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)
“The End?”
—Theodore Simonson. Irvin S. Yeaworth, Jr.. End title card, The Blob, printed on screen at the end of the movie (1958)
