Our membranes are calibrated to maintain: Stable permeate conductivity Controlled permeate flow Lower differential pressure growth This balance significantly reduces cleaning frequency and operating cost. 2.

Lower Operating Pressure = Lower Energy Cost Compared to conventional medium-pressure membranes: Reduced pump power consumption Lower mechanical stress Improved long-term stability Over a 3-5 year operating cycle, energy savings substantially reduce total project cost. 3.

Enhanced Anti-Fouling Surface Hydrophilic surface modification improves: Organic fouling resistance Biofouling control Cleanability during CIP When combined with proper pretreatment (SDI ≤ 5), membranes maintain stable output under industrial conditions.

Application Scenarios Our Brackish Water RO Membranes are widely applied in: Groundwater Desalination Municipal and industrial groundwater treatment Municipal Water Treatment Large-scale water treatment plants Boiler Feed Water Preparation for power plants and industrial boilers Textile Industry Process water systems and wastewater treatment Electronics Manufacturing High-purity water for semiconductor production Industrial Wastewater Reuse After proper pretreatment for water recycling If your feed water TDS is below 10,000 ppm , BWRO membranes are typically the most cost-efficient solution.

Frequently Asked Questions Technical guidance for brackish water RO membrane selection and operation Still have technical questions about membrane selection or replacement? Send us your water analysis report -- our engineers will assist you directly. What TDS range is suitable for brackish water RO membranes?

Brackish water RO membranes are typically designed for feed water with TDS between 2,000-10,000 ppm . If salinity exceeds this range, a seawater RO membrane is usually recommended due to higher operating pressure requirements. What is the difference between BWRO and SWRO membranes?

The main differences are: Operating pressure Salt rejection structure Structural strength Energy consumption BWRO membranes operate at lower pressure and are optimized for medium salinity water, while SWRO membranes are designed for high-salinity seawater applications. What is the typical salt rejection rate?

Under standard test conditions (2,000 ppm Na. Cl, 25°C, 15% recovery): 4040 BWRO membrane: ≥ 99% 8040 BWRO membrane: ≥ 99.5% Actual rejection depends on feed water composition and system design. How long does a brackish water RO membrane last?

With proper pretreatment (SDI ≤ 5, turbidity < 1 NTU), typical service life is 3-5 years under industrial operation. Factors affecting lifespan include: Scaling tendency Organic fouling Cleaning frequency Operating pressure Can your membranes replace international brand elements directly? Yes.

Our 4040 and 8040 brackish water RO membranes are dimensionally compatible with standard industrial pressure vessels and can be used as direct replacements in most existing systems without structural modification. We recommend verifying operating pressure and flow design before replacement.

What pretreatment is required before BWRO membranes?

To protect membrane performance, the feed water should meet: SDI ≤ 5 Turbidity < 1 NTU No free chlorine (≤ 0.1 ppm) Proper hardness control to prevent scaling Typical pretreatment includes: Multimedia filtration Activated carbon filtration Softening or antiscalant dosing Cartridge filtration (5 micron) How often should membranes be cleaned (CIP)?

Cleaning is recommended when: Permeate flow declines by 10-15% Salt rejection drops by 10% Pressure differential increases by 15% Actual cleaning frequency depends on feed water quality and system recovery rate. What is the recommended recovery rate for brackish water systems?

Typical system recovery: 60-75% for groundwater applications Lower recovery may be required for high scaling risk water Recovery design should be based on full water analysis and scaling calculation. Do you provide membrane selection support for projects? Yes.
