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 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
