Employing ion exchange method and membrane filtration technique, demineralisation is more efficient for creating ultrapure water than other traditional and conventional processes like distillation. The process produces pure water free of chemicals. These minerals are eradicated by the ion resins incorporated in demineralisation process. The process has been efficient and brings the level down to 10mg/l which is desirable for further usage in industries.
Is demineralisation beneficial to your plant?
Certain applications of water in industries need high levels of purity such as feed water, water for high-pressure boilers, rinse water for food and beverage industries, or process streams used in electronics manufacture.
An insight has been provided about the process benefits to various different industries
- 1. Power
Power industry uses water for steam generation. The steam generation water demand requires soft water or in other words, water that has low levels of minerals. If the presence of minerals is beyond the threshold, this will result in corrosion of boilers. Hence the process of demineralisation is of utmost importance to power industries.
- 2. Refinery
In a refinery, the water is fed to high pressure boilers which are quite analogous to the situation we counter in a power plant. The components of various operating machines in refinery can get damaged if the chemical quantity of the incoming water is more. This can create havoc and will result in loss of capital. Demineralisation can eradicate the problem once for all.
- 3. Petrochemical and Chemical
Petrochemical industry uses a lot of water for cleaning purposes and boiler feeds. In petrochemical industry, the process is also used to treat cooling tower blow down. If the water from your blow down needs to be discharged, any discharge your system creates will need to meet all regulatory requirements. In certain areas where water is scarce, there could be large sewer connection fees, and demineralization systems can be a cost-effective solution here because they can help minimize the cost to connect to water and sewer lines.
- 4. Pharmaceuticals
Deionizing has been primarily done for pharmaceutical industry water requirements, in order to assure quality control. Various cosmetic and pharmaceutical products must be free from chemicals and ions.
- 5. Other industries
Mining industries, chemical industries, textile industries and various other industries have water requirements (free of chemicals and ions). This can be only achieved by demineralising the water. Some other industries contain toxic minerals in effluents which can’t be disposed off directly to the sewerage system as per the policies provided by various control boards. It is the only reason the process of demineralisation finds its position in wastewater treatment as well
