Abstract: A process of dissolving into to-be-treated water a peroxodisulfate and metal ions other than ions of alkali metals is performed by pouring equipment. An ultraviolet irradiation apparatus performs a process of treating the to-be-treated water, having the peroxodisulfate and the metal ions other than ions of alkali metals dissolved therein, with ultraviolet rays. By performing UV treatment on the to-be-treated water having the peroxodisulfate and metal ions dissolved therein, the inventive method and system achieve improved TOC decomposing performance and thus can particularly decompose a urea component in an efficient manner. Further, the to-be-treated water may be treated with an ion-exchange resin at a subsequent stage in such a manner that organic acids contained in the to-be-treated water having been subjected to the UV treatment are adsorbed to the ion exchange-resin, with the advantageous result that the concentration of TOC present in the to-be-treated water can be reduced.

Abstract: A water treatment system comprises a flow path through a first activated carbon filter, a second activated carbon filter downstream of the first activated carbon filter, a particulate filter downstream of the second activated carbon filter, for example a ceramic membrane, and a UV sterilizer downstream of the particulate filter. Ozone is introduced into the process water ahead of a water storage vessel for storing treated water produced by the system. A recycle subsystem is periodically operated to withdraw treated water from the water storage vessel to form recycled water, introduce the recycled water to the water lines upstream of the UV sterilizer, and return the recycled water to the water storage vessel. A main programmable logic controller (PLC) controls a flow of the process water through the water treatment system and controls the recycle subsystem.

Abstract: A desalination system includes a vertical column with a lower end submerged into a body of liquid to be treated. The column has a dark-colored outer surface able to absorb electromagnetic energy, and at least one vacuum compressor is connected to provide a vacuum pressure in the vertical column such that the liquid is drawn into the vertical column through openings in the vertical column. A condensing dome has a main shell and that receives vapor of the liquid in the vertical column via a vapor port joining the vertical column and the condensing dome. A wind-driven outer turbine surrounds the main shell of the condensing dome and draws outside air into a space around the main shell of the condensing dome. A tank is connected to the condensing dome via a pipe and receives desalinated liquid from the condensing dome.
