Abstract:
A method for waste treatment including the steps of and the associated apparatus for removing large solid waste from the influent raw sewage, transmitting the large solid waste to an incinerator, subjecting the resultant liquor to centrifuging to separate additional suspended solids therefrom, passing the additional suspended solids to the incinerator, subjecting the remaining clarified liquid to ozonation to entrap and bubble out remaining solids, to oxidize residual organic contaminants in the liquid, and to disinfect the liquid, and transmitting the solids to the incinerator. The effluent liquid resulting from ozonation can be recycled or discharged into a suitable receptacle, or it may be treated further by activated charcoal and/or reverse osmosis or similar tertiary treatment technique before recycling or discharging.
