Our fish diversion screens are used in water systems to protect fish from hydroelectric turbines and pumps, and prevent their migration into irrigation channels and canals. Hendrick’s fish screens comply with National Oceanic and Atmospheric Administration (NOAA) standards. The U.S. Fish and Wildlife Service, Army Corps of Engineers, and many state departments of fish and wildlife deploy ...

Industries use large volumes of surface water for cooling purposes or to make potable water. In the process, their (cooling) water intake structures may draw in large numbers of fish (entrainment), which can block intake screens (impingement). Unfortunately, impingement and entrainment can injure and/or kill fish. Also, impingement can reduce or stops the flow of cooling water and may result in a ...
The SWIFF screen is a horizontal cylindrical drum-shaped structure the surface of which consists of a screening element divided into deep compartments. Life-forms are collected in the deep compartments of the submerged cylinder's external surface. As the drum rotates, each compartment passes in front of the backwash suction scoop which removes the debris by reversing the flow through the ...
