Kathyon - Pharmaceutical Plant
Water treatment in pharmaceutical plants is a critical step in drug production. Its core objective is to remove various impurities from the water and produce purified water and water for injection that meet stringent pharmacopoeia standards. Raw water (such as tap water) contains ions, organic matter, microorganisms, and endotoxins, which can seriously affect the safety and stability of drugs. Therefore, it must be purified through a series of sophisticated processes.
A typical process includes pretreatment (multi-media filtration, activated carbon adsorption, and chemical treatment), core purification (reverse osmosis, electro-deionization), and final fine treatment and distribution. Among these, reverse osmosis membranes can efficiently remove most dissolved salts and organic matter and are the core unit for producing purified water. Water for injection, which has the highest requirements, requires the complete removal of pyrogens (endotoxins) from purified water through distillation (such as multi-effect distillation) and aseptic delivery under high-temperature circulation to prevent microbial growth. The entire water system must undergo rigorous validation, continuous monitoring, and regular disinfection to ensure that the water quality produced is consistently reliable. This is not only directly related to patient medication safety but also the cornerstone for pharmaceutical companies to obtain GMP certification and guarantee product quality.
