A traveling screen is a type of water filtration device that has a continuously moving mesh screen that is used to catch and remove debris. This type of device is usually found in water intake systems for water and wastewater treatment plants. Screening is considered the first step in conventional sewage treatment processes. Screening is also used in water intakes in power plants. Traveling screens can be used to catch leaves, sticks, grass, jellyfish, trash, green mussels, shells, hydroids, seaweed, and plastics.
Famous quotes containing the words traveling and/or screen:
“We joined long wagon trains moving south; we met hundreds of wagons going north; the roads east and west were crawling lines of families traveling under canvas, looking for work, for another foothold somewhere on the land.... The country was ruined, the whole world was ruined; nothing like this had ever happened before. There was no hope, but everyone felt the courage of despair.”
—Rose Wilder Lane (1886–1968)
“Every obstruction of the course of justice,—is a door opened to betray society, and bereave us of those blessings which it has in view.... It is a strange way of doing honour to God, to screen actions which are a disgrace to humanity.”
—Laurence Sterne (1713–1768)
