Demineralization Plant-DM Plant

Demineralization is the process of removing mineral salts from water by using the ion exchange process. With most natural water sources it is possible to use Demineralization and produce water of a higher quality than conventional distillation.

Demineralization or Deionization of water consists in the removal from it of all water dissolved substances e.g of all Cations and Anions. The raw water is first treated in Hydrogen cation exchange column in which the mass of cations and others are removed (retained) and replaced by the cation hydrogen. After this, water mainly contains anions and it is directed to Anion column in which the column is built up of anion exchange material that retains all anions of strong acids and permits the passage of anion for complete demineralization
The conductivity meter provided on the panel is for testing the out-coming treated water from the ANION column. The reading of 10 or less micromhos in the conductivity meter shows that the out- coming water is of good quality. If it is above, the DM plant (cation & anion columns) has to be regenerate with Hydrochloric acid and Sodium Hydroxide

THE PLANT CONSISTS OF:
A set of PVC columns, charged with high exchange capacity cation & anion resin with strainer arrangement.

Digital conductivity meter to monitor the quality of deionized water.
A set of flexible PVC tubes with connectors for inlet, outlet and inter-connection
All are housed in a trolley mounted, corrosion proof mild steel stand for easy mobility,
PVC / FRP regeneration tank for regeneration.
