Package Treatment Plant

The package treatment plant combines screening, grit and grease removal within a single compact unit. This space and cost-saving design is used for the pre-treatment of sewage from cesspools and Imhoff tanks.

Raw sewage enters the tank and first passes through a Vee-Wire^® or perforated plate screw screen which captures mostly inorganic solids greater than the screen opening. These solids are compacted in the screw screen and discharged while the screened sewage flows through to a grit chamber. In this chamber, the flow velocity causes the grit to settle. A longitudinal screw conveyor carries over the settled grit to a grit classifier from where it is extracted and discharged using a third screw. A built in aeration system causes the oil and grease to float and be removed over a weir through a separate storage zone built into the tank. The process is fully automated and controlled through a PLC.

The packaged treatment plant is suited to handle flow rates up to 44,000 gpm / 10,000 m³/hr.
