These semi-self-cleaning filters are designed to remove solids from water with only occasional cleaning attention. They use a wedge wire, 304 stainless steel screen set in a parabolic shape to take advantage of the Coanda effect (the tendency of a stream of fluid to follow a curved surface (if the angle is not too sharp) rather than follow a straight line in the original direction of flow). This wedge wire shape encourages solids-free water to drop between the screens and solids to be left on the surface. The solids are then pushed toward the waste trough and washed into a waste tank automatically. This filter is ideally suited for a gravity-flow system. It has a 300-micron, removable screen. Rubber couplings with clamps are included. Not recommended for use with salt water.

Operation: Slurry is gravity fed or pumped into headbox. It overflows weir, starts downward on screen. Most free fluid is stripped from bottom of stream on the 25° slope. More fluid is removed on the 35° slope, and solids roll downward, stopping on the 45° slope. With free draining material, practically all free fluid is removed in one pass. As the solids build up, water pushes them into the waste channel.

Coanda Effect: the tendency of a stream of fluid to follow a curved surface (if the angle is not too sharp) rather than follow a straight line in the original direction of flow.
