Self-Cleaning Shallow Water Screen

Self-Cleaning Shallow Water Screen IRRIGATION Miscellaneous Anyone who depends on river or canal water for irrigation will be interested in this new water-driven self-cleaning screen that’s designed to work in water as shallow as 4 in “There’s nothing else on the market that can pump out of such shallow water and also clean itself at the same time ” says inventor Bob Wietharn The Riverscreen floats on four pontoons and draws water from more than 35 sq ft of screening area Water is delivered through a pipe available in 4 6 8 10 or 12-in dia with 150 gpm to 4 000 gpm capacity A screened rotating drum measuring 32 by 48 in is supported by an aluminum frame that mounts on the pontoons Flowing water moves past a series of paddles which force the drum to rotate and self-clean via a stainless steel mesh screen As the screen rotates with the drum it goes by a series of jets which dislodge anything that sticks to the screen An optional electric power drive can be added for use in slow-moving water tailwater return pits and manure lagoons Also optional is a galvanized lift boom that lets one person quickly swing out and gently lower the Riverscreen to the water surface “It draws water that’s only 2 in below the surface which is usually the cleanest water ” says Wietharn “It draws water from seven times the area of the suction line You can draw from shallower water if you’re pulling it from a bigger area because the the water moves more slowly ” Contact: FARM SHOW Followup Riverscreen Inc 1925 Kiowa Road Clay Center Kansas 67432 ph 785 632-5452; email: Riverscreen@kansas net; website: www riverscreen com
