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.

Screening is considered the first step in conventional sewage treatment processes.

Screening is also used in cooling water intakes in steam electric power plants, hydroelectric generators, petroleum refineries, and chemical plants.

Traveling screens are used to divert fish, shellfish and other aquatic species, and debris including leaves, sticks, and trash; for the purpose of preventing damage to a facility's treatment or cooling system.
