4 Nutrimax Information General Information The only engineered wetland designed to maximize Bold & Gold biosorption activated media for superior nutrient reduction. The Nutrimax does not require a prefilter, eliminating the clogging and failures associated with other linear constructed wetlands. The Nutrimax combines variable hydraulics, with drainage conveyance and multilevel treatment techniques, for advanced removal of nutrients, debris and metals. Treatment is both flow and detention based, making the Nutrimax ideal for use in Ultra Urban areas and parking lots with limited space. The inclusion of Hydro-Variant Technology allows for an extensive treatment level during low flow events without compromising watershed hydrology during peak flows. The Nutrimax vegetated bioretention system is able to remove nitrogen, phosphorus, metals, bacteria and total suspended solids. By utilizing a combination of physical, biological and chemical processes, the Nutrimax is able to remove solids, nutrients and dissolved contaminates for water quality improvement efforts. Benefits Uses genuine Bold & Gold Biosorption Activated Media No prefilters required, media resists clogging No organics to degrade and lose treatment capability Easy vacuum truck servicing Removes phosphorus, nitrogen and TSS Media removal not required for servicing procedures Retrofits existing watersheds Design blends with landscape Multi stage treatment system Nutrimax Operation and Maintenance Manual 04

5 Inspection Information Inspection Summary Suntree Technologies, Inc. recommends the following inspection guidelines: The Bold & Gold media is positioned between the underdrain shelf and a top layer of river rock. The rock layer should be 4-6 thick and will also comprise of surface plantings, while the Bold & Gold layer should have at least a 32 depth. To determine if the planting or media beds require service, inspect the planting and top of the media bed for debris, sediment and for plant health. The outflow filter chamber houses a High Capacity Curb Inlet Basket to capture any trash, debris and sediment flowing toward the outflow. The HCCIB should be checked regularly for captured pollutants and serviced either quarterly or when full. All inspections must be documented using the included inspection checklist. Visually inspect the vault from the surface for planting / media bed damage and plant life health. Inspect the lower chamber to determine sediment capacity. Open and inspect the outflow chamber HCCIB to assess pollutant capacity and determine if service is necessary. Inspect joints and outflow pipe grout areas for wear.

7 Nutrimax Operation Information Operation Summary The Nutrimax utilizes Bold & Gold biosorption activated media, eliminating the clogging and failures associated with other linear constructed wetlands. Nutrimax uses advanced biofiltration for the removal of TSS, phosphorus, nitrogen, metals, litter and foliage. The system combines drainage conveyance, multilevel treatment techniques and variable hydraulic capabilities, along with easy and inexpensive service methods. The shielded underdrain prevents clogging allowing for unrestricted conveyance. Stormwater sheet flow enters from parking lots, roads, sidewalks and other non porous surfaces. Maximum contact with Bold & Gold allows for passive filtration and biofiltration. Bold & Gold and surface plantings absorb nutrients and dissolved pollutants, promoting biological consumption and denitrification processes. Hydro Variant Technology enabled shielded underdrain accommodates flow variations and prevents clogging. Integrated bypass with high flow treatment system retains trash and debris eliminating the need for a separate bypass.

8 Service Requirements and Parts Minimum Equipment Requirements The use of a vacuum truck is required for servicing of the Nutrimax. Service crews are recommended to check all local, state and federal guidelines for servicing and disposal of any collected trash, debris and sediments. Caution! Any Service Work done in Traffic Areas must meet all DOT Roadway Work guidelines and necessary Safety Procedures. Structural Components The structural components of the Nutrimax 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. Replacement Parts All interior components are designed and sized to be assembled and removed from the Nutrimax for servicing or for parts replacement. This can easily be accomplished via the open planting bed and / or the outflow filter access cover atop the vault structure.

9 Nutrimax Maintenance Maintenance Summary The Nutrimax is serviced with the use of a vacuum truck combined with the HydroSlide service system. The HydroSlide service system enables the lower settling chamber to be easily emptied and the Bold & Gold to be back flushed during servicing. There is no need to remove or replace the Bold & Gold for several years. Because the media is serviceable, there is no need for prefilter cartridges, vastly reducing service frequency. Furthermore, the ease of access to the outflow HCCIB filter, via manhole, allows for efficient and easy debris removal via vacuum truck or by hand. Vacuum Servicing: Sediment Chamber Lower the vacuum truck hose into the service portal. Attach the vacuum truck water supply hose to the HydroSlide quick connector. Start the HydroSlide using the water supply hose while operating the vacuum line. Debris are quickly flushed toward the vacuum line and removed. View of service portal interior including vacuum truck hose space and HydroSlide quick connector connections for vacuum truck water supply hose attachment. Vacuum or Manual Servicing: Outflow Filter Remove the manhole cover. Remove screen system basket by hand or lower the vacuum truck hose into filter screen to remove debris. Cut zip ties, dispose of StormBoom and replace. Brush filtration basket screens clean if necessary. Replace filtration basket and replace manhole cover.

10 Bold & Gold Media General Information Bold & Gold is a Biosorption Activated Media used for pollution control to reduce nitrogen, phosphorus, TSS and turbidity levels in stormwater. High phosphorus and nitrogen levels have the potential to compromise human health as well as ecosystem integrity. Bold & Gold media is ideal for pretreatment prior to rainwater harvesting or following detention prior to discharge into receiving bodies of water. Suntree Technologies Inc is the only company in the USA licensed to include Bold & Gold inside of a treatment vault system. Further benefits of using Bold and Gold Media include: Bold & Gold media is a patented biosorption activated blend designed for enhanced stormwater treatment. It contains no organics to shrink and lose treatment capacity. Available in various sizes for particular applications 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 High Surface Area No biological toxic effects Physical filtration for the removal of solids 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. Sorbent surface bonding for the capture of dissolved pollutants Biological activity including nutrient based consumption and denitrification Nutrimax 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 5-7 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 Using a vacuum truck, suction out all media and stone from the media bed. When the vacuum line reaches the underdrain shelf, be careful to not move or dismount the underdrain. 3 Install the new Bold & Gold layer around the underdrain pipes to a depth of at least 32 thick. Be careful when placing the top stone layer to avoid any damage to the service portal or associated underdrain pipes. 4 Install the top layer of stone to form a 4-6 thick layer. 5 Replant vegetation within the top stone layer. Be careful not to disturb or damage the underdrain if servicing or replacing the Bold & Gold media bed. Nutrimax Operation and Maintenance Manual 11
