SEP 2 is a machine used for the pre-treatment of screening and grit removing of wastes from cesspool, received from a tank truck connected to the machine by a quick connection end pipe, Perrot type, DN100.
Wastewater is screened to remove larger particles, then screenings (removed particles) are washed to remove organic matters and compacted before being discharged; this washing process allows to reduce odour problems. The screened wastewater reaches the sedimentation tank, where grits settle down and then are collected until the accumulation point by a screw conveyor rotating in the tank’s bottom.
Grits are then extracted by the inclined screw conveyor. The machine consists of a receiving tank provided with a quick connection and an electromechanical ball valve; a screw screen with compacting system before the outlet zone. Connected to the acceptance tank there is the sedimentation tank, where the settling takes place, equipped with two screw conveyors to collect and remove grits.
Both the tank and the screw screen are equipped with washing systems to remove organic matters from the screenings in order to reduce odour problems.
