BioMicrobics RetroFAST
Both the RetroFAST and RetroFITT-ee (energy efficient) units from BioMicrobics are designed to be a simple upgrade to enhance a conventional septic system or renovate a biologically failed septic system. A unit can be installed inside an existing tank to create an optimized treatment environment using submerged, fixed-film media for microbial growth with an energy efficient aeration system. It constantly sends effluent rich in dissolved oxygen to the drainfield. Where sites and regulations allow, it can be used in new installations. It is designed to deliver high levels of treatment to help ensure clogging layers don’t form. 800-753-3278; www.biomicrobics.com
Eljen Geotextile Sand Filter
The GSF, or Geotextile Sand Filter, advanced wastewater treatment and dispersal system from Eljen is designed to provide treatment and dispersal in the same footprint, easy installations and minimal maintenance. It is used for both commercial and residential applications. Utilizing a two-stage pretreatment process, the geotextile modules apply filtered septic tank effluent to the soil and increase the long-term acceptance rate. Open-air channels within the module support aerobic bacterial growth on the module’s geotextile fabric, surpassing the surface area required for traditional absorption systems. The system is tested and certified by NSF to NSF/ANSI Standard 40. 800-444-1359; www.eljen.com
MicroSepTec EnviroServer ES
The MicroSepTec EnviroServer ES series utilizes five chambers to achieve primary settling, treatment and clarification in one tank. The units use a moving-bed biological reactor made specifically for the residential market. The first compartment of the system is the primary clarifier for settling sludge and solids. The second section houses the first of two aeration chambers and contains biomedia providing surface area to promote a healthy population of microorganisms. The third compartment is used for further aeration to amplify the growth of nitrifying bacteria and the process of nitrification. The fourth chamber is the final clarifier where suspended solids settle out. Wastewater is then recirculated back to the primary clarifier in the first compartment, which contains enough carbon to promote denitrification removing high levels of nitrate. Clarified water then moves through an effluent filter before entering the fifth compartment, an effluent chamber for storage. 877-473-7842; www.microseptec.com
Orenco Systems AdvanTex AX-RT Series

The design includes recirculation, treatment and discharge in a single unit to simplify installation and eliminate the need for additional tanks, basins, risers and lids. The system can be maintained with an annual service call. Filters and textile media are accessible and cleanable, and control panels are touch-safe. No blower is needed for the passively vented system. An optional UV disinfection unit is available. 800-348-9843; www.orenco.com
Zoeller Pump Company Clarus Fusion
Clarus Fusion systems from Zoeller Pump Company are drop-in wastewater treatment units designed for decentralized applications where effluent quality must meet or exceed secondary treatment standards. They are designed for residential, commercial and small community applications and are available in 450 to 4,000 gpd treatment capacities. All models up to 800 gpd are NSF/ANSI Standard 40 certified to produce effluent quality of 9 mg/L CBOD5 and 9 mg/L TSS. The design enables installation without a pretreatment tank, making it suitable for sites with limited space. Effluent disposal options include conventional trenches, dosed systems, drip irrigation or disinfection with direct discharge. 800-928-7867; www.zoellerpumps.com
Nitrogen Reduction Systems
Eliminite Commercial C-Series
The Commercial C-Series system from Eliminite is designed to provide reliable treatment with emphasis on total nitrogen reduction for high-strength waste applications such as work camps, RV parks, restaurants, ski and golf resorts, breweries, mines and agricultural operations. It is designed to work with locally sourced tanks and components when possible. MetaRocks treatment media is designed to withstand a variety of high-strength waste-loading scenarios, particularly where clogging and odor control are major considerations. The system is scalable and may be adapted to suit specific phasing requirements, site constraints and unique demands. 888-406-2289; www.eliminite.com
Jet Inc. J-1500CF Series
The J-1500CF Series nutrient-reducing BAT media plant from Jet Inc. offers variable capacity in an NSF-245-tested treatment system. It provides complete effluent treatment from 500 to 1,500 gpd. The 500 and 800 gpd PLT Series tanks are the lightweight, rotational molded alternative to the concrete J-1500CF Series. The seamless polyethylene tanks are easy to transport and install in difficult site conditions. The system uses a 700++ aerator, effluent filter and the Jet 197 control panel, which cycles the aerator to reduce nitrogen by over 60%. 800-321-6960; www.jetincorp.com
Recirculating Filters
Anua BioCoir
The BioCoir recirculating media biofilter from Anua is designed to be simple to install and easy to operate. It provides stable treatment across a broad range of applications with no constantly running noisy blowers or motors, according to the maker. It uses coconut coir media housed in a preassembled pod. Coir refers to the fibers that make up the thick husk of a coconut. The coconut fiber is low cost, an upcycled resource and high in lignin content, which results in a durable material. Pretreated effluent is time-dosed over the media using helical spray nozzles to provide uniform distribution. Treatment is optimized by recirculating effluent through the media multiple times. It is certified to NSF/ANSI Standard 40, Class I and third-party tested to reduce nitrogen by more than 50%. Residential and commercial configurations are available. 336-547-9338; www.anuainternational.com
SeptiTech STAAR filter systems
SeptiTech STAAR (Smart Trickling Anaerobic/Aerobic Recirculating) filter systems are designed for residential and commercial properties with minimal operator oversight, while delivering consistent treatment during peak, low or intermittent flows. Using an unsaturated, engineered textile media to treat wastewater that meets strict permit limits, the commercial filter system provides a simple, automatic equalization and clarification process for 500 to more than 150,000 gpd flows, according to the maker. The biological trickling filter technology also maintains low levels of Nitrate-N, with all below-grade components that fit in watertight concrete, plastic or fiberglass tanks. Smart technology allows the system to go into sleep mode to achieve lower operating costs and power requirements. Systems are Environmental Technology Verification-U.S. Environmental Protection Agency verified and NSF/ANSI Standard 40/245 certified. 800-753-3278; www.septitech.com
