Allied Waterproofing & Septic seldom installs conventional septic systems.
That’s because in the northeastern Illinois counties where the company works, many sites have some combination of difficult soils, high bedrock and high seasonal water tables.
Most of the company’s systems require lift stations, and many include aerobic treatment units. Allied Waterproofing is a distributor for Norweco and often installs Singulair R3 ATUs, according to Christopher Friedsam, chief operating officer.
Singulair R3 systems are designed to reduce water consumption. They reuse treated effluent, recycle water and minimize energy costs. They operate quietly and efficiently, automatically treating septic tank effluent to high levels for unrestricted outdoor and restricted indoor use.
The manufacturer says Singulair R3 units outperform the effluent requirements of NSF/ANSI Standards 40, 245 and 350. Rated Class R through completion of NSF/ANSI Standard 350 test protocols, the systems produce effluent that averages 5.0 mg/L CBOD, 4.6 mg/L TSS, 2.3 NTU turbidity and 2 MPN/100 ml E. coli. In addition, the systems meet NSF/ANSI Standard 245 by reducing total nitrogen by 66% to an average of 14.4 mg/L.
The units qualify for Green Building credits under both the Leadership in Energy and Environmental Design, or LEED, rating system and the National Association of Home Builders ICC 700 National Green Building Standard.
The systems use an extended aeration process. Wastewater enters a pretreatment chamber where anaerobic bacterial action combines with the effects of gravity to precondition the waste before it flows into the aeration chamber. In that chamber, aerobic bacteria utilize the organic matter in the wastewater to convert the waste into stable substances. After aeration, the flow is directed to a clarification chamber where the biologically active material settles out.
A Bio-Static sludge return, located in the clarification chamber, then creates hydraulic currents that gently transfer settled particles back to the aeration chamber. As clarified liquids pass through a Bio-Kinetic system, they are filtered, settled and flow equalized. Effluent then passes through a biofilm reactor where the liquid is treated to a near pristine state before passing through the 500-F filter. Finally, an AT 1500 UV disinfection system reduces bacteria levels to meet strict water quality standards.
All components that contact the wastewater are made of molded plastic, stainless steel or rubber. The aerator is powered by a 1,725 rpm, 115-volt, 60 Hz, single-phase, fractional horsepower motor. The unit costs less to operate and consumes fewer kilowatt hours of electricity than most major appliances, according to the manufacturer.
