Pharmaceutical water is a raw material in the pharmaceutical production process and participates in the entire production process. Used for ingredients, cleaning, disinfection, washing and other processes. Water treatment equipment, storage tanks, distribution systems, and water use point networks are important components of the system. Water treatment equipment is a standardized product designed and produced to meet the standards of the pharmacopoeia. Practice has shown that the storage and distribution system itself has no purification function. The pollution risk of pharmaceutical water systems is more prevalent in storage and distribution systems. The goal of the system is to ensure that the water quality of production process water meets the standards. The design concept includes continuous water supply, pipeline slope, 3D dead angle control, high or low temperature, smooth and flat surfaces of pipelines in contact with water to prevent microbial growth, frequent cleaning or disinfection, maintaining positive pressure in the circuit, and appropriate design, installation, and maintenance of the system.
