System for treating sewage or other fluids

摘要

A method and device for complete treatment of septic tank effluent or other contaminated water by contriving for it to flow in an ultra-thin film over a surface treatment medium such as fabric or sand. It provides diffusive aeration, biological reaction and physical filtration on a molecular scale. The device transfers contaminated water, or other liquid, from a container to a final collector completely purifying the liquid in the process. The purified effluent can then be reused for household, industrial, irrigation or other uses, or disposed of as normal surface run-off in streams or lakes. To increase efficiency, said container encloses a progressively more finely pored media precisely situated with effluent seeping gradually through progressively finer pores to provide uniquely effective pretreatment.
