Abstract: A treatment unit for use on toilets such as used in small ships including a housing having separate holding chambers with a treatment chamber disposed therebetween. A macerator reduces the size of solids in the first chamber from where the effluent flows into the treatment chamber containing a plurality of chemical tablets for purifying the effluent. The effluent then passes into the second holding chamber from which it is discharged from the unit. Sensing apparatus is provided to inactivate the macerator when the level of tablets is below a preset minimum, and a pressure operated time delay switch is utilized to initiate operation of the macerator upon an increase in pressure in the inlet to the unit.
