What is a Demineralization Water Plant? Demineralization water plant is employed for removal of minerals or dissolved salts from the water. Salts on dissolving dissociate into electrically charged particles called ions: for example common salt will be split into sodium ion (a positively charged ion or cation) and chloride (a negatively charged ion or an anion). If such a solution is brought into contact with a suitable ion exchange material (called resin), some ions from the solution are taken up by the resin and an equivalent number are transferred from the resin to the solution. Ion exchange is thus a reversible interchange of ions between a liquid and a solid.
A simple Demineralization water plant consists of two beds of chemically treated resin beads operating in series. The first column- cation exchanger- converts the dissolved solids in the raw water to the equivalent acids; these acids are removed as the water passes through the second column- anion exchanger. The final product from this process consists essentially of pure water.
When exhausted, the cation exchange resin is regenerated with acid and the anion exchange resin with alkali.In essence the DM plant comprises of resin vessels with charge of strong cation and anion resin; control-panel encompassing a conductivity measurement and alarms, etc; acid and caustic injection facility from bulk, semi-bulk or carboy containers.
What is demineralized water used for?
The high-purity water from a demineralization water plant is typically used as feed water for high pressure boilers in many industries; as wash water in computer chip manufacture and other micro-electronics manufacturing processes, as pharmaceutical process water, and any process where high-purity water is a requirement.
DM water is used as process water in the manufacture of chemicals and fertilizers, food products such as soft drinks, automobiles for rinsing of parts, textiles, etc.
Two-bed OSR DM plants are made in all sizes, from small portable units for laboratories to large multi-stream installations for Thermal power stations, refineries, petrochemical and steel plants.
What is the quality of the treated water from a demineralization water plant?
Electrical conductivity is used to express the purity of demineralized water. Depending on the application pH and/or reactive silica in DM water may also be specified as parameters to measure the purity of DM water.
The quality of the water depends on the type of scheme used:
Cation-Anion-Polishing Mixed Bed
For standard plants our guarantees are as follows:
1) Conductivity 0.1 micromhos /cm-5.0 micromhos/cm. at 25°C (We guarantee conductivity of 0.1 micromhos/cm in very large projects only)
2) Sodium 0.01 mg/l - pH: 7 +/- 0.2
Cation-Anion (Counter-Current Regeneration)
For standard plants our guarantees are as follows:
1) Conductivity 0.5 to 5.0 µS/cm at 25°C- 30 micromhos/cm (We guarantee conductivity less than 10 micromhos/cm in large projects only)
2) Sodium 0.05 to 0.1 mg/l - pH: 7.5 - 9.0
Cation-Anion (Co-Current Regeneration)
With typical co-current regeneration, the outlet quality will depend on the regenerant applied, resin employed and raw water quality
1) Conductivity 5 to 30 µS/cm at 25°C- conductivity can be upto 2 to 5 % of conductivity of raw water
2) Sodium 0.5 to 3 mg/l
How is conductivity measured?
All OSR DM plants are provided with conductivity indicators that have two basic elements: a conductivity cell with electrodes of special design between which demineralized water flows and a sensitive millimeter for measuring the current passing between the electrodes. This current is proportional to conductivity of the water.
