Industrial water filters use V-shaped wires to clean themselves

Most filters eventually choke on the very debris they are meant to catch, but the wedge wire screen uses a clever geometric trick to stay clean. These industrial filters are composed of V-shaped stainless steel wires welded onto support rods. Because the widest part of the 'V' faces the incoming water, any particle small enough to enter the 0.1-millimeter slot will pass through entirely rather than getting wedged halfway, a design that resists clogging three times better than traditional mesh.
