HydROtwist 20" X 4.5" Refillable Clear Cartridge with premium Purolite MB4000IND Colour Indicating/Changing Resin.

Suit Big White, Big Blue, Big Clear or Jumbo Stainless Water Filter Housings.

Purolite MB400IND is a high quality resin mixture for direct purification of water. This resin mixture changes color from blue-green to amber on exhaustion. It is designed for use in both regenerable and non-regenerable cartridges. It contains an indicator which shows when the resin is exhausted and can no longer treat the water. The chromatographic profile is sharp when using standard flow rates of 5-40 BV/h, hence a sharp color change is observed and moves progressively down the bed as the resin is exhausted. Passage of water at recommended flow rates through the resin, as supplied, can achieve almost complete reduction of total dissolved solids. The residuals produce average conductivity values of about 0.1 uS/cm for a major portion of the service run. However it will be necessary to cease water production shortly prior to complete color change if highest quality water is essential. Generally water with a conductivity between 5-30 uS/cm is obtained when the green-blue color finally disappears. Exposure of the mixture to the atmosphere for lengthy periods can result in some loss in hydroxide sites of the anion component by conversion to carbonate from carbon dioxide in the atmosphere. This can give rise to loss of treated water quality. Exposure of the resin to daylight can also result in loss of indicator color. Accordingly the resin should be loaded into the cartridges as soon as possible after opening the bags, and any unused resin repacked in airtight packaging which is impervious to daylight.
