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)
“We like the chase better than the quarry.... And those who philosophize on the matter, and who think men unreasonable for spending a whole day in chasing a hare which they would not have bought, scarce know our nature. The hare in itself would not screen us from the sight of death and calamities; but the chase, which turns away our attention from these, does screen us.”
—Blaise Pascal (1623–1662)
