SS304 100m3/H Tank Mounted Waste Water Screw Screens
The screen is mounted in open channels or a tank with an incline of up to 45°. The slotted or perforated mesh is mounted in the bottom of the screen. Particles with sizes larger than the filtering mesh openings are collected on the mesh surface as wastewater flows through the mesh. The non-axial spiral with varied pitch screw is designated to remove waste from the filtering mesh, and transports material to the discharge zone on top of the screen. For better filtering mesh cleaning, the screw is equipped with a peripheral brush. The screen includes waste washing and compacting zones at the top of the screen before the discharge zone.
Screw Screen Technical Parameter
Screw Screen Operating Principle
Particles that are collected on the filtering mesh of the screen are moved up along the barrel by a rotating spiral. At the same time, the mesh is thoroughly cleaned by peripheral brushes.
Waste compacting is achieved by the decreasing screw pitch. The organic contaminants are flushed from the waste by spray water from washing nozzles on the top of the barrel. Washing water and water pressed from the solid material is taken to the channel upstream of the screen by a pipeline. Washed and drained screenings are discharged into a waste bin at the discharge zone. The screen operation periodicity depends on the equipment automation scheme.

Screw Screen Function
The process starts on the screen that holds back solids only. The internal part of the screen is continuously cleaned by brushes fixed on the outside diameter of the flighting. As the water runs through the screen the shaftless spiral conveys the solids up towards the compaction module where the material is further de-watered. Depending on the material properties, screenings can be reduced by more than 50% of their original volume.
We offer a complete line of in channel or in-tank screening systems. Each unit utilizes a perforated plate or v-wire screen section to effectively remove unwanted solids and debris from the influent. The screenings are transported via a shaftless conveyor to the compactor and washing zone, where they are cleaned, dewatered, then finally discarded into a receptacle or optional bagging system. Screens can be installed in-channel or in a self-contained stainless steel tank.
