Abstract

A self-contained system for treating and recycling waste water, particularly for a toilet cubicle in a railway carriage or the like. Waste water from a toilet pan (1) and wash basin (2) is treated in an aerated membrane bioreactor (6). The permeate front the bioreactor is exposed to ozone and ultraviolet light in a tank (27) from which a first stream is taken and reused for flushing the toilet. A second stream from the permeate tank is treated to a higher (potable) standard of purity by successive stages of reverse osmosis (45) and ion exchange (47) and reused for hand washing.
