Intake screens, also called passive intake screens and wedge wire intake screens, are constructed of non-plugging V-shaped wires with continuous and smooth slots. Point welded onto the wedge wire support rod, intake screen supply large open area and low velocity flow through the entire screen surface.
This reduces impingement and entertainment of debris while protecting aquatic life. The slot width ranges from 1 mm to 10 mm (0.04″ to 0.4″) and 3 mm (0.12″) is the most common.
Intake screens are regarded as the first safeguard of intake system to keep fish safe and protect pumps and turbines from harmful debris. They are both efficient and environmentally safe.
