Advanced Treatment Units

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. This product 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 result is simple installations in a smaller soil absorption area. 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 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

NextGen Septic technology

Treated water exiting NextGen Septic technology meets higher water quality standards than treated water leaving a typical centralized wastewater treatment plant. The system is suitable for sites traditionally requiring costly drainfield construction due to size restrictions and/or hilly, rocky, clay or sandy soil conditions. It is approved for surface discharge in Kentucky, and it uses a combination of anoxic treatment of the raw wastewater followed by aerobic degradation of the contaminants. An ultrafiltration membrane further treats the water before being disinfected using ozone. Treated water has less than 15 mg/L of BOD5 less than 2 mg/L ammonia, less than 1 mg/L phosphorus and no TSS. Ozone decomposes to oxygen, which increases the dissolved oxygen level in the discharged water. This treated water can be used for irrigation or to resurrect a clogged leachfield. 513-673-3583; www.nextgenseptic.com

Presby Environmental Advanced Enviro-Septic

Advanced Enviro-Septic (AES) from Presby Environmental is a combined treatment and dispersal system for residential, commercial and community use designed to remove 99% of wastewater contaminants. It requires no replacement media or additives and no electricity or mechanical devices. The NSF 40 Class 1 certified system treats effluent efficiently, providing long system life and protecting the environment, according to the maker. It quickly and naturally establishes multiple bacterial treatment environments throughout the system to break down and digest wastewater contaminants that leave the septic tank. Following the filtering of suspended solids, it releases highly purified wastewater to the soil, recharging the groundwater and preventing soil and groundwater contamination. It is BNQ (Bureau de Normalisation du Québec) certified for secondary and advanced secondary treatment. 800-473-5298; www.infiltratorwater.com/products/presby-environmental

Orenco Systems AdvanTex AX-Max

AdvanTex AX-Max wastewater treatment systems from Orenco Systems are containerized, fully plumbed units sized for larger commercial and municipal applications. Units come in a variety of configurations, measuring up to 42 feet long by 8.5 feet wide. They can be installed as a single unit or in multi-unit arrays, either above ground or buried to grade. Systems use an attached-growth treatment method to produce clear, odorless effluent with significant nutrient reduction, suitable for subsurface irrigation or surface discharge after disinfection. One unit can process up to 5,000 gpd of raw sewage or 15,000 gpd of primary-treated effluent. Units reduce nitrogen up to 90%, depending on configuration, and can be operated with a part-time operator. They are easy to ship and set and can be installed in a variety of soils and climates. 800-348-9843; www.orenco.com

High-Strength Wastewater Treatment

Anua PuraACE

The PuraACE from Anua is a drop-in-tank reactor pod for treating high-strength waste from restaurants, convenience stores or other facilities. The pods can be added to residential or commercial treatment systems that are overloaded. Treatment occurs by a submerged aerated filter process to reduce BOD, COD and ammonia. Built-in passive alkalinity control regulates pH without chemical addition. The pod housing isolates aeration to keep the heavy solids from mixing. The open channel media prevents clogging while the airlift recirculation enhances retention time. Multiple pods can be utilized for larger flows and loads. 336-547-9338; www.anuainternational.com
