WATER TREATMENT APPARATUS Russian patent published in 2013 - IPC C02F1/44 B01D61/10 B01D63/16 C02F103/04 

FIELD: process engineering.

SUBSTANCE: invention may be used for removal of insoluble admixtures from fluids. Proposed apparatus consists of tank 1, rectangular in plan, equipped with feed and discharge branch pipes 2, 3, sediment collector composed of drive and driven shafts 4 running in bearings. Reel of permeable film is fitted on driven shaft 4. free end 6 of said reel is arranged on surface of permeable web 7 making closed chamber with walls and bottom and secured to driven shaft 8. Permeable film reel, a membrane, is fitted on driven shaft 4. Suction chamber of pump 12 is connected to closed chamber discharge branch pipe 3. In operation, film with deposited slime is reeled on drive shaft 8. In reeling and keeping the reel above water surface, sediment is dehydrated. After dehydration, film reel with sediment is directed to range for solid wastes. In case the tank is equipped with idle shaft 5, driven and idle shafts 4, 5 are located under water level while drive shaft 8 is located above water surface. Note that membrane edge is laid under idle shaft 5 and secured to drive shaft 8.

EFFECT: higher efficiency of treatment, extraction of dehydrated admixtures.
