Abstract
A component filter device which is added to a new or existing multi-chamber septic tank to filter the effluent of the septic tank to improve the quality of the water entering a method of dispersal. The device uses a spiral wound membrane filter to filter the effluent. The membrane filter contains open channel spacers to channel the bubbles which scour the membrane leaves. An air lift pump is used to pump permeate. A three-way actuator valve directs the airflow to either the pump or to a bubble diffuser. A two-way actuator valve directs the flow of permeate. A low water indicator directs the operation of the device. The device uses bubble scouring and back washing to clean the membrane leaves. A blower, two actuator valves and a low water indicator are the only moving parts of the device.
