WATER-TREATMENT METHOD AND APPARATUS

摘要

In a water-treatment system provided with an ozone generator, an ozone-treatment device, a filtration device and a reverse osmotic membrane, a device having a baffle plate at a definite position therein is employed as the ozone-treatment device. Seawater is flown into this ozone-treatment device to give a turbulent flow so that ozone diffuses throughout the seawater, thereby performing the ozone-treatment. After thus forming oxygen nanobubbles containing concentrated mineral ions around the flow, the seawater is passed through the filtration device and the reverse osmosis device. Then, the desalinated water is flown out from the water-treatment system. According to this method, fresh water containing a large amount of dissolved oxygen and being rich in minerals can be obtained from seawater.
