A bar screen is a mechanical filter used to remove large objects, such as rags and plastics, from wastewater.[1] It is part of the primary filtration flow and typically is the first, or preliminary, level of filtration, being installed at the influent to a wastewater treatment plant. They typically consist of a series of vertical steel bars spaced between 1 and 3 inches apart.[2]
Bar screens come in many designs. Some employ automatic cleaning mechanisms using electric motors and chains, some must be cleaned manually by means of a heavy rake. Items removed from the influent are called screenings and are collected in dumpsters and disposed of in landfills.[1] As a bar screen collects objects, the water level will rise, and so they must be cleared regularly to prevent overflow.[3]
