Purified water system generally refers to a variety of water treatment processes and water quality monitoring system came to achieve the purpose of purified water for a class means. Common impurities include natural water-soluble inorganic, organic, particulate matter, microorganisms and soluble gases. Ultra-pure water is to place these impurities thoroughly as possible. Water purification process currently used methods are distillation, reverse osmosis, ion exchange, filtration, adsorption, ultraviolet oxidation method. Ultra-pure water purification process in general can be roughly divided into four major step pretreatment (primary clarifier), reverse osmosis (produced water), the 2010 version of water purification equipment, ion exchange (can produce 18.2MΩ.cm ultrapure water) and terminal processing (production to meet the special requirements of ultra-pure water). Water purification equipment pretreatment because the water will be pretreated by reverse osmosis purification step again, so we must try to remove the influence of impurities on the reverse osmosis membrane; including large particulate matter, chlorine and calcium and magnesium ions. Thousands of net water purification equipment is a good solution to this problem, design precision filter, activated carbon adsorption filter and softening resin targeted to remove large particulate matter, chlorine and calcium and magnesium ions to achieve the best pretreatment effect . Detection of purified water purified water sampling points chosen correctness purified water sampling must choose a representative sampling point is after providing more accurate data base; at the same time should be allowed before sampling sampling point more than 15 seconds of purified water discharge After the water flow until stable before sampling. This prevents contamination of the sampling points collected by the purified water. The correctness of a purified water sampling methods, anions and cations and particle analysis sample bottle, before the official sampling, pour water out of the bottle again with ultrapure water to clean more than 10 times, gmp water purification equipment, disposable injection 350-400mL ultra pure water, water purification equipment, and to re-clean the water seal bottle. Seal with a clean plastic bag. b, bacteria and TOC analysis sample bottle, in the official sampling, water purification equipment, pour the bottle of water, immediately filled with ultrapure water sampling bottles and caps sterilized seal immediately with clean plastic Seal the bag.
