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 Features:

• Available in Stainless Steel 304 or Stainless Steel 316.
• Throughput Flow rates up to 1,000 m3/hr.
• Optional Wedge Wire Screen Basket or Perforated Plate in Various Mesh Sizes
• No outlet end bearing, no intermediate hanger bearings.
• Solids extraction of up to 1.1 m3/hr.
• Shaftless sprial screw conveyor prevents jamming or locking up even with fibrous materials.
• Optional Screen and Pipe Washing System.
• Low investment and maintenance costs.

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.

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.
