Manholes / Hatches) and secure each of them properly. Visually inspect the sediment chamber to determine the approximate accumulated sedimentation capacity. Inspect the conditions of all joints and the inflow / outflow pipe grout areas for cracks and wear. Nutrient Removing Filtration System Operation and Maintenance Manual 05

7 NRFS Operation Information Operation Summary The Nutrient Removing Filtration System utilizes Bold & Gold biosorption activated media without the need for cartridge filters affording a more cost effective and efficient solution. Furthermore, the use of Bold & Gold media can accommodate high flow rates without organics which degrade and lose effectiveness over time. Stormwater enters the NRFS and flows upwards through the Bold & Gold Media. Vault specifications allow for 24 hour detention for maximum efficiency and media contact. During high or extreme flows the NRFS resists clogging. (If the SkimBoss floating skimmer is equipped, it will rise to allow water to bypass media filtration) Up to 80% reduction of total nitrogen and up to 90% reduction in total dissolved phosphorus based on site conditions and treatment area.

8 Service Requirements and Parts Minimum Equipment Requirements The use of a vacuum truck is required for servicing of the Nutrient Removing Filtration System. Service crews are recommended to check all local, state and federal guidelines for servicing and disposal of any collected debris and sediments. Structural Components The structural components of the NRFS are designed to have a life span of several decades. Structural inspections are not required unless stipulated in guidelines set by the local municipality, state or federal agencies. Caution! Any Service Work done in Traffic Areas must meet all DOT Roadway Work guidelines and necessary Safety Procedures. Warning! All OSHA confined space requirements must be met while cleaning any of the Nutrient Removing Filtration System structures. Replacement Parts All interior components are designed and sized to be assembled and removed from the NRFS for servicing or for parts replacement. This can easily be accomplished via the access ports atop the structure.

9 NRFS Maintenance Maintenance Summary The Nutrient Removing Filtration System is easily serviced with the use of a vacuum truck combined with the equipped HydroSlide service system. The HydroSlide system allows the media to be back flushed and reused during servicing without removal. Furthermore, the vacuum system eliminates the need for confined space entry. Vacuum Servicing Remove the manhole covers or open hatches. Lower the vacuum truck hose into the vault closest to the inflow pipe. Attach the vacuum truck water supply hose to the HydroSlide service system quick connector. Start the HydroSlide service system using the vacuum truck hose while operating the vacuum line. Debris will be quickly and easily flushed toward the vacuum line and removed. Remove vacuum line and disconnect truck water supply hose. Replace manhole covers or close top hatches. The use of a vacuum truck allows for easy debris removal without entering the structure. HydroSlide quick connector with vacuum truck water supply hose attached debris removal. Each Nutrient Removing Filtration System comes equipped with the HydroSlide service system (seen below the media in above image) for easy maintenance via a vacuum truck.

10 Bold & Gold Media General Information Bold and Gold is a Biosorption Activated Media (BAM) for pollution control to reduce nitrogen and phosphorus in stormwater. Common uses are for filtration systems at the end of detention pond outflows or for pretreatment in rain water harvesting. Further benefits of using Bold and Gold Media include: Available in various sizes for particular applications Up to 2.5 gpm flow rate / square foot of surface area Economical and lower cost than other media Made from recycled materials Effectively removes up to 95% Phosphorus, 75% Nitrogen and 95% Total Suspended Solids Sustainable: Eco Friendly Bold & Gold media is a patented biosorption activated blend designed for enhanced stormwater treatment. It contains no organics to shrink and lose treatment capacity. Bold & Gold Media was Developed by the University of Central Florida Stormwater Management Academy. Only genuine Bold & Gold (BAM) media is accompanied by a certificate of authenticity with each purchase. High Surface Area No biological toxic effects Physical filtration for the removal of solids Sorbent surface bonding for the capture of dissolved pollutants Biological activity including nutrient based consumption and denitrification Nutrient Removing Filtration System Operation and Maintenance Manual 10

11 Bold & Gold Replacement Media Replacement Procedure (If Necessary) It is estimated that the physical filtration and biological activity of Bold and Gold may last indefinitely. However, the sorbent surface bonding may diminish after a period of 15 years and therefore may require replacement. It is important to determine a baseline removal efficiency of the unit when the system is first installed. If it is determined that the Bold & Gold is to be replaced, proceed with the following steps for replacement: 1 Determine the appropriate amount of Bold & Gold needed for replacement by first contacting Suntree Technologies Inc or your local distributer. Stone can be purchased from local distributors. 2 Open all access points. 3 Using a vacuum truck, suction out all media and stone from the media bed. When the vacuum line reaches the lower layer of stone be careful to not move or dismount the underdrain. The underdrain pipes will not be glued into the pipe fittings and can be disassembled to more easily remove the stone and debris underneath the pipes. 4 Reassemble the underdrain pipe system. 5 Install the new stone around the underdrain pipes to a depth of 10 thick. Be careful when placing the stone over the underdrain pipes to avoid any damage. 6 Install the new Bold & Gold to form a layer 30 thick. 7 Install the top layer of stone to form a 6 thick layer. 8 Close all access points.

12 SkimBoss Skimmer Information General Information The included SkimBoss Floating Skimmer prevents floating solids and liquids from passing through the vault. Through the use of Hydro-Variant Technology, the SkimBoss Floating Skimmer can automatically adjust to accommodate variations in water level and flow with a negligible head loss. The SkimBoss skimmer adjusts the hydraulic grade line via Hydro-Variant Technology during high flows. Primary buoyancy is on the front inflow side of the SkimBoss to match rising water levels regardless of outflow side levels. Once the hydraulic grade of the water reaches a point that is 20 above the bottom of the skimmer, the entire skimmer begins to float. During especially high flows in the NRFS, the SkimBoss will rise and allow the water to bypass media filtration as to prevent flooding.
