ABSTRACT:
A water treatment process comprising: (a) providing bioactive material in waste water, the bioactive material containing microorganisms capable of removing one or more impurities from the waste water, wherein at least 40% by volume of said bioactive material in said waste water is in granular form; and (b) passing a portion of the waste water through a membrane separator, whereby the membrane separator prevents the bioactive material from passing therethrough.
