Mini sewage treatment system
Abstract
Abstract This invention pertains to an efficient ecological waste sewage system which eliminates the necessity of large leaching beds or seepage pits from cesspool digested sewage effluent. It consists of the system and the apparatus for effecting the disposal of such sewage waste by preliminary digesting the raw waste material, preferably in primary and secondary digesting steps, passing the resulting liquid with fine solids therein in sequence and in controlled consecutive order to a series of steeling tanks, subjecting the liquid effluent therefrom to a simultaneous aeration-ultra violet ray sterilization treatment, and removing the water effluent therefrom as reusable water. New and novel aeration-irradiation treatment units are disclosed which provide a novel, very efficient system for effecting the elimination of sewage waste in areas where sewers are not available or where land type and quality prevent the use of present day systems for the disposal of said wastes and producing usable water therefrom.
