Answer:

A place where wastewater from houses and other building like industrial area is brought for processing is called wastewater treatment plant. Waste-water treatment plant can be written as WWTP. The wastewater treatment plant is also called sewage treatment plant. In a wastewater treatment plant, bar screen removes large solid components from water. The wastewater is allowed to pass through bar screen so that large solid components like rags, napkins, sticks, cans, plastic bags, polythene etc. present in wastewater can then be removed.
