A system and method for treating an aqueous effluent having organic material. The system comprises a single cell reactor having an injector for injecting an oxidizing gas into the reactor. Disposed downstream from the injector is an immersed membrane filtration device for filtering the effluent contained or passing through the reactor. Disposed between the membrane filtration device and the injector for directing an oxidizing gas into the reactor, is a bed of catalyst material. Preferably the oxidizing gas injector injects an oxidizing gas in a direction co-currently the direction of the effluent being treated. The bed of catalyst material is capable of catalyzing the oxidation of the organic material in the effluent or absorbing the organic material.

Installation and method for the purification of an aqueous effluent by means of oxidation and membrane filtration

A method of removing phosphonates from water includes directing the water into a first settling zone. The water is then directed to a membrane filtration zone and is filtered therein to produce a concentrate containing phosphonates. The concentrate containing phosphonates is then contacted with sludge such that at least some of the phosphonates in the concentrate are adsorbed onto the sludge. Flocculant is added to the sludge and the concentrate to form a floc-mixture which is directed to a second settling zone to form treated concentrate.

Membrane station waste treatment process

A system and method is provided for removing organic matter from water. The method includes contacting the water with a powdered material with an anionic or cationic surface charge and having a particle size of between 0.1 mm and 2 mm. The powdered material is a modified product of natural origin. The system and method also provides for the regeneration of the powdered material in situ and reused.
