Demineralization DM Plant

The demineralization process utilises acid regenerated cation resin & caustic regenerated anion resin to remove minerals from water.

Demineralization on a commercial scale became possible after resin manufacturers developed methods of mass producing a new form of ion exchange resin. When regenerated with caustic (NaOH), this resin removed silica and carbon dioxide from the effluent of a zeolite resin operated in the hydrogen cycle. A standard cation resin of the type commonly found in zeolite softeners, which is regenerated with sulfuric acid as opposed to salt (hence: hydrogen cycle cation), is called a strong acid cation resin. An anion resin with a strong affinity for silica and carbon dioxide is described as a strong base anion resin. An offshoot of the strong base anion resin development was the production of a chemically different resin with a strong affinity for strong-acid anions: sulfate (SO4), chloride (CI), nitrate (NO3), phosphate (PO4), etc. This was called a weak base resin. The weak base resin does not remove silica or carbon dioxide, as does the strong base resin. Therefore, it cannot be used alone to produce the water purity demanded by high-pressure steam plant operations. Less caustic is required to regenerate the weak base resin and it is often coupled with a strong base resin in the same vessel to produce the most economical anion unit operation. The weak base resin is always loaded into the vessel last when the unit is readied for down flow service.

Putting the weak base resin on top of the anion resin bed uses its higher capacity for strong acid removal to insure that the strong base resin can concentrate on removing the weak acids associated with the carbon dioxide and silica (carbon and silicic acids).

The cation and anion vessels of a demineralizer train are piped in series so that the effluent of the cation unit enters the top of the anion unit and the discharge from the anion unit goes to the treated water header or into a polishing unit.

Approx. Price: Rs 35,000 / plant
We provide highly efficient Demineralizatio (DM) Plant for the complete removals of minerals for water viz Salts of Chloride, Sulphate, Nitrate, etc. which are highly detrimental for finish products. Extracting the impurities with  high efficiency, our water  demineralization plant makes the water pure.
Easy to Operate
Our water demineralization plant is fully automatic that provides excellent result. we have curved a niche as one of the supreme DM Plants supplier in India.
The typical process involves the removal of cations (eg.Calcium, Magnesium, Potassium, iron and other heavy metals) by a bed of strong acid cation (SAC) ion exchange resin followed by a second bed of strong base Anion (SBA)
resin of the removal of all anions (Eg. Bicorbonate Alkalinity, Chaloride, sulphate, nitrate, silica and etc.)or a second bed of Weak Base Anions (WBA)resin for the removal of Strong Acid Anions( Eg. Choloride, sulphate and Nitrate)
The Demineralization process is also known as Deionization. It is economical option when feed water TDS is low and low conductivity product water is required.
Our DM pants are available in Manual as well as Automatic configuration
