The components of pharmaceutical purified water include a preparation unit and a storage and distribution unit. The preparation unit of pharmaceutical purified water is composed of a pretreatment system and a purified water machine. Its function is to continuously and stably "purify" the raw water so that the effluent quality can meet the internal control indicators of the enterprise or the requirements of the pharmacopoeia. The storage and distribution system consists of a storage unit, a distribution unit and a point-of-use water pipe network unit. Its main function is to transport the purified water for pharmaceutical use to the required process positions under a certain pressure, flow and temperature, and maintain the water quality. Comply with pharmacopoeia requirements.
The essence of producing purified water for pharmaceutical use is to reduce or eliminate potential sources of contamination. The purified water for pharmaceutical use can be used as both raw material and cleaning water, and it is extremely easy to breed microorganisms, so the microbial indicator is one of the most important indicators in the pharmaceutical industry. Based on risk control, effective measures need to be taken to inhibit the growth of microorganisms in the system during the design, installation, verification, operation and maintenance of the pharmaceutical purified water system. In addition, because the purified water for pharmaceutical use is in direct contact with the product, which directly affects the quality of the product, the Pharmacopoeia of various countries regards the purified water system for pharmaceutical use as a key system in pharmaceutical production and implements strict quality control. The standards and uses also put forward clear requirements.
