EPCO Australia Wastewater Treatment Screens

Inclined Bar Screen

The EPCO Australia inclined mechanically raked bar screen features robust construction using quality materials and components throughout, with an emphasis on long term durability in the corrosive atmosphere which exists around the inlet structure of a biological waste water treatment facility.


In operation, sewage flows through the inclined screen, approaching from the upstream side and after passing through the screen, departing on the downstream side. The screen is periodically raked by a mechanised comb system which is actuated either by level switches mounted in the channel upstream of the screen or by time clock. The screenings collected by the moving combs are removed by a doctor blade at the top of the comb travel.

The moving combs are suspended between two endless side chains which are driven through a head shaft and sprockets. The gear motor and moving comb system is protected from damage by a torque overload coupling with a micro switch.

The screenings removed by the doctor blade drop onto a skid plate which transports them down to a container, belt conveyor or sluice pipe.

Curved Bar Screen

The EPCO Australia curved bar screen features robust construction using quality materials and components throughout, with an emphasis on long term durability in the corrosive atmosphere which exists around the inlet structure of a biological waste water treatment facility.

In operation, sewage flows though the curved screen, approaching from the upstream side and after passing through the screen, departing on the downstream side. The screen is periodically raked by a mechanised comb which is actuated either by level switches mounted in the channel upstream of the screen or by time clock.

The screenings collected by the moving comb are cleaned from the comb by a doctor blade at the top of the comb travel. The screenings removed by the doctor blade drop onto a skid plate which transports the screening down to a container, belt conveyor or sluice pipe. The curved screen illustrated is suitable for 2-3 metre deep channels up to 1.5-2 metre wide.
