Water purification equipment design pressure vessels shall be licensed units and qualified personnel to assume purified water USP, People's Republic of China shall be the national standard "steel pressure vessel" (GB150-80) and "Pressure Vessel Safety Technology Supervision" The relevant provisions. USP pharmaceutical water water purification equipment manufacturers of Chinese Pharmacopoeia (2000 edition) as were contained, because of its diverse range of uses and is divided into purified water, water for injection and sterile water for injection, for the first time in the past instead of distilled water and purified water, and specific definition of purified water is "purified water by distillation, ion exchange, reverse osmosis or other suitable methods for medicinal water" for the relevant enterprises to adopt internationally widely popular high-water reverse osmosis HPW ( preparation of purified water and laid a legal basis for Highly Purified Water HPW) method. More importantly, 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.
