Description of Technology

Descriptions for proprietary technologies are from the Massachusetts DEP Approval Letters for the technology.

PERC-RITE Drip Dispersal System, Models QM(WD), ASD-15, ASD-25 & ASD-40

The System is a pressure distributed subsurface wastewater drip dispersal (disposal) system that replaces a conventional soil absorption system (SAS). The System is designed to distribute septic tank or secondary effluent and pressure discharge it at a depth of at least 6 inches below finished grade. The System includes a pump, control panel, a filter module/hydraulic unit and drip dispersal zone(s) with drip tubing incorporating discharge emitters. The dispersal zone(s) include small diameter flexible polyethylene tubing with pressure compensating emitters. The emitters operate on a pressure differential across the emitter, with wastewater discharged in small doses. Dispersal field dosing is timed and controlled electronically to provide pre-programmed volumes of effluent for discharge to each dispersal zone(s). The System allows periodic backwashing of the filtration system and forward-flushing of the dispersal tubing with the flush/backwash effluent conveyed by return line to the septic tank. The System may include single (the QM/WD model) or two-stage (the ASD models) automatic backwashing disc filters within the filter module and air vents in each dispersal zone. Each zone shall have air release valves at the high points of manifolds and check valves on each return manifold in multi-zone systems. The System shall be equipped with a totalizing flow meter.
