Demineralized water is water that has been purified to remove all or most of its salt ions and minerals such as Calcium, Chloride, Sulphate, Magnesium, and Sodium. Demineralized water has applications across industries including Textiles, Pharmaceuticals, Breweries, Swimming pools, Hospitals, Automobile, etc. It is also known as DM or Demin water. Demineralized Water is used for scientific methods like cosmetic manufacturing.
User friendly, low maintenance and easy to install.
Simpler distribution and collection systems.
Pre dispatch assembly check.
Single valve operation is compared to the six valves in conventional filters.
Less Power Consumption
High shelf life
Boilers feed Water
Automobile and Battery
In the context of Water purification, ion-exchange is a rapid and reversible process because impurity ions present in the water are replaced by ions released by an ion-exchange resin. The impurity ions are taken up by the resin, which must be regenerated in a certain period to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Metals are Positively-charged and positively charged ions are called cations whereas non-metals are usually negatively-charged and negatively charged ions are called anions. When minerals, which are salts of base and acid are mixed in water, they get ionized into Anions and Cations. Demineralising of water is a process of removing these anions and cations. DM water is not fit for drinking, this water is used in applications where water with low salt content or low conductivity is required. It is the most economical means of water purification and is used where the least conductivity is required. Generally, these ions are widely found in raw Water :
Chloride ( Cl-)
Demineralised water is usually made either by ion exchange electrode ionization or membrane filtration. Membrane filtration can be more efficient of creating ultrapure water.
Demineralised water is used in:-
Laboratory applications- demineralised water is used as a cleaning agent and mostly as solvent in laboratories. It is used to prepare buffer solutions and to dilute chemical concentrations. It is used to clean the equipments and containers in the chemical laboratories.
Demineralised water is used in automotive industry- It is widely used in lead-acid batteries, gas turbine engines and cooling systems of cars and aircrafts specifically high speed super-sonic cars.
Demineralised water is used in pharmaceutical manufacturing.
Owing to its versatility, De-mineralised water is used in many areas beyond the aforestated uses. DM water is used in petrochemical usages; high pressure boiler feeds; steam applications like steam irons and steam raising; laser cutting and laser cooling; fire extinguishers; etc.
In the power industry, for steam generation and for boiler feed water demineralized water is used. For steam generation to power turbines high-pressure boilers are required for which the maximum removal of impurities is a requisite.
The boiler feed water resultant of condensation of steam inside the boiler where water particles are collected and condense. The condensate contains dissolved gases such as oxygen and carbon dioxide owing to those severe corrosion can be caused on boiler pipes and parts. These gases are removed with demineralisation.
Demineralised water is used in refineries of the sort of power industry, to feed their high-pressure boilers. As high-pressure boilers require higher quality of water sans less contaminants, demineralisation is the solution either by ion exchange or reverse osmosis or nanofiltration or membrane filtration.
Demineralisation is also used for the petrochemical and chemical industries which require high purity boiler feed water. Further for treating cooling tower blowdown demineralisation is used.
For sanitising containers and equipments the mineralised water is used in the food and beverage industry as food and beverage production require ultrapure water due to quality regulations.
The versatility of the demineralised water shows that it can be used in many areas.
