Manufacturer Technology Product Description
Orenco Systems Inc AdvanTex® AX Series Orenco's AdvanTex AX20 Treatment Systems provide environmentally sustainable treatment of residential wastewater flows. They are the ideal solution for difficult soils, small sites, system upgrades and repairs, new installations, pretreatment, nitrogen reduction, and disinfection.
Norweco Systems Singulair® Model TNT® Total Nitrogen Treatment System Certified performance data from NSF International verifies that the average effluent produced by the Singulair Model TNT system contains 7 mg/L Nitrate, 12 mg/L Total Nitrogen, 4 mg/L CBOD5 and 9 mg/L Total Suspended Solids. The Singulair Model TNT reduces Total Nitrogen by more than 68%. Featuring flow equalization, effluent filtration and the lowest electrical usage in the industry, this advanced treatment unit biologically oxidizes nitrogen compounds to accomplish nitrification and denitrification. Designed for easy installation, operation and maintenance, the Model TNT system minimizes effluent nitrogen concentrations reliably and economically. The Singulair Model TNT System delivers state-of-the-art performance without requiring effluent recirculation or the addition of dangerous chemicals. All treatment is efficiently accomplished within the precast concrete Singulair tank.
Norweco Systems Hydro-Kinetic Wastewater Treatment System The Hydro-Kinetic system uses the extended aeration and attached growth processes to treat wastewater, and features innovative nitrification-denitrification technology. Achieved unmatched effluent results of 2.0 mg/L CBOD (Carbonaceous Biochemical Oxygen Demand), 2.0 mg/L TSS (Total Suspended Solids) and 7.9 mg/L TN (Total Nitrogen).
Hydro-Action Hydro-Action AN Series The Hydro-Action system outperforms traditional septic tanks in prolonging drain field life, meeting environmental requirements, and handling issues like poor soil or high groundwater. Before wastewater enters the ATU, it runs through the pretreatment or septic tank. Pretreating reduces the amount of solids and other materials that can get into the system. The system’s flexibility allows the ATU to be added to an existing septic tank or used with the Hydro-Action system alone.
F R Mahony & Associates Inc Amphidrome® Utilizing Biologically Active Filter (BAF) high biomass technology, the Amphidrome® system provides simultaneous removal of BOD, ammonia, suspended solids and nitrate-nitrogen in an extremely small footprint.
BioMicrobics Inc SeptiTech The SeptiTech STARR™ biological trickling filter systems are designed to treat wastewater with minimal operator oversight while delivering consistently high quality treatment even during peak flows, low flows or intermittent flows.
Fuji Systems Fuji Clean CEN Series The CEN5 is Fuji Clean USA's most compact system, which can comfortably treat up to 4 bedrooms of straight wastewater. No preceding septic tank is necessary and not required (unless dictated by state or local regulations). A very small footprint (7'1" x 3'8") and weight of just under 400 pounds makes this system highly maneuverable and adaptable to the very tightest and most difficult-to-access sites. Designed to accommodate variable flows and shock loadings, this low power draw (54w) low maintenance compact system is a natural choice for a single family home.
Center for Clean Water Technology Nitrogen Reducing Biofilters (NRBs) New York State recently established the NYS Center for Clean Water Technology (CCWT) at Stony Brook University, whose primary objective is to develop and commercialize wastewater treatment systems for individual onsite (household) use that are affordable and highly efficient at removing nitrogen and other contaminants. The CCWT has identified Nitrogen Reducing Biofilters (NRBs) as a system capable of meeting this goal. NRBs are relatively passive technology that uses layers of sand and woodchips to treat wastewater, reducing nitrogen to 6 - 12 mg/L (on average as of 2024) and removing the majority of more than two dozen drugs, pharmaceuticals, and other organic contaminants. Today, CCWT has installed more than 30 NRBs across Suffolk County with their lined NRB system provisionally approved and their box NRB system approved for pilot use. Visit for additional information.
Hoot Systems Hoot-ANR The Hoot ANR wastewater treatment system utilizes extended aeration, activated sludge and fixed film filtration processes. In the activated sludge process, microorganisms remove soluble contaminants from the wastewater. Extended aeration is a modification of the activated sludge process in which the microorganisms are allowed to remain in the treatment process for long periods of time. The long aeration period allows for the organisms in the system to consume themselves, reducing the total amount of solids produced by the treatment process. Finally, the Hoot ANR incorporates an attached growth media chamber for additional nitrogen reduction.
Aquapoint Aquapoint BioClere Bioclere™ is a modified trickling filter over a clarifier (settling tank) that is designed to treat wastewater with varying organic and nutrient concentrations. Its natural fixed-film biological treatment process is resilient, energy efficient, compact and simple to operate. Within the Bioclere filter, wastewater is evenly distributed over the surface of plastic media where microorganisms known as biomass attach themselves to the media and consume BOD/COD and ammonia-N. Residual solids from the treatment process settle in the clarifier below the filter and are evacuated by a recirculation pump while clean effluent leaves the system by gravity. Modular Bioclere™ units can be installed in parallel to treat large flows or in series to achieve higher performance standards.
Delta Environmental ECOPOD – N Series ECOPOD-N directly contributes to a cleaner, safer environment using the bacteria nature provides. As a result of air being pumped into the system, the bacteria thrive and grow in much greater numbers than would occur naturally. This “overpopulation” of bacteria speeds the process of breaking down the sewage, making it safe for release into the environment. ECOPOD-N significantly reduces BOD, TSS, fecal coliforms, and nutrients in the wastewater. Nitrification and denitrification occur in a single tank. ECOPOD-N series uses a fixed film process which is characteristically stable, reliable and sturdy. Fixed film is a preferred treatment process for on-site wastewater treatment systems.
Nitrex Advantex / SeptiTech / Waterloo Biofilter + Nitrex The NITREX™ reactive media is contained in a prefabricated tank or, for larger installations, in an engineered excavation. Nitrate contaminated wastewater is gravitationally fed through the treatment module. Pre-treatment can be achieved with any of the existing oxidative technologies commonly used in wastewater treatment.

PuraSys SBR transforms an ordinary septic tank into a compact, advanced treatment unit. The PuraSys SBR batches treatment through cycles, including aerobic and anaerobic steps, to clean the water and reduce total nitrogen. Since the process is batched, the smart control can recognize water flow and then adjust aeration accordingly. This not only saves energy, but also improves treatment efficiency and avoids bulking.

AeroCell utilizes synthetic media housed in an engineered pod. The open cell foam cubes have high surface area and porosity, which balance water movement and oxygen availability. The media will not degrade over time and has a three-decade track record of performance. Pretreated effluent is sprayed over the foam cubes using specially designed helical spray nozzles that provide uniform distribution over the entire surface area within the pod. Treated effluent is recirculated through the media multiple times, which optimizes treatment.

BioCoir utilizes coconut fiber (coir) media housed in an engineered pod. Coir are the fibers that constitute the thick mesocarp, or husk, of the coconut fruit. Coconut fiber is low-cost and a renewable resource. The short-to-medium length fibers are a lingo cellulosic material and by-product of coconut harvesting in many developing nations. The high lignin content of these fibers results in a durable material. Pretreated effluent is sprayed over the media using specially designed helical spray nozzles that provide uniform distribution over the entire surface area within the pod. Treated effluent is recirculated through the media multiple times, which optimizes treatment.
