New Delaware wastewater treatment system approved by DNREC

Anua’s new Platinum Submerged Aerated Filter system received approval from the Delaware Department of Natural Resources and Environmental Control.

Greensboro, N.C., Oct. 5, 2012 -- Anua’s new Platinum Submerged Aerated Filter (SAF) system received approval from the Delaware Department of Natural Resources and Environmental Control (DNREC). DNREC accepted the European EN 12566-3 protocol, verifying that Platinum will provide an effluent quality not exceeding 30 mg/l of BOD and 30 mg/l of TSS and a minimum 50 percent reduction in Total Nitrogen (TN).

According to Colin Bishop, director of sales and government relations for Anua, “The Platinum approval will provide the home and business owners of Delaware a robust treatment system with a small-footprint. Platinum is an affordable option for reducing nitrogen and for protecting Delaware’s critical water resources, including the Chesapeake Bay.”

Key product benefits include: underground installation (including blower and low-profile access covers), a submerged aerated filter with no by-pass of media, integrated biomass return from a clarifier to a primary tank and a small footprint for environmentally sensitive installation in residential, small neighborhood and commercial applications.

The Platinum system for individual residential use comes fully assembled for immediate below-ground installation by authorized installers. The system is highly efficient and virtually silent -- the only moving part is a small air-delivery system -- and its lower maintenance and power consumption needs mean lower total costs for homeowners compared to other aeration systems. It also includes a single or two-stage primary settlement tank, rare in a plant this size.

Platinum’s unique design and three-step treatment system feature a submerged aerated filter that reduces the level of biological oxygen demand (BOD) and total suspended solids (TSS) in the effluent to secondary standards. Coupled with a peat fiber biofilter, the treatment will achieve a 5:5 mg/I BOD:TSS standard and significant pathogen reduction.

The Platinum wastewater treatment system for small community and commercial use offers numerous options for larger populations, and it’s perfect for small housing developments, apartments, restaurants and hotels, RV and mobile home parks and schools or nursing homes. Below-ground installation does not take up valuable yard space or leave unsightly equipment exposed, so there is nominal visual impact on the surrounding area. With the same cost, maintenance and installation benefits as the residential system, Platinum for small communities and commercial use can be modified to conform to strict regulatory standards for enhanced BOD and TSS removal, nutrient and pathogen reduction. The Platinum wastewater treatment system is the newest product from Anua, a leading designer, manufacturer and supplier of wastewater treatment systems in the U.S. for nearly 20 years.
