Auto Bar Screen

The first unit operation generally encountered in wastewater treatment plants is screening. A screen is a device with openings, generally of uniform size, that is used to retain solids found in the influent wastewater to the treatment plant or in combined wastewater collection systems subject to overflows, especially from storm water. The principal role of screening is to remove coarse materials from the flow stream that could damage subsequent process equipment, reduce overall treatment process reliability and effectiveness, or contaminate waterways
