ANALYSIS OF THE CAPABILITIES OF THE FILTERING FISH PROTECTION DEVICE WITH HORIZONTAL PLACEMENT OF CASSETTES

Problem statement. In accordance with the code of rules (SP 101.13330.2012), use fish protection devices a filter screen and flushing system applies to water intake facilities in various placement conditions, this regard, it is relevant expand possibilities using cassettes at shallow depths source.
 Results. A methodology has been developed substantiate filler parameters horizontal cassette form plastic balls their distribution along its length, as well preliminary assessment uniformity flow rates over area cassette.
 Conclusions. To improve operational characteristics fish-protective device conditions sampling depths, instead basic design vertical layout, horizontally positioned surface self-washing effect recommended, which made (with positive buoyancy) used there free space for movement. On basis hydraulic calculation, method estimation filtration such developed. ensure uniform length cassette, recommended different diameters. Evaluation working allowed us obtain pattern changes diameter so specific example, calculated varied from 8 mm, suction nozzle, 40 mm end cassette. The technique can be calculate devices.
