Water and potable water containing salt water and high concentration of salt

摘要

The present invention relates to a method and apparatus for separating salt components contained in seawater by using a reverse osmosis membrane separation apparatus, such as seawater and coastal groundwater, and a water containing a high concentration of salinity, A primary filter in which raw water is sequentially introduced through a raw water storage tank 1 storing raw water of seawater or coastal groundwater and a feed pump 2 to remove clay components, flyton tones, seaweeds, and colloidal materials, The raw water is introduced into the reverse osmosis separator 7 through the high-pressure pump 6 while the fine filter 5 provided with the cartridge 3, the secondary filter 4 and the cartridge of 1 m to 5 m is installed, Some of the permeated water from which the concentrated water has been drained and the salt components have been removed is stored in the washing tub 8 to be used as a chemical mixture for chemical washing and the remainder is transferred to the treated water storage tank 9, Characterized in that the stored permeated water is introduced into the quartz filter (10) supplementing the mineral component through the feed pump (11), or supplied to the boiler feed water or drinking water, and the water and the water containing the high-.
