Medical pure water equipment is specifically designed for water treatment in the medical field, providing high-quality, high-purity water to meet the water demands of medical laboratories, hospitals, pharmaceuticals, and other sectors. Below are some detailed information about medical pure water equipment:

1. Working Principles:
- Reverse Osmosis Technology: This is one of the core technologies of medical pure water equipment. Utilizing the principle of semi-permeable membranes, water is forced through the membrane under pressure while impurities are retained, thereby removing most salts, organic matter, microorganisms, and other contaminants to achieve initial purification.
- Ion Exchange Technology: Through exchange reactions between ion exchange resins and ions in the water, specific ions are removed, further enhancing water purity. For example, calcium and magnesium ions are eliminated to reduce water hardness.
- Electrodeionization (EDI) Technology: Under the influence of an electric field, ion exchange membranes selectively migrate ions in the water, achieving deep purification. EDI technology continuously removes ions without the need for chemical regeneration, offering advantages such as high efficiency and environmental friendliness.
- Ultraviolet Sterilization: Ultraviolet light disrupts the DNA structure of microorganisms, achieving sterilization and disinfection to ensure that the microbial indicators of the output water meet requirements.
2. Process Flow:
- Traditional Process Flow: Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → Primary reverse osmosis unit → Intermediate water tank → Intermediate water pump → Ion exchanger → Purified water tank → Pure water pump → Ultraviolet sterilizer → Microporous filter → Point of use.
- Two-Stage Reverse Osmosis Process Flow: Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → First-stage reverse osmosis → pH adjustment → Intermediate water tank → Second-stage reverse osmosis (positively charged reverse osmosis membrane surface) → Purified water tank → Pure water pump → Ultraviolet sterilizer → Microporous filter → Point of use.
- New Process (Compliant with International Pharmacopoeia Recommendations): Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → First-stage reverse osmosis → pH adjustment → Intermediate water tank → Second-stage reverse osmosis (positively charged reverse osmosis membrane surface) → RO water tank → RO water pump → TOC decomposer → EDI system → Purified water tank → Pure water pump → Ultraviolet sterilizer → Microporous filter → Pasteurization → Point of use.
