Bar screen GPSA

for wastewater treatmentcoarse screening

The sub-vertical flat screen with alternate motion is installed on medium and large size civil or industrial treatment plants and can meet macro-screening requirements. It consists of a sturdy frame in structural steel, a bar assembly, a pendulum type bucket integral with a trolley, a trolley driving system moved by a couple of chains, a bucket cleaner for the screenings discharge and a gear motor. The screened material deposited on the screen bars is removed by the bucket during its upward stroke and thrown out of the cleaner to an established distance from the top limit switch.
