Abstract
PURPOSE: To dump waste water into the sea without pollution of the sea surface, by lowering the temperature of the waste water, than that of the sea water before the waste water is dumped into the sea.
CONSTITUTION: When waste water, e.g. waste water during dredging, waste water from a factory, etc., is dumped into the sea, the waste water in a waste water tank 1 is pumped up by a pump 3, carried through a line pipe 2 into a cooler 4, where the waste water is cooled to a predetermined temperature, i.e. a temperature lower than that of the sea water into which the waste water is drained, and then drained through a drain pipe 5 into the sea water. Because of this treatment, the cooled waste water, which has a larger density than that of the circumferential sea water, does not disperse into the sea water freely, but sinks until its density becomes equal to that of the sea water. Consequently, the sea surface is not polluted.
