The core technological feature of the purified water plant is that it uses the water source that meets the drinking water standard as the raw water, passes through the raw water pressurized pump, and passes through the pretreatment unit composed of multi-media filter, activated carbon filter and softener for primary purification. , and then the water flows through the security filter. Remove particles larger than 5 microns, so that the pretreated effluent can reach the influent conditions of the subsequent system. The pretreated effluent enters the reverse osmosis system for desalination, and after sterilization and disinfection, it reaches the water point. From the perspective of the entire process, the water quality of the medical purified water equipment meets the quality standards stipulated by the state, the water production is stable and reliable, safe and environmentally friendly, and there is no peculiar smell during the water treatment process, and no chemical ingredients are added.
In the purified water plant, the reverse osmosis system is the core water treatment device, which is equipped with flow meters, conductivity meters, pressure gauges, sampling devices and other control elements. When the reverse osmosis system is running, the pretreated effluent is boosted by the high-pressure pump and then enters the primary reverse osmosis device, and then enters the intermediate water tank through the membrane element. This process can retain more than 98% of impurities such as inorganic salts, colloids, and organics. The impervious water is discharged through the concentrate pipe. The first-stage reverse osmosis product water enters the second-stage high-pressure pump and then enters the second-stage reverse osmosis device after being boosted, and enters the reverse osmosis water tank through the membrane element. There is an unqualified discharge valve on the product water side, which can discharge the unqualified product water produced in a short time during startup, shutdown maintenance or commissioning, so as to prevent unqualified product water from entering the subsequent system.
In the production line of the pharmaceutical industry, such as the production of oral liquid, capsules and other products, all equipment and instruments in contact with the product need to be cleaned with purified water to ensure the safety and quality of the product. Therefore, the application of purified water equipment in the pharmaceutical industry is very important.
