APPARATUS AND METHOD FOR TREATMENT OF WATER

摘要

A method for treating raw contaminated water includes a housing (21) including a separator element. The separator element includes a membrane which prevents flow of contaminants and allows flow of water such that raw water passing over the membrane passes through the membrane while contaminants are excluded. Contaminants are extracted in a concentration chamber (31) forming a return stream (41), at least part of which is returned to the housing to pass over the separator element again. In one embodiment, gas is injected into the water prior to entering the concentration chamber.
