Industrial Demineralized Water System | RO/EDI/IX Complete Plants
Intro: Need high-purity demineralized water? Our complete DM water plants combine RO, EDI, and ion exchange technologies to remove 99%+ dissolved salts. Custom-engineered solutions for power, electronics, and chemical industries.
What is Demineralized Water?
Demineralized water undergoes advanced treatment to remove dissolved salts and minerals, measured by conductivity (μS/cm) or resistivity (MΩ·cm).
Key Measurements:
- Conductivity: Lower values indicate purer water (0.055 μS/cm)
- Resistivity: Higher values indicate purer water (18.2 MΩ·cm)
- Relationship: Reciprocal relationship between measurements
4 Advanced Demineralization Technologies
1. Reverse Osmosis (RO) Systems
- Technology: Pressure-driven membrane separation
- Efficiency: 98-99% salt rejection
- Benefits: Low energy, high efficiency, chemical-free operation
- Applications: Primary desalination stage
2. Ion Exchange (IX) Systems
