Demineralisation plant offered by us is based on cost effective ion technology with counter current regeneration. DM Plant is the process of removing mineral salts from water by using the ion exchange process. The DM plants are loaded with highly efficient CATION and ANION exchanger and are also loaded with degasification system to remove every trace of minerals from the system. The raw water called influent water is first passed through the CATION resin bed containing SAC Resin in H + form. Ca , Mg & Na are removed and the salts are converted to their respective acids .The corresponding acid containing ANIONS like Cl , SO4 , NO3 are removed by passing the CATION effluent through ANION column containing ANION resin in Hydroxyl Form. The hydrogen ion from CATION neutralizes the hydroxyl ion and produces pure water. The demineralization bed is provided with strong CATIONS and ANIONS to produce 100% pure water.
In Two Bed DM Plant, Strong Acid Cation Exchanger and Strong Base Anion Exchanger resin are used for reducing Total Dissolved Solids up to 2 – 5 ppm. Degasification unit is also provided to decrease the load on ANION Unit. Mixed Bed Units are used in series with Two Bed DM Plant as a polisher unit which can produce treated water having conductivity < 1 mS/cm.
FREEION ENGINEERING Offers Standard DM Plants with FRP / Mild Steel Rubber Lining & SS 316 L (Quartz Lined) construction.
