METHOD OF INCREASING FLOW OF WATER FROM SETTLING TANK OF PROCESS OF TREATING TAR SANDS THROUGH MEMBRANE SEPARATION AND WATER TREATMENT SYSTEM

摘要

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.;16 cl, 3 dwg, 1 tbl, 3 ex
