Wholesale Fine Screens – Shaftless Screw Press Filter Screen for Wastewater Treatment – Holly Detail:

Product Description

The SCREW SCREEN offers the waste water filtration and the transport of the effluents for the stocking, in a practical and efficient package. The SCREW SCREEN COMPACTOR is the more complete variant, with a compactor zone next to the discharge, which allows an important reduction in weight and volume of filtered waste (up to 50% less). The machine can be installed inclined (between 35 ° and 45 ° depending on the needs) into a concrete channel or in a stainless steel tank to receive the wastewaters from a fixed pipe.
The filtration zone for all the variant of the SCREW SCREEN is made up by a holed sheet (circular holes from 1 to 6mm) which filters the wastewater holding back the waste. Into this zone, the shaftless screw is equipped with brushes for the cleaning of the filtration. There is also a washing system activatable by a manual valve or through solenoid valve (optional).
The transport zone is composed by an auger and the continuation of the shaftless screw. The screw, when activated by gear motor, rotates on itself picking and transporting waste until the discharge outlet.

Product Features

The process starts in 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 to the material properties, screenings can be reduced by more than 50% of their original volume.
