Traveling Screen

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:

    It is impossible for a stranger traveling through the United States to tell from the appearance of the people or the country whether he is in Toledo, Ohio, or Portland, Oregon. Ninety million Americans cut their hair in the same way, eat each morning exactly the same breakfast, tie up the small girls’ curls with precisely the same kind of ribbon fashioned into bows exactly alike; and in every way all try to look and act as much like all the others as they can.
    Alfred Harmsworth, Lord Northcliffe (1865–1922)

    The screen of supreme good fortune curved his absolute smile into a celestial scream.
    John Ashbery (b. 1927)
