USE OF REVERSE OSMOSIS MEMBRANES TO TREAT EVAPORATOR CLEAN CONDENSATE

摘要

A method and apparatus for the treatment of the 5th Effect combined evaporator condensate generated by kraft process pulp mills. The method includes the removal from effluents of organic compounds that result in BOD, COD and toxicity by the use of reverse osmosis. Through the use of a reverse osmosis membrane system (30, 56) there is provided a simple, economical and efficient treatment process for clean evaporator condensate, and in particular the 5th Effect combined evaporator condensate.
