Product Description
This kind of 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.
