Wedge Wire Screens for liquid / solid separation
Wedge Wire cylinders are used as rotary screens, collectors such as screen laterals and nozzles, resin traps, in-line strainers, water intake screens, well screens, as well as many other applications involving liquid / solids separation.
Wedge Wire screen cylinders can be designed with slot openings and wires running radially on the outside surface of the screen cylinder (above left) or they can be positioned axially on the inside of the cylinder (above right)
Screen cylinders are manufactured in various diameters from 1/2" pipe size to 35". Screen cylinders (above right) can be fabricated into larger diameters. Each intersection of wedge wire and support rod is welded for strength and durability. Various wedge wire and support rod combinations can be used to produce the best screen.
Rotary Screens typically use wedge wire for the screening media. The above externally fed unit has a spiral wound wedge wire screen drum 36" OD x 120" long.
Features:
A continuous slot opening which significantly increases the available open area, thus providing a greater access to the water bearing zone.
Wedge wire which avoids clogging and ensures uninterrupted flow.
Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
