Water purification equipment design pressure vessels shall be licensed units and qualified personnel commitment, subject to national standards People's Republic of China "steel pressure vessel" (GB150-80) and "Pressure Vessel Safety Technology Supervision Regulations" the relevant provisions handle. USP purified water equipment manufacturers China Pharmacopoeia Pharmaceutical Water (2000 edition) were contained in the biological purification of water, because of the use of different ranges and into purified water, water for injection and sterile water for injection, for the first time in the past instead of distilled water purification water, purified water, and the specific definition of purified water is "purified water by distillation, ion exchange, reverse osmosis or other suitable method to obtain water for medicinal" for related enterprises to adopt internationally widely popular RO high water HPW (Highly Purified Water HPW) was prepared and purified water laid the legal foundation. More importantly, the purified water production, the new national pharmacopoeia water for injection is defined as "purified water obtained by distillation of water", so that the RO water for injectable preparation technique into the process is possible. Today, HPW RO-based medicine has been recognized as the representative of the world's major developed advanced technology to become one of the medical preparation of purified water standards. Thousands of net professional manufacturer of water purification equipment water purification equipment 2010 Chinese Pharmacopoeia water, water for injection, pH sterile water for injection, conductivity, total organic carbon (TOC) detection made the following requirements: pharmacopoeia for pH testing new Requirements: pH value should be at 5.0 to 7.0. Pharmaceutical conductivity detection of new requirements: adjusting the temperature of the sample to 25 ℃. Marked installed capacity of 10ml or 10ml or less, the conductivity limit of 25μS / cm; marked installed capacity of 10ml or more when the price of purified water, the conductivity limit for 5μS / cm. Measured conductivity value not greater than the limit value, the penalty for compliance; if the conductivity value is greater than the limit value, the penalty for non-compliance. ③ Pharmacopoeia TOC (TOC) of the new requirements: total organic carbon (TOC) values ??should be at less than 0.5μg / mL. Water purification equipment 1, total organic carbon (TOC) measurement techniques should be able to distinguish between inorganic carbon (carbon dioxide dissolved in water and bicarbonate produced by the decomposition of carbon dioxide) and organic carbon (organic matter is oxidized to produce carbon dioxide), and to exclude inorganic Carbon interference organic carbon determination. 2, shall meet the requirements of the system suitability test. 3, should have sufficient sensitivity to detect biological water purification water purification equipment _ _ thousand net Xinyi purified water provided by the City Environmental Protection Equipment Co., Ltd. thousand net. Dongguan thousand net Environmental Equipment Co. (www.qclean.com.cn) quality services and products, and are subject to approval and confidence in the new and old customers and the industry.
