EFFLUENTS INDUSTRIAL EFFLUENTS TREATMENT PLANT Russian patent published in 2014 - IPC C02F1/00 B01D29/00 B01D29/66 

FIELD: process engineering.

SUBSTANCE: invention may be used for biological cleaning of industrial effluents. Proposed plant comprises vertical housing composed of two parts, i.e. top cylindrical part 1 and bottom conical part 2. Said cylindrical part 1 houses filtration element 15 composed of hollow perforated carcass. Perforated carcass is composed of truncated cone with chamfered and staggered holes 26. Outer surface of filtration element 15 is furnished with filtration element 17. Top section of filtration element 15 is rigidly secured to cover 13. Cover 13 has two through holes 27, 28 accommodating electric valves 31 for feeding of compressed air and water. Slime accumulation tank 32 is rigidly connected with filer housing bottom conical part 2. Top part of slime accumulation tank 32 has hole 33 to accommodate pipe 34 connected with effluents feed pump inlet 9. Bottom part of slime accumulation tank 32 has hole 38 to accommodate tangential slime discharge pipe 39 with pipeline 41 to discharge slime into slime accumulation tank 42. Said slime accumulation tank 32 has hole 43 communicated via pipeline 46 with slime feed pump inlet 47. Said slime accumulation tank 32 has filtrate discharge pipe 19 with filtrate accumulation tank 18 arranged there behind.

EFFECT: higher efficiency, longer life.
