Abstract
Abstract A system for treating sewage comprising a plurality of independent interconnecting stations which include feeding raw sewage through a slurrier where waste solids are broken down into small particles and fed to a foam generator which generates the slurry into an odorless foam. This foam is pumped to a drain facility where the foam is accumulated and the effluent separated therefrom via a fine wire mesh continuous conveyor through which the effluent is drained or filtered leaving a mat-like residue which is removed from the conveyor into containers. The effluent drains into a reservoir including aerator means which aerate the effluent, after which it is fed into a drain.

Claim 3
Dependent Claim
128 words
A sewage disposal system as in claim 1 wherein said drain means including an accumulating chamber connected to the second foam output means; separator means comprising a continous conveyor of fine mesh material disposed in spaced, substantially transverse, communicating relation to the output of said drain means, said conveyor oriented and configured to dispose its outer and inner surface to the dying effects of the atmosphere circulating about it, whereby the discharge fRom said output of said drain means is separated into a dried, mat-like product and effluent; and a reservoir means disposed in spaced, substantially transverse, communicating relation to said separator means to collect said effluent, said reservoir means including said aerator means to purify said effluent and a reservoir drain to dispose of the purified effluent.
Claim 4
Dependent Claim
66 words
A sewage disposal system as in claim 1 wherein said blender means comprises input means interconnected in communicating relation to a source of solids, said flow control means disposed in said system relative to said slurrier means, foaming means, blender means and drain means such that solids may be selectively added to the output of said slurrier means and said foaming means through said blender means.
Claim 5
Dependent Claim
142 words
A process for treating sewage of solid and liquid form, said process comprising sequentially: a. slurrying the sewage; b. separating out solids not effectively broken up by said slurrying; c. feeding said separated solids into a blender; d. feeding additional solids into the same blender; e. feeding the resultant slurry from slurrying the sewage into a foam generator; f. foaming said slurry; g. blending said separated solid, said additional solids and the resultant foam from the foam generator; h. draining said foam through a separator means; i. collecting said solids present in said foam on a separator means; j. drying said solids; k. conveying said dried solids to a loading station; l. collecting an effluent liquid passing through said separator means in a reservoir means; m. aerating said effluent in said reservoir means; and n. discharging said aerated effluent through a discharge.
