Ceramic Membrane Product Water Quality
- Turbidity: <0.1 NTU
- SDI (Silt Density Index): <3
Process Comparison
- Original Process:
Yellow River Water → Reservoir → Chemical Pretreatment → Mechanical Filter → Ultrafiltration → Reverse Osmosis System
- Upgraded Process (with Ceramic Membrane):
Yellow River Water → Reservoir → Ceramic Ultrafiltration System → Reverse Osmosis System
Key Advantages
1. Efficiency: The ceramic ultrafiltration membrane significantly reduces turbidity and SDI, ensuring stable feed water quality for downstream reverse osmosis.
2. Durability: Ceramic membranes withstand high turbidity and fouling, minimizing maintenance costs.
3. Cost Savings: Simplified pretreatment steps reduce operational complexity and energy consumption.
Outcome:
The project successfully met CHEMCHINA’s stringent requirements for boiler demineralized water, ensuring long-term operational reliability and compliance with industrial standards.
