Waste treatment system
Abstract
Abstract A self-contained waste treatment system includes a bowl for receiving liquid and solid wastes and a macerator associated with the bowl for macerating the solid wastes and pumping the resulting mixture of liquids and divided solids to a receiving tank. An upstanding, tubular filter is mounted in the receiving tank and surrounds an opening in a bottom wall of the tank. Within the tubular filter a tubular magazine is positioned having a closed upper end, an open lower end and a series of openings through a lower section of its side wall. The magazine is also provided with a nipple at its lower end which is received in an outlet from the receiving tank and a filter pad is received in the magazine and lies across its open lower end. A stack of chemical additive tablets, such as calcium hypochlorite, are received in the magazine with the lower most tablet resting upon the filter pad. With this construction the mixture of liquid and solid wastes pumped to the receiving tank are separated by the tubular filter with the solids being retained in the receiving tank and the liquids passing through the filter to the tubular magazine. As the liquids enter the magazine through the opening in the lower end thereof pressure in the magazine builds up, preventing the magazine from being flooded. The chemical additive tablets in the magazine therefore, are dissolved sequentially from the bottom of the stack as the liquid passes through the filter and out the discharge opening in the receiving tank.
