 ### Purified Water Equipment Introduction 

1. **Reverse Osmosis Related Design**: Both primary and secondary reverse osmosis systems are equipped with return pipelines, and the reverse osmosis equipment includes chemical cleaning and disinfection devices. A pH adjustment device is installed between the primary and secondary reverse osmosis systems to ensure the product water conductivity meets pharmacopoeia requirements. The secondary reverse osmosis membrane uses positively charged anti-fouling reverse osmosis membranes to ensure long-term stable operation of the reverse osmosis equipment. The primary reverse osmosis pipelines are made of 304 stainless steel, while the secondary reverse osmosis uses 316L stainless steel. Online conductivity detection instruments are installed in both primary and secondary reverse osmosis equipment, allowing real-time monitoring of product water conductivity. A low-pressure protection switch is installed before the primary reverse osmosis, and both low-pressure and high-pressure protection switches are installed before the secondary reverse osmosis. The water recovery rates of the primary and secondary reverse osmosis systems are adjustable, with the primary reverse osmosis recovery rate at 60%-65% and the secondary at 70%.

 2. **Pretreatment裝置 and Piping Materials**: The pretreatment裝置 use original imported components, and the piping in the pretreatment equipment room is made of 304/306 sanitary-grade piping materials. 

3. **Purified Water Storage Tank and輸送 Related**: The purified water storage tank is equipped with a breathing filter, and the delivery pipeline includes ultraviolet sterilizers and microporous filters to ensure the pure water meets the輸送 requirements for sanitary pharmaceutical water. - Purified water and pharmaceutical water should be transported using stainless steel pumps that are easy to disassemble, clean, and disinfect. If compressed air or nitrogen is needed to transport purified water and water for injection, the compressed air and nitrogen must undergo purification treatment. - Purified water should be transported using循環(huán) pipelines, with a簡潔 design to avoid dead legs and stagnant areas. The pipelines should be made of stainless steel or other tested non-toxic, corrosion-resistant materials that do not leach contaminating ions. Valves should use sanitary-grade valves without dead corners, and the flow direction should be indicated when transporting purified water. - Pipelines and pumps transporting purified water and water for injection should be regularly cleaned, disinfected, and sterilized, and can only be put into use after passing validation.

 4. **Pressure Vessel Design Requirements**: The design of pressure vessels must be handled by licensed units and qualified personnel, following the national standard "Steel Pressure Vessels" (GB150-80) and the relevant regulations of the "Pressure Vessel Safety Technology Supervision規(guī)程." 

5. **Control System**: The system adopts full automatic control (manual control is also possible), with settings for automatic backwashing and regeneration during operation. ### Purified Water Process Flow Raw Water - Raw Water Pressure Pump - Multi-Media Filter - Activated Carbon Filter - Water Softener - Precision Filter - Primary Reverse Osmosis - pH Adjustment - Intermediate Water Tank - Secondary Reverse Osmosis (with positively charged reverse osmosis membrane surface) - Purified Water Tank - Pure Water Pump - Ultraviolet Sterilizer - Microporous Filter - Point of Use
