Abstract

A method and apparatus for purification of waste water containing ions of heavy metals. With the use of filters (5, 6, 7) operating on the principe of reversed osmosis the waste water is purified and the resultant concentrate is a solution of salts which may be collected (10) for continued processing to recover the metals therein.
