In mixed-bed deionizers the cation-exchange and anion-exchange resins are intimately mixed and contained in a single pressure vessel. The thorough mixture of cation-exchangers and anion-exchangers in a single column makes a mixed-bed deionizer equivalent to a lengthy series of two-bed plants. As a result, the water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed plant.
Although more efficient in purifying the incoming feed water, mixed-bed plants are more sensitive to impurities in the water supply and involve a more complicated regeneration process. Mixed-bed deionizers are normally used to ‘polish’ the water to higher levels of purity after it has been initially treated by either a two-bed deionizer or a reverse osmosis unit.
It consists of an in-built pre filter and very high exchanging capacity non-corrosive CATION and ANION resin columns pre-fitted with imported RESINS for efficient results having treated water parameters conforming to IS- 1069/64. It yields chemically pure water equal to multiple distilled water having a conductivity of less than 10 micro Siemens / cm and pH of 7.5 to 9pH. Fitted with sturdy PVC multi-control valve and connected direct to water taps. The conductivity meter operates on both AC supply and 9.0 V DC battery. Supplied with one plastic chemical proof regeneration tank and the complete unit in housed in a painted M.S. trolley for easy mobility. Available with analogue as well as Digital conductivity meter.
