Screw Screen in Tank
Model SSB-mK
This packaged screw screen provides primary treatment for untreated sewage.
The SSB-mK screw screen is equipped with a stainless steel tank to allow installation where a concrete channel is not available. The tank is complete with flanged inlet and outlet pipe stubs.
The tank can be fitted with an optional bypass chamber (as contingency if the main screen overflows) fitted with a manually cleaned bar screen. The system includes screening compaction at the end of the conveying section of the screw.
Due to small footprint, minimal civil works required, and ease of installation, the Screw Screen in Tank offers a simple and low cost solution for small wastewater treatment applications and septage receival facilities.
