Second stage nitrification

NitriFAST systems from Bio-Microbics provide second stage nitrification when wastewater contains higher than normal nitrogen levels or when effluent requirements for ammonia/total nitrogen require higher levels of nitrification. The system improves the nitrification of a complete biological removal system with the same technology as the company’s other FAST systems, which reduce nitrogen levels. Multiple processes occur simultaneously with integrated fixed-film treatment that provides a high surface-to-volume ratio to maintain strong microbial growth during low, average and peak usage. 800/753-3278; www.biomicrobics.com.

Simple ATUs

Bluewater aerobic treatment units are designed to be simple, strong and efficient. The units have no moving parts and deliver effluent with less than 5 mg/L BOD and 8 mg/L TSS. They are certified and listed as Class I Advanced Treatment Units by NSF, and are self-contained, compact, easy to transport and quick to install. There are no control panels to program, and no internal vanes or pumps. The entire system can be hooked up in about three hours. The ATUs break down 100 percent of organic waste, leave no odor, and operate 20 times faster than a septic tank, according to the manufacturer. Minimal maintenance is required. 615/663-0500; www.bluewateratu.com.

Sand filter system

The GSF geotextile sand filter system from Eljen Corp. is comprised of a two-stage Bio-Matt pretreatment process that provides treatment and disposal in the same footprint. Installation is easy, and maintenance in minimal. The unit complies with the requirements of ANSI/NSF Standard 40 protocol.

Septic tank effluent is filtered through the Bio-Matt fabric while the module’s design provides a large surface area for biological treatment. Open-air channels within the module support aerobic bacterial growth on the geotextile fabric interface. Effluent passes through the unit and slowly drips into the specified sand layer that surrounds it. The result is an unsaturated flow zone. 800/444-1359; www.eljen.com.

Cloud-based monitoring

The Generation VI product line from Envirocycle USA includes the 600, 1,200 and 3,600 gpd treatment systems. New treatment technology and clean manufacturing processes make the units easy to install and transport. Products meet all three NSF certification requirements. With minimal external connections and no on-site internal plumbing or wiring required, the systems can be installed quickly with minimal training.

EnviroSentry remote monitoring and control cloud-based system with military-level encryption and communication security provides individual real-time treatment unit control, two-way customer messaging, automatic contact billing, three-level service scheduling, paperless field reporting, Android and iPhone app and widget interfaces, and predictive service notification features. 888/694-4633; http://cole.thesepticexperts.com.

Commercial plants

Commercial wastewater treatment plants from Jet, Inc. are modular to allow for phased buildout and can treat up to 300,000 gpd. The plants use an aerobic digestion process that enables microorganisms to transform wastewater into a clear, odorless liquid. Assistance with design, engineering, construction, and 24/7 technical support is available. 800/321-6960; www.jetincorp.com.

Advanced oxidation

The advanced treatment system from Koi Environmental includes a compact, high-efficiency, low-energy cold plasma ozone generator. Generating ozone and then combining the ozone and mixed oxidants with polychromatic UV light provides a level of treatment for a broad range of contaminants.

The system uses advanced oxidation, which involves a saturated oxidative environment for removal of traditional contaminants like settleable solids, dissolved and suspended solids, pathogens, and odors, as well as nontraditional contaminants such as formaldehyde, disinfectants, solvents, pesticides, and hydrocarbons. The low-maintenance modular system requires minimal operator skills. 800/980-9898; www.koienvironmental.com.

Green treatment unit

The Singulair Green wastewater treatment unit from Norweco treats up to 600 gpd and is ANSI/NSF Standard 40 certified. It uses polyethylene single-tank technology with integral pretreatment, flow equalization and disinfection.

The multidirectional ribbed design is UV stabilized, durable, leakproof and corrosion resistant. The unit weighs less than 1,000 pounds and is easily installed by two people with a backhoe. The system offers a solution to tank delivery challenges, such as limited site access and steep grades. Structural integrity allows the tank to be buried with up to three feet of fill on top. 800/667-9326; www.norweco.com.

Vacuum technology

VBT (vacuum bubble technology) from O2 Aeration Technologies is designed to enhance BOD removal by improving the performance of aerobic bacteria in consuming organic wastes. VBT aerators create bubbles with vacuum rather than pressure. The bubbles are a fraction of the size of bubbles from pressure aerators, so they collapse under the weight of the water and are neutrally buoyant.

The tiny bubble size ensures maximum surface contact with water. Because the bubbles do not race to the surface, they can last for many minutes and provide high oxygen transfer potential to the effluent. 888/801-1586; www.paulswoyerseptics.com.

Self-contained module

The AdvanTex AX20-RTUV treatment system from Orenco Systems is a complete, self-contained module for treating septic tank effluent. A four-in-one design performs recirculation, treatment, discharge, and disinfection in a single unit instead of separate tanks or basins. All interior components on the plug-and-play module are pre-plumbed.

The unit is easy to maintain and access. It can be shallow-buried for use between an existing functional septic tank and a functioning drainfield. It also offers a replacement option for failing systems. The UV unit is protected within the tank, and its electrical ballast is protected inside the control panel. It uses no chemicals, has no moving parts, and needs only annual cleaning, and every-other-year bulb replacement. The unit treats waste to less than 10 mg/L BOD5 and TSS, producing clean, odorless effluent. 800/348-9843; www.orenco.com.

STEP system

The Polylok STEP (septic tank effluent pump) system draws effluent from the middle layer (clear zone) of a septic tank, filters the remaining unwanted solids, then pumps the effluent to either a dispersal field or wastewater treatment system. The system installs quickly in a 24-inch-diameter opening in concrete or fiberglass tanks.

The dual-compartment design allows the filter cartridge to be removed without pulling the pump or the entire vault. The system includes a polyethylene basin, effluent filter, 0.5 hp high-head turbine effluent pump (10, 20 and 30 gpm versions available), internal piping, float switches and a control panel. 800/701-3946; www.polylok.com.

Advanced treatment

The Advanced Enviro-Septic (AES) system from Presby Environmental is an effective, passive and nonmechanical onsite wastewater treatment system for residential, commercial and community use. The system is NSF Class I certified and BNQ certified for secondary and advanced secondary treatment.

It can remove up to 99 percent of wastewater contaminants by establishing multiple bacterial treatment environments throughout the system that break down and digest contaminants that leave the septic tank. The natural process allows the system to discharge highly purified wastewater, preventing soil clogging and groundwater contamination. No electricity or replacement media are required. 800/473-5298; www.presbyenvironmental.com.

3G UV disinfection

The 3G ultraviolet onsite wastewater disinfection unit (UL and cUL Certified) from Salcor features a fouling-resistant Teflon lamp covering, quick installation, minimal annual maintenance, and low energy use. The 3G unit is listed by Underwriters Laboratories for USA and Canada (cUL) under Standard 979 for treating onsite effluent. Applications include residential, commercial and municipal. The unit passed 30-day submerged testing and is rated NEMA 6P (flood proof). It can operate in the ground or in a pump tank, eliminating the need for an aboveground control box or panel.

Other features include an alarm circuit, a rugged heavy-clad conformal-coated circuit board, electrical surge protection, and virtual elimination of electronic noise (EMI). Electronic components are mounted on the underside of the top cover of the electrical enclosure, to avoid condensed liquid collection and provide user-friendly access. 760/731-0745.
