Answer 2

The main function of a bar screen is to separate the large objects or particles from the water to be treated. These bar screens are used as a primary filtration method in the Waste water treatment plants.

The Bar screen is a kind of mechanical filter and is used in the waste water treatment plant to remove the bigger and larger impurities like plastics or used cups, etc. After removal of larger impurities, it becomes easy to treat the water to get rid of the smaller impurities or impurities mixed in water with the help of chemical treatment.
