High Purity Water


High purity water also called deionized water, demineralized water, distilled water and ultrapure water is used for many purposes in the offshore oil and gas industry. In essence this is water that has been highly filtered to remove all suspended solids and then further treated to remove dissolved solids like calcium, magnesium, chlorides, sodium, silica and any other impurities that could cause problems in a process.
