C.M. Kristman Septic Services does a brisk business installing onsite treatment systems in Chester County, Pennsylvania, about half an hour west of Philadelphia.

When poorly drained or other restrictive sites call for advanced treatment of septic tank effluent, owner Charlie Kristman chooses aerobic treatment units from Norweco. 

Norweco offers a variety of ATUs for residential and small business applications. The Singulair R3 water reuse system reduces water consumption, reuses treated effluent and recycles water. The system is designed to operate quietly, efficiently and automatically to treat tank effluent to levels that enable restricted indoor and unrestricted outdoor use.  

The company says the system exceeds the effluent requirements of NSF/ANSI Standards 40, 245 and 350. Effluent from the units averages 5.0 mg/L CBOD, 4.6 mg/L TSS, 2.3 NTU turbidity and 2 MPN/100 ml coliform bacteria. It also reduces total nitrogen by 66% to an average of 14.4 mg/L.

The Singulair R3 qualifies for Green Building credits under both the Leadership in Energy and Environmental Design (LEED) rating system and the National Association of Home Builders (NAHB) ICC 700 National Green Building standard. The system is encased in a watertight polyethylene tank and is suitable for new or retrofit applications.

The Singulair Green tank has support ribs and arch shape for durability. The unit delivers pretreatment, aeration, clarification, filtration, flow equalization, optional disinfection and dechlorination in one unit. Designed for domestic flows up to 600 gpd, the unit is certified to NSF Standard 40. Underwriters Laboratories (UL) and the Canadian Standards Association (CSA) have certified or listed all electro-mechanical equipment and components for safety, reliability and quality.

The Hydro-Kinetic Green treatment system incorporates advanced aerobic treatment in a durable and watertight polyethylene enclosure. It includes the company’s Bio-Film Reactor technology to produce high-quality effluent, according to the maker. The system is designed to meet strict local regulations in areas where excessive nitrogen is a concern.

The treatment process reduces nitrogen to less than 10 mg/L, lower than the U.S. Environmental Protection Agency standard for drinking water. The system meets or exceeds regulatory standards and is certified and listed by NSF International to Standards 40 and 245. During CAN/BNQ 3680-600 and NQ 3680-910 tests, the system achieved effluent results of 3 mg/L CBOD, 2 mg/L TSS, and 67% reduction of total nitrogen.

It also achieved an effluent quality of 2,200 CFU/100 ml fecal coliform without UV disinfection and 2 CFU/100 ml fecal coliform with UV disinfection. With the addition of the company’s Phos-4-Fade filter, it achieves 0.14 mg/L effluent total phosphorus. Treatment process quality is protected by a non-mechanical, demand-use flow equalization device and the company’s Bio-Film Reactor.
