SANDFILTER EFFLUENT QUALITY WITH 40% NITROGEN REMOVAL
The American Manufacturing Company, Inc. Recirculating Sand Filter Treatment package with Recirc-Valve is based on the EPA design Standard. The system will provide enhanced effluent quality with simple maintenance and very low operational costs. The Recir-Valve requires the final discharge to be determined by the elevation of the pump station. The filter is dosed periodically by a timer. The periodic dose is continuous so filter resting is less, and maintenance events may increase but the quality potential is enhanced due to the filter being continuously active.
TANKS ARE AVAILABLE WHEREVER SEPTIC SYSTEMS ARE SOLD. Most septic tank manufacturers should already have the necessary forms that can easily be adapted to configure this system. Recirculating filters differ from single pass filters in that a Recirculating filter is much smaller and a device is required to return filtrate to the dosing tank. Coarser media can also be used because of the recirculation to provide trouble-free operation.
