<p>A waste water treatment apparatus (1) for effluent containing biodegradable solids having a first chamber (3) for retaining the solids while allowing liquid effluents to pass therethrough to a filtering chamber (11) which contains a filter medium (13, 32). The solids (biomass) are digested by worms and/or bacteria in the first chamber (3) and the liquid effluents from the first chamber (3) are treated by bacteria which is in the filter medium (13, 32). The thus purified water passes into the holding chamber (14) from where it is used for gardening or as required.</p> |
