Plate Type Reverse Osmosis Equipment - High Concentration Wastewater Treatment Expert
Introduction: Need a compact and efficient filtration solution? Our flat sheet reverse osmosis membrane equipment features a unique plate-and-frame membrane stack design, offering high membrane area density and excellent fouling resistance. Ideal for high-turbidity feed water, high-viscosity fluids, and special separation applications.
What is Flat Sheet RO Membrane Technology?
Flat sheet RO membrane technology uses a plate-and-frame structure where membrane sheets and flow guide plates are alternately stacked to form enclosed filtration units, representing a high-performance membrane separation technology.
Core Technical Features:
- Robust Structure: Plate-and-frame support structure withstands high pressure and flow impact
- Easy Maintenance: Modular design allows individual inspection, cleaning, or membrane replacement
- Strong Fouling Resistance: Wide flow channels (3-6mm) suitable for high-solid-content liquids
- Application Flexibility: Membrane area and stack number can be flexibly adjusted according to needs
Flat Sheet Membrane vs Spiral Wound Membrane: Technical Comparison
| Feature | Flat Sheet RO Membrane | Traditional Spiral Wound Membrane |
|---|---|---|
| Fouling Resistance | Excellent, wide flow channels (3-6mm) | Standard, narrow flow channels (~0.8mm) |
| Cleaning Effectiveness | Thorough physical cleaning possible, high recovery rate | Mainly chemical cleaning, limited effectiveness |
| Pretreatment Requirements | Lower requirements, handles high turbidity water | Strict requirements need precise pretreatment |
| Maintenance Convenience | On-site disassembly maintenance, low cost | Requires full membrane element replacement |
| Application Fields | Special wastewater, high-concentration materials | Conventional water treatment applications |
Equipment Process Flow
Complete Treatment Process:
- Raw Water Supply: Municipal tap water, surface water, or special wastewater
- Raw Water Tank: Water quantity regulation and buffering
- Booster Pump: Provides initial system power
- Multi-Media Filter: Removes large suspended particles
- Activated Carbon Filter: Adsorbs organics and residual chlorine
- Softening/Dosing Device: Prevents scaling and chemical damage
- Precision Filter: 5μm safety filtration, final barrier
- High-Pressure Pump: Provides required RO pressure
- Flat Sheet RO Membrane Stack: Core separation unit, removes dissolved salts
- Disinfection System: UV or ozone sterilization ensures biological safety
- Product Water Storage: Pure water tank storage meets usage demands
Equipment Shutdown Protection Plan
Short-Term Shutdown Protection (≤15 days):
- Regular Flushing: Low-pressure flushing every 1-3 days
- Temperature Control:
Water temperature >20°C: Flush every 1-2 days
Water temperature <20°C: Flush every 3 days
- Closed Protection: Close all inlet/outlet valves after flushing
- Prevent Deterioration: Avoid bacterial growth in stagnant areas
Long-Term Shutdown Solution:
- Fill with special protective solution (e.g., 1% sodium bisulfite)
- Regularly check protective solution concentration and pH
- Better storage in low temperature, dark environment
