D M Plant Resin

Product Description

The  D M Plant Resin comes in handy in taking out mineral content from raw water. In this two column procedure, the water goes through a cation exchanger in the hydrogen form, from where it leaves for the anion exchanger in hydroxyl form.

Generally, demineralisation can be categorised into two types:

Resin - without silica removal

In this stage, the weak base, with the help of strong mineral acids(Hydrochloric acid (Hcl)) is passed through. The degasser situated helps in removing H2CO3, and other major salts. The weak anion base then is regenerated after  exhausting Sodium hydroxide(NaOH) by 1-5%.

Plant Resin -  with silica removal

Under this procedure, water once pushed into an effective acid cation exchanger and is then passed via an equally effective base anion exchanger, which segregates all weak acids such as Carbonic acid (H2C03) and mineral acids such as Sulphuric acid (H2S04).

A degasser in located between the exchangers which removes carbon dioxide. The remaining water has a conductivity less than 30 Micro Mhos. SiO2 lower than 0.5 ppm and pH ranging from 7.5 to 9.5 is attainable

The regeneration of strong  anion exchangers is achievable after exhausting  4 - 5% Sodium hydroxide (NaOH) solution.
