Screw sieve
The vertical rotary screw sieve is made in stainless steel ASI304. To facilitate its installation, it is installed in an FRP tank with no need for a concrete channel. The sieve separates the solids present in the wastewater.
The water flows through the mesh and the solids retained by the mesh are lifted up by an Archimedes worm screw and finally deposited in a bag. The solids reduction volume is about 30%.
