METHOD AND APPARATUS FOR TREATING WATER

摘要

PROBLEM TO BE SOLVED: To treat water at a low cost by preventing the lowering of the flow of combustion gas or decomposition reaction gas caused by the condensation of moisture in the gas or the generation of rust while performing smooth treatment without shortening the life of a compressor or the like and preventing the lowering of the solubility of Ca in washing water after treatment to suppress the generation of scale and smoothly performing sedimentation treatment before the discharge of treated water to the outside after treatment. SOLUTION: In a method for treating water with CO2 contained in gas selected from combustion gas and decomposition reaction gas, moisture contained in CO2-containing gas is removed prior to treatment.
