SPU is a machine used for the pre- treatment of of wastes from cesspool, received from a tank truck connected to the machine by a quick connection pipe (Perrot) DN100.
It can combines up to three processes at a time: screening; grit removing; grease removing.
The screened wastewater reaches the sedimentation tank, where grits settle down and then are collected until the accumulation pit by a screw conveyor rotating in at the tank’s bottom.
Grits are extracted by the inclined screw conveyor.
The inlet valve is electrically controller.
A built-in stone trap avoids big stone/particles to reach the screen.
Screws: High strength carbon steel or stainless steel AISI 304 / 316
Structure: Stainless steel AISI 304 / 316
Screen Basket: Perforated sheet with Ф=6mm holes
Trough Protection: Bolted stainless steel wearing bars.
– Low maintenance required
– Easy to install
– Screenings’ weight reduction and cleaning
– Grease removing
– No construction works required
