Claim 3

The system of claim 3 further comprising: a. substantially cylindrical filtering means positioned in said upper section of said treatment tank, b. said transferring means communicating with the interior of said cylindrical filter and said lower section to transfer said effluent from said upper to said lower section.

Claim 4

The system of claim 4 wherein: a. a plurality of walls sub-divided said lower sectiOn into a plurality of subsections, b. openings through said walls placing said subsections in serial communication, c. an upstream one of said subsections communicating with the interior of said filter, and d. a downstream one of said subsections communicating with said discharging means.

Claim 5

The system of claim 1 wherein: a) said separating means comprises a plurality of baffles subdividing said upper section into a plurality of settling chambers.

Claim 6

The system of claim 1 wherein said ejecting means comprises: a. a supply reservoir for said additive, b. an aspirator mounted within said cylindrical filter, and c. conduit means interconnecting said reservoir and said aspirator for withdrawing a charge of said additive from said reservoir in response to effluent flow in said interior of said filter around said aspirator.

Claim 7

The system of claim 1 wherein: a. said separating means comprises screen means interposed between said filtering means and said macerating and pumping means.

Claim 8

The system of claim 8 wherein: a. said screen means comprises a plurality of screens, b. said screens having progressively smaller openings therethrough from said macerating and pumping means to said filter means.

Claim 9

The system of claim 8 further comprising: a. spray means directed at an upstream one of said screen means and communicating with said macerating and pumping means to direct said slurry against said screen means.

Claim 10

The system of claim 1 wherein said means for ejecting a purifying additive into said treatment tank comprises: a. a supply reservoir, and b. means for feeding additive from said supply reservior to said lower section of said treatment tank.

Claim 11

The system of claim 11 wherein said feeding means comprises: a. a holding tank, b. means for transferring said additive from said reservoir to said holding tank, and c. a conduit interconnecting said holding tank and said lower section of said treatment tank.

Claim 12

The system of claim 12 further comprising: a. a one way valve in said conduit allowing flow from said holding tank to said lower section of said treatment tank, and b. a one way vent valve in said treatment tank venting inwardly into said tank.

Claim 13

A waste treatment system comprising: a. a bowl for collecting liquid and solid wastes, b. means for admitting a flushing liquid to said bowl to flush said wastes therefrom, c. a macerator pump for receiving said wastes and said flushing liquid, macerating them into a pumpable slurry and pumping said slurry downstream thereof, d. a treatment tank downstream of said macerator pump, e. a substantially horizontal wall dividing said treatment tank into upper and lower chambers, f. a cylindrical filter mounted in said upper chamber, g. a plurality of screens positioned about said filter in encircling relationship thereto, h. a spray pipe having an inlet in communication with said macerator pump to receive said slurry therefrom and a plurality of outlets therefrom in said treatment tank directed at the outer surface of the outermost of said encircling screens, i. a plurality of substantially vertical walls dividing said lower section of said treatment tank into a plurality of serially interconnected, mixing subsections, j. means defining an opening in said horizontal wall in an area bounded by the interior surface of said cylindrical filter, k. a one way vent valve in said treatment tank allowing positive pressure in said treatment tank, l. means defining a discharge opening in said horizontal wall from said lower section of said treatment tank, m. a discharge pipe extending from said opening upwardly through said upper chamber of said treatment tank, n. a supply reservoir for a supply of purifying additive, o. a holding tank positioned beneath said reservoir, p. a solenoid actuated valve interconnecting said reservoir and said hoLding tank, q. a conduit interconnecting said holding tank and said lower section of said treatment tank, r. a one way valve in said conduit permitting flow from said holding tank to said treatment tank, and s. control means permitting substantially simultaneous admission of said flushing liquid to said bowl, energization of said macerator pump, and opening of said solenoid actuated valve.
