Abstract
A sewerless recirculating toilet and human waste storage system wherein human waste products and a flushing fluid of a specific gravity less than water are received from a commode, the waste products are separated from the flushing fluid, the separated waste products are stored indefinitely without additional treatment in a state of suspended animation for possible subsequent by-products recovery therefrom and the separated flushing fluid is stored on top of the separated waste products until a portion thereof is recycled back into the commode in a purified state for flushing the commode.
Claims21
In a method for recirculating a non-aqueous flushing fluid into a commode having a predetermined quantity of said flushing fluid associated therewith wherein said commode is in fluid communication with a human waste products and flushing fluid outlet, the improvement which comprises the steps of:
- placing a tank in fluid communication with said outlet for receiving said mixture of human waste products and flushing fluid therein;
- retaining said mixture in said tank until said flushing fluid separates from said human waste products and floats as a layer on the top in sealing contact with said human waste products;
- storing said layer of flushing fluid in said tank until said flushing fluid is recycled back into said commode by maintaining said layer of flushing fluid in sealing contact across the upper surface of said human waste products in said tank until said flushing fluid cuts off substantially all oxygen from said human waste products thereby stopping aerobic bacterial action in said human waste products;
- and
- continuing to maintain said layer of flushing fluid in sealing contact with said human waste products until the pH of said human waste products reaches a level at which anaerobic bacterial action in said human waste products virtually ceases.
In a sewerless recirculating toilet and human waste products storage system, having a commode with a flushing fluid of a specific gravity less than water associated therewith, a trap controlled waste products and flushing fluid outlet leading from said commode to a waste products and flushing fluid separation space, a storage space for the separated human waste products, the improvement which comprises:
- fluid and human waste storage means operatively connected to said outlet for receiving said mixture of human waste products and said flushing fluid, separating said flushing fluid from said human waste products, storing said human waste products for an indefinite period of time in a state of suspended animation by maintaining said layer of flushing fluid in sealing contact with said human waste products until said flushing fluid cuts off substantially all oxygen from said human waste products thereby stopping aerobic bacterial action in said human waste products, and continuing to maintain said layer of flushing fluid in sealing contact with said human waste products until the pH of said human waste products reaches a level at which anaerobic bacterial action in said human waste products virtually ceases, so that said flushing fluid is stored on top of said human waste products and a portion of said stored flushing fluid may be recycled back into said commode, when desired.
