ABSTRACT:
An automatic dual-mode shipboard wastewater treatment system employing ozone for disinfection of the primary effluent. Solids are removed and pumped, for example, to the ship's boiler or other equipment for incineration, while the liquid waste is pumped through a series of ozone reactors and then to a holding tank from which it is discharged overboard, after accumulating to a predetermined level. The system operates continuously by recirculating the effluent, during low flow periods, between a second holding tank and the ozone reactors.
