METHOD OF INCREASING FLOW OF WATER FROM SETTLING TANK OF PROCESS OF TREATING TAR SANDS THROUGH MEMBRANE SEPARATION AND WATER TREATMENT SYSTEM Russian patent published in 2013 - IPC C02F1/44 C02F1/52 C02F1/56 C02F9/00 C02F101/32 C02F103/10 C02F1/54 B01D61/00 

Abstract RU 2487085 C9

FIELD: chemistry.

SUBSTANCE: method includes steps (a) of treating water with an effective amount of one or more water-soluble cationic polymers, amphoteric polymers, zwitterionic polymers or combinations thereof; (b) passing the treated water through a membrane separation system; and (c) optionally passing filtrate from step (b) through an additional membrane separation system.

EFFECT: high efficiency and simplification of the process.
