Deionization method and apparatus

摘要: A deionization method and apparatus comprising separate cation anion removing sections 10a, 10b, the section having tanks 14, 16 24, 26. Respective control valve assemblies 18, 28 fluid communication between various components of respective regeneration cycle exhausted tanks, respectively. Each assembly includes independent water usage monitoring devices 118 which, upon sensing a predetermined quantity discharge by its assembly, effects an associated tank. An tank is regenerated feeding way into in counterflow direction for time. Decationized from on-line then passed through to effect rinse. similarly using passing it direction, followed rinse deionized The also flushing circuit 46 that flushes residual supply line 40a slow prior fast Water step obtained operating chamber 102a restricted passage 218 so back pressure piston maintained order exert force on 78 when necessary.
