Screening is an essential process when the untreated wastewater carries exceptional amounts of solids in suspension, floating sludge or waste. It consists of a filtering process in which the untreated wastewater is passed through the screen.
The aim of this process is to get rid of matter which, due to its size, might interfere with subsequent treatments.
We offer a broad range of screens, which are classified according to the source of the effluent and their location.
Effluent pumped via a pipe
Static screen: With light up to 3 mm.
Rotary screen: With light up to 3 mm.
Worm screw screen with casing: With light from 3 to 7 mm.
Effluent carried by gravity via a concrete channel
Worm screw screen with casing: With light from 3 to 7 mm.
Step screen: With light from 3 to 7 mm.
Spillway screen qinstalled in the lateral spillways of the intake collector, to prevent discharging solids into the river bed.
