Stainless steel wedge wire acreens are welded at each intersection of V-shaped surface wire and support rod for optimum structural strength.
The precisely spaced narrow slot openings between V-shaped wire only allow two-point particle contact. The larger solids accumulate on the solid surface to produce a "cake" that provides filtration for finer particulate. Finer particles that pass through the cake do not get stuck in the slots.
Wedge wire filters offer almost endless cleanability via backwashing. By reversing the flow, the cake and filtered particles are removed.
