Here are just a few areas where we can be of service including High-purity, Deionized, De-mineralized, Lab-grade, and Medical-grade water.
“Ultrapure” is the water treatment industry term applied to water which meets stringent limits on several or all of the following: dissolved and suspended solids, organic carbon, dissolved gases and biological organisms (e.g., bacteria, viruses, pyrogens). Water meeting these characteristics is generally required in pharmaceutical, electronics and optical manufacturing processes as well as medical, research and dialysis applications. Several standards-setting organizations publish standards governing ultrapure water purity. Examples include USP, ASTM, CAP, NCCLS, ANSI and AAMI.
According to Wikipedia.org
Deionized water, also known as demineralized water (DI water, DIW or de-ionized water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.
Ion exchange demineralization of water is frequently accomplished by in-plant deionizers which automatically regenerate on a pre-set frequency, consuming acid and caustic and discharging a waste stream containing high concentrations of the acid and caustic. These systems are expensive to purchase and are very maintenance-intensive.
Deionized Water Tank Exchange Service, is also called “Portable Exchange Deionization” or “Service Deionization”. This process flows your process water through tanks at your facility containing deionization resin which we exchange for fresh tanks when needed. After exchanging, your tanks are regenerated at a Culligan Service Center for reuse in the future. This way you have minimal up-front investment by eliminating complicated plumbing and installation and you’re only paying for the high-purity water that you need.
Advantages of Deionized Water Tank Exchange Service include:
- No chemicals or hazardous waste; Unlike Reverse Osmosis and other technologies that have waste water or use chemicals to improve water quality, Deionized Water Tank Exchange produces no waste and requires no chemicals. Which means you won’t need hazardous chemical training from OSHA.
- No maintenance costs. With your own water treatment, you have to maintain it. With DI Exchange, Culligan exchanges exhausted tanks as required.
- No capex or up-front investment. You pay per exchange or per thousand gallons of DI water you use.
- Flexibility to meet varying flow requirements and water quality. Flows from 0.5 gpm to 500 gpm and quality from 50,000 ohm-cm to 18,000,000 ohm-cm.
