The Importance Of Deionized Water in Bulk In Different Manufacturing Processes
Water deionization is a treatment process involving removal of minerals in water and so it is also called demineralization. It is achieved by passing feed water through ion exchange resins. The result is ultra pure water, but water quality largely depends on the process and the equipment used. Nonetheless, demineralized water is an important constituent of many industrial processes.
Cosmetics and pharmaceutical companies purchase pure water in bulk quantities. Some companies actually have their own water treatment facility but this is going to add much to the cost of operations. DI water is used to make cosmetic products and medicines because it does not affect the chemical nature of substances. Plain water contains minute quantities of substances, such as chlorine, sulphates, and various metal ions.
In industrial and manufacturing plants, deionized water in bulk is also used in various key processes. This pure water is important primarily as a cleaning agent. Many aqueous cleaners are made of surfactants and a large percentage of pure water. Some cleaning agents just contain DI water. Pure water is used in cleaning windows, glassware, equipment, instruments, utensils, and even large storage tanks primarily because it does not cause scaling. Spot-free cleaning can only be achieved with the use of water devoid of ions because plain water can leave mineral deposits on surfaces that make cleaning inefficient. Usually, DI water is important during the rinsing process, when high pressure jets of water are employed for thorough rinsing.
Maintaining deionizing equipment can be expensive for companies because the resin beds require regular regeneration as part of maintenance process. This is because the resins collect impurity from feed water. Bacteria may also collect and thrive in resins and cause spoiling. Thus, their sterilization is another important aspect.
The manner of deionization is even more important in pharmaceutical industry because it demands water that is not only devoid of ions but also devoid of organics. For industrial applications, DI water testing is carried out only through conductivity and resistivity tests, which indicate the presence of salts but not the presence of non-ionic substances and impurities.
Affiliating with water companies is often important for many companies. Transportation and shipment of pure water generally do not involve chemical safety precautions. Manufacturers use PVC plastics as containers. According to some experts the material containers are made of must be checked for compatibility with demineralized water because it can corrode some materials. But this inherent corrosiveness is not backed up by evidence but remains a speculation.
Deionized water is also used in automotive industry. Car wash shops use this type of water during the last rinsing because it does effectively remove foam, cleaning solution, and dirt from car windows and surfaces. Car lead-acid batteries also need deionized or distilled water after charging when their water level drops below normal.
