Abstract
An on-site waste water treatment system is disclosed suitable for domestic or other sewage. After the initial separation of the gravity settleable solids in a treatment tank, the effluent is conveyed to a recirculation/dosing tank. The recirculation/dosing tank has three level indicators which transmit information to the system controller. The low level indicator provides enough waste water to dose a media bed and dilute effluent from the treatment tank. While the low level indicator is activated, the waste water will circulate through a disc filter to a recirculating media bed. From the media bed, the effluent is returned to the recirculation/dosing tank, the waste water flows from the treatment tank to the recirculation/dosing tank and activates the second level indicator, enabling the system to pass the combined effluent through a disc filter to a final disposal field. If the second level indicator has been disengaged for a sufficient period of time, the effluent passes through the disc filter and recirculating media bed for a set number of times before the effluent is conveyed through the disc filter to the final disposal field.
