Why Choose Low Pressure RO Membranes?
Lower Operating Pressure = Lower Energy Consumption Compared with conventional brackish water membranes: Reduced pump power demand Lower electricity cost per m³ Decreased system mechanical wear Over long-term operation, energy savings significantly reduce total cost of ownership (TCO).
Stable Salt Rejection Performance Despite lower operating pressure, our membranes maintain: ≥ 99% salt rejection Stable permeate conductivity Controlled permeate flow Balanced flux design prevents excessive fouling risk.
Improved System Stability Lower pressure operation results in: Reduced membrane compaction Lower pressure drop growth Longer membrane lifespan Ideal for systems operating 24/7 in municipal and industrial environments.
Application Scenarios Low Pressure RO Membranes are suitable for: Municipal tap water purification Surface water desalination Industrial process water Cooling tower makeup water Boiler feed water systems Pre-EDI applications If feed water TDS is below 5,000 ppm and energy optimization is a priority, low pressure membranes are typically the most cost-effective option.

Technical Support Frequently Asked Questions Expert answers to common technical questions about our low pressure RO membrane systems What is the difference between low pressure and standard brackish water RO membranes?
Low pressure RO membranes achieve similar salt rejection but operate at lower applied pressure, resulting in reduced energy consumption and lower pump load. What TDS range is suitable for low pressure RO membranes? Typically 500-5,000 ppm.
For higher salinity water, standard brackish or seawater membranes may be required. Will lower pressure reduce salt rejection? No. When operated within recommended parameters, low pressure membranes maintain ≥99% salt rejection under standard conditions. Can low pressure membranes reduce electricity cost significantly?
Yes. Lower operating pressure reduces pump power demand, which lowers energy cost per cubic meter, especially in continuous industrial systems. Are these membranes compatible with existing 4040 and 8040 systems? Yes.
They are dimensionally compatible with standard industrial pressure vessels and can typically replace conventional brackish membranes directly. What pretreatment is required? Feed water should meet: SDI ≤ 5, Turbidity < 1 NTU, No free chlorine, Proper hardness control.
Typical pretreatment includes multimedia filtration, carbon filtration, softening, and 5-micron cartridge filtration. What is the expected service life? With proper operation and pretreatment, membrane lifespan is typically 3-5 years in industrial applications. Do you provide OEM or private label services? Yes.
We offer OEM branding, custom packaging, bulk supply, and long-term cooperation for distributors and EPC contractors. Still have questions about our membrane solutions? .
