WATER TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To inhibit corrosion of a thermal apparatus by neither raising a problem with a filter membrane nor using an agent. SOLUTION: The water treatment system is characterized in that an electrodialysis apparatus 4 is installed in a water supplying line 3 to a boiler 2 as the thermal apparatus. The electrodialysis apparatus 4 removes corrosion promoting components of a heat-transfer surface of the boiler 2 which are present as an ion in the feedwater to the boiler 2 and allows corrosion inhibiting components of the heat-transfer surface of the boiler 2 which are present as a non-ion in the feedwater to the boiler 2 to pass.
