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:
“Mr. Alcott seems to have sat down for the winter. He has got Plato and other books to read. He is as large-featured and hospitable to traveling thoughts and thinkers as ever; but with the same Connecticut philosophy as ever, mingled with what is better. If he would only stand upright and toe the line!—though he were to put off several degrees of largeness, and put on a considerable degree of littleness. After all, I think we must call him particularly your man.”
—Henry David Thoreau (1817–1862)
“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)
