Reverse Osmosis Membrane

Working Principle

The RE4021-TE operates on the principle of reverse osmosis, leveraging a semi-permeable polyamide composite membrane to remove dissolved solids, bacteria, and organic contaminants. Here’s how it works:

  1. High-Pressure Feed: Pretreated water is pressurized by a pump (up to 600 psig) and forced through the membrane.

  2. Selective Separation: Water molecules permeate through the dense polymer matrix of the membrane, while dissolved ions (Na⁺, Cl⁻, Ca²⁺), organic compounds, and microbes are rejected.

  3. Dual Streams: Purified water (permeate) is collected, while concentrated brine (reject stream) is safely discharged.

The spiral-wound design maximizes surface area and minimizes pressure drop, ensuring efficient filtration even in high-TDS feedwater.


Performance & Advantages

  1. High Salt Rejection: Achieves ≥99.0% NaCl rejection, making it ideal for brackish water and seawater applications.

  2. Low Energy Consumption: Optimized for operation at 115 psi (793 kPa), reducing energy costs by 20% compared to conventional RO membranes.

  3. Anti-Fouling Design: Hydrophilic membrane surface and 34-mil feed spacers minimize particulate fouling and biofouling.

  4. Extended Lifespan: Withstands rigorous cleaning cycles (pH 2.0–11.5) and operates reliably for 3–5 years under proper maintenance.

  5. Broad Compatibility: Suitable for feedwater with TDS up to 5,000 ppm and SDI <5.


Product Structure

The RE4021-TE membrane features a multi-layer composite structure:

  1. Polyamide Active Layer: Ultra-thin, dense polymer film for precise ion rejection.

  2. Polysulfone Support Layer: Provides mechanical strength and porosity.

  3. Fiberglass Outer Shell: Protects against abrasion and chemical corrosion.

  4. 34-mil Feed Spacer: Enhances turbulence to reduce scaling and fouling.

Each element is vacuum-sealed to ensure integrity during transportation and storage.


Application in Wind Power Plants

In wind energy facilities, the RE4021-TE plays a critical role in maintaining operational efficiency:

  • Cooling Water Purification: Removes scaling ions (Ca²⁺, Mg²⁺) from turbine cooling circuits, preventing corrosion and mineral buildup.

  • Lubrication System Maintenance: Supplies ultra-pure water for hydraulic fluids, extending equipment lifespan.

  • Battery Storage Systems: Produces deionized water for electrolyte preparation in energy storage units.

Case Study: A wind farm in coastal China reduced maintenance costs by 40% after installing RE4021-TE membranes, thanks to their consistent removal of silica and iron contaminants.
