We offer deionization system comprising of cationic bed, anionic bed and combination of both known as mixed bed to meet the requirement of high purity water for utility / process applications. This process separately removes cations and anions in different units which involve usage of Weak Acid Cation, Strong Acid Cation, Weak Base Anion & Strong Base Anion units depending on the raw water characteristics, ratio of its contents, quality of treatment desired and capacity of the plant.

Strong Acid Cation / Weak Acid Cation is employed to treat all the cations from raw water e.g. Ca++, Mg++, Na+, K+ etc. This unit comprises of a MSRL / FRP vessel which is internally fitted with inlet distributor and bottom collecting system and externally with frontal pipe work and isolation valve. Unit is charged with cation resin which is regenerated with acid (HCl / H2SO4) after its exhaustion generally designed for once or twice in a day, however, governed by customer / system requirement.

Weak Base Anion ( WBA ) and Strong Base Anion ( SBA ) are almost similar as WAC / SAC units in construction. These units are charged with anion resins and are regenerated with alkali (NaOH).

WBA unit is employed for EMA (equivalent Mineral Acidity) removals whereas SBA takes care for entire anion load i.e. EMA, Silica and Alkalinity. Selection of scheme and mode of regeneration depends on water characteristics, ratio of its content, capacity of the plant and desired treated water quality.

Mixed Bed (MB) unit are used for polishing of treated water from Strong Base Anion Unit or RO plant. MB produced ultrapure water, which is required for high pressure boiler feed water application, semi-conductor and micro-electronics industry applications. In this process Cation and Anion resins are mixed in single vessel and water is passed through resin bed where exchange of ions takes place. For regeneration of MB unit, both resins are first separated from each other by applying upward water-flow due to specific gravity difference, once resin are separated, acid is applied on cation resin and alkali is applied on anion resins respectively to regenerate these resin. MB vessel have specific frontal piping arrangement for the regeneration of resins.
