Water treatment systems for pharmaceutical purposes

Water is the key component in pharmaceutical production and in related activities. Different types of water having different standards are used in pharmaceutical production plants. An accurate definition of the uses, of the chemical-physical and microbiological specifications, of sampling and testing programs is needed for the correct design and management of water production and distribution systems. The types of water taken into consideration are purified water and water for injection, being the most critical ones. The water production systems are described analog with the principles of function and the instrumental controls specifying the key features which guarantee the high standards of chemical-physical and biological quality of the water produced. A trouble-free use of water in the plant is related to the holding and distribution system. An overview view of the design criteria and management of such system is considered. Description of the aspects regarding the validation and monitoring of water treatment systems is given.
