Deionized water can help reduce operating costs, increase ROI, achieve compliance with an industry standard, reduce down time and more.
Deionized water can be used to process pharmaceuticals, make shampoo, reduce blow down, reduce scaling or comply to a standard. For example, ultrapure water is generally required in pharmaceutical mixing applications, electronics systems and optical manufacturing processes as well as medical, research and dialysis applications.
Comply to a water quality standard such as ASTM or ANSI
Technical standards on water quality have been established by a number of professional organizations, including the American Chemical Society (ACS), ASTM International, the U.S. National Committee for Clinical Laboratory Standards (NCCLS), which is now CLSI, and the U.S. Pharmacopeia (USP). The ASTM, NCCLS and ISO 3696 classify purified water into Grade 1-3 or Types I-IV depending upon the level of purity. These organizations have similar, although not identical, parameters for highly purified water. Many laboratory, pharmaceutical, medical, research and dialysis applications require ultrapure water to meet one of these standards.
DI Water in food and beverage processing quality.
Dissolved ions are also a critical factor in food processing. They can dramatically affect the quality of a product as well as play a role in sanitation. The hardness of water may be altered or treated by using a deionization system. The hardness of water also affects its pH balance, which plays a critical role in food processing. For example, hard water prevents successful production of clear beverages. Water hardness also affects sanitation; with increasing hardness, there is a loss of effectiveness for its use as a sanitizer.
Use deionized water to pretreat boiler feed water to reduce scaling and energy use.
Impurities in water become an important consideration when water is to be used for steam generation. With the trend toward higher-pressure boilers, pretreatment has become the key to successful operation of industrial power plants. Feedwater must be pretreated to remove impurities to control deposition, carryover and corrosion in the boiler system. Also, treated water has no minerals for scale formation and has very low dissolved gases.
Deioniozed water can pretreat cooling tower make-up water to reduce scaling and energy use.
The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating cooling water systems used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants, food processing plants and semi-conductor plants; and for other industrial facilities such as in condensers of distillation columns, for cooling liquid in crystallization, etc. The chemistry of the makeup water including the amount of dissolved minerals can vary and cause problems such as scaling. Treating the circulating cooling water in large industrial cooling tower systems can minimize scaling.
Other commercial and industrial DI water applications.
Deionized water can be used to increase the efficiency of car washes, powder coat paint lines, the purity of manufacturing water and more.
