€7.600,00 – €10.000,00Price range: €7.600,00 through €10.000,00 taxes not included
Screw conveyor screen (AquaTSF) for the fine screening of urban and industrial wastewater, for channel installation in concrete. The shaftless screw, with brush cleaning, captures the solids retained by the mesh, lifts, drains and compacts them and discharges them dewatered. Made of AISI 304 L / 316 L stainless steel, with a configurable mesh opening from 2 to 10 mm.
Lead time: to be confirmed, depending on the equipment and component stock.
Shipping included in the price, excluding unloading at destination. For large equipment, please ask about transport and unloading conditions.

Description
The INZA screw screen (AquaTSF) is a fine-screening screw-conveyor unit designed to extract and convey the solid residues in urban and industrial wastewater whose size exceeds the mesh opening. It is installed directly in a concrete channel at a 35° angle: the water passes through the screw and the auger lifts the solids to discharge them, drained and compacted, into a container. It reduces the solids load reaching downstream equipment and improves overall treatment efficiency.
