PRODUCTION OF ULTRA PURE WATER

摘要

PURPOSE:To produce ultra pure water with an extremely little content of the total organic carbon. CONSTITUTION:After pure water with <=10ppm total organic carbon is irradiated by ultraviolet rays with short wavelength, it is passed through a mixed bed of cation exchange resin and anion exchange resin at >=100SV. Therefore, the influence of eluted substances from ion exchange resin is kept to a minimum.
