Power Plant Reverse Osmosis Systems - 2025 Technical Guide

Why Reliable RO Systems are Critical for Power Generation

✔ Ensures boiler safety - Removes 99.5% silica & dissolved solids
✔ Prevents turbine corrosion - Maintains <10 ppb oxygen levels
✔ Reduces chemical consumption - 40% less acid and antiscalant usage
✔ Meets GB/T 12145 standards - Complies with strict Chinese power industry codes

Industry Fact: Proper water treatment prevents 65% of forced outages in thermal power plants

3 Power Plant RO Configurations

1. Conventional Pretreatment RO (100-500 m³/h)

For: Coal-fired power stations
Recovery Rate: 75-80%
TDS Reduction: >98%

2. Ultrafiltration-RO Integrated (500-2000 m³/h)

For: Combined cycle plants
Feature: Two-stage RO with intermediate softening
Availability: >99%

3. Zero Liquid Discharge Ready (200-1000 m³/h)

For: Water-scarce regions
Advantage: 85-90% recovery with concentrate management

Core Technologies

1. Robust Pretreatment

• Gravity filters: Remove suspended solids to <1 NTU
• Activated carbon: Adsorbs organic matter and chlorine
• Acid/antiscalant dosing: Prevents carbonate scaling

2. High-Efficiency RO Array

• Dow Filmtec LE-440i elements - Low energy, high rejection
• 6:4:2 array design - Optimized flux distribution
• Interstage boosting - Maximizes recovery rate

3. Advanced Monitoring

• Real-time SDI measurement - Predictive membrane cleaning
• Conductivity profiling - Early detection of O-ring leaks
• ORP monitoring - Prevents oxidative membrane damage

Maintenance Protocol
