摘要： PURPOSE: A system and a method for using carbon dioxide separated from the seawater in the recalcification of treated water are provided to separate carbon dioxide gas from seawater in a desalinating process through a gas transferring membrane. CONSTITUTION: A reverse osmosis filter(22) is prepared. A gas transferring membrane with first and second reverse flow channels(34, 36) is prepared. Seawater is supplied to a first reverse flow channel, and reverse osmosis penetrant is supplied to the second reverse flow channel. Sulfuric acid is applied to the upstream end part of the first reverse flow channel. Sulfuric acid is reacted with calcium bicarbonate in the seawater to generate carbon dioxide. The carbon dioxide passes through the gas transferring membrane to separate from the first reverse flow channel. Calcium hydroxide is applied to the downstream end part(48) of the second reverse flow channel. Separated carbon dioxide is reacted with calcium hydroxide to generate calcium bicarbonate. The calcium bicarbonate is added to the reverse osmosis penetrant to apply hardness and alkaline characteristic to water.
摘要翻译：目的：提供一种使用从海水中分离出来的二氧化碳在再水化处理水中的系统和方法，用于通过气体转移膜将脱盐过程中的二氧化碳气体从海水中分离出来。构成：制备反渗透过滤器（22）。制备具有第一和第二反向流动通道（34,36）的气体转移膜。将海水供应到第一反向流动通道，并且向第二反向流动通道提供反渗透渗透剂。硫酸被施加到第一反向流动通道的上游端部分。硫酸与碳酸氢盐在海水中反应生成二氧化碳。二氧化碳通过气体转移膜以与第一反向流动通道分离。将氢氧化钙施加到第二反向流动通道的下游端部（48）。分离的二氧化碳与氢氧化钙反应产生碳酸氢钙。将碳酸氢钙加入到反渗透渗透剂中以对水施加硬度和碱性特征。
