The Reverse Osmosis Deionized Water System is an advanced water purification solution designed to produce high-purity and ultrapure water for industrial, laboratory, medical, and manufacturing applications. By combining Reverse Osmosis (RO) and Deionization (DI) technologies, the system effectively removes dissolved salts, minerals, organic contaminants, and ionic impurities, delivering water with extremely low conductivity and high resistivity.
System Overview
The Reverse Osmosis Deionized Water Systemsystem operates in two primary stages:
1. Reverse Osmosis (RO) Stage
- Removes up to 95–99% of dissolved solids (TDS)
- Eliminates salts, heavy metals, bacteria, and organic contaminants
- Significantly reduces silica and hardness
- Protects downstream DI resins by lowering ionic load
- RO acts as the primary purification barrier, producing low-TDS water ready for final polishing.
2. Deionization (DI) Stage
- Uses cation and anion exchange resins to remove remaining ionic impurities
- Produces high-resistivity water (up to 18.2 MΩ·cm, depending on configuration)
- Ensures minimal conductivity and ultra-low mineral content
- The DI stage polishes RO-treated water to achieve ultrapure standards.
Key Features of Reverse Osmosis Deionized Water System
- High removal efficiency for dissolved salts and minerals
- Low conductivity / high resistivity output
- Stable and consistent water quality
- Modular and scalable design
- Optional UV sterilization and final filtration
- Real-time monitoring of conductivity and TDS
- Automatic flushing and protection functions
