REVERSE OSMOSIS DESALINATION APPARATUS AND METHOD WITH PH CONTROL OF SEAWATER

摘要

A reverse osmosis (RO) desalination apparatus with pH control of feed water includes an RO desalination module for receiving a feed water through an inlet pipe to desalinate the received feed water into a product water discharged through a product pipe. Further, the RO desalination apparatus includes a mixer for injecting alkaline material into an end of the RO desalination module to control pH of the feed water. Furthermore, the RO desalination apparatus includes a controller for monitoring properties of a target material to be removed from the product water in real time and controlling flow rates of the feed water supplied to the RO desalination modules and the alkaline material injected by the mixer. Here, concentration of the target material to be removed from the product water is regulated within a preset regulation based on the monitored properties of the target material to be removed.
