Abstract

A wastewater treatment reactor includes an upper chamber 4 biomass therein and a lower chamber including a combination filtering/aerating unit 6 having a gas inlet 9 and a discharge outlet 10 for purified water. In operation, wastewater enters the upper reactor chamber via delivery pipe 12 and is mixed with biomass. During a filtering mode, the wastewater then enters the porous hollow body 7 defining a membrane unit 6 and is filtered thereby. In an aerating mode, gas travels across the membrane in an opposite direction freeing the membrane of biomass lodged therein. A heat exchanger 16 can be provided for exchanging heat energy between the wastewater input and the purified water output. A control device for regulating gas flow, wastewater flow, and pH may also be provided including pressure, pH and oxygen content measurement. A channel 7a may be provided for adding a cleaning medium and also an absorbent reactor 13 for treating waste air.

Dependent claims

A waste water treatment system for the aerobic microbiological treatment of waste water comprising:

(a) a reactor having an upper and a lower reactor chamber, said upper reactor chamber containing biomass;
and
(b) a filtering and aerating unit forming said lower reactor chamber and comprising an input port connected to a gas source, a discharge outlet for purified water, and at least one porous hollow body defining a membrane and including a hollow chamber communicating with said input port and said discharge outlet;
wherein waste water to be purified is supplied via a waste water supply pipe to said upper reactor chamber and mixed with said biomass,
and wherein in a filtering process, waste water then enters said filtering and aerating unit, travels across said membrane and exits as purified water via said hollow chamber and said discharge outlet;
and in an aeration process, gas supplied to said input port enters said hollow chamber, travels across said membrane and flows into said upper reactor chamber.
