Desalination and desalination method for seawater and the like using an alkaline ionized water generator and its apparatus

摘要

PPROBLEM TO BE SOLVED: To provide a method and a simply-structured, compact and lightweight apparatus for desalinizing seawater or water containing electrolytes such as sodium chloride, which is easily maintained at a low cost. PSOLUTION: Water containing the electrolytes such as sodium chloride, for example seawater, is supplied to an alkali ionized water generator 6 having a diaphragm 5 and the alkali ionized water produced by electrolysis is again or repeatedly supplied to the alkali ionized water generator 6 to perform electrolysis. Thereby condensed alkali ionized water is discharged from an alkali ionized water exit 11 at a cathode side and desalinized water or fresh water is discharged from a fresh water or desalinized water exit 14 at an anode side.
