With its robust design and high efficiency, the XFRLE-400/34i is ideally suited for industrial applications, particularly in wind power plants, where water quality and system reliability are critical.

Technical Parameters
The XFRLE-400/34i is engineered to meet rigorous industrial standards. Key specifications include:

Working Principle
The XFRLE-400/34i operates on the principle of reverse osmosis, a process that leverages semipermeable membranes to separate water from dissolved salts and contaminants. Here’s a breakdown of its operation:

1. Feed Water Inlet: Water enters the membrane module under pressure.

2. Semipermeable Membrane: The polyamide composite membrane allows water molecules to pass through while rejecting ions, organic matter, and colloids.

3. Concentrate Outlet: Concentrated contaminants are flushed out as wastewater.

4. Permeate Outlet: Purified water exits the module for industrial use.

This process ensures high-purity water production with minimal energy consumption, making it ideal for large-scale operations like wind power plants.

Performance and Advantages
The XFRLE-400/34i stands out for its superior performance and reliability:

1. High Salt Rejection: Achieves ≥99.75% NaCl rejection, ensuring water meets stringent purity requirements.

2. Low Energy Consumption: Operates efficiently at lower pressures (≤225 psi for typical applications), reducing operational costs.

3. Anti-Fouling Design: Engineered with a hydrophilic surface to minimize scaling and biofilm formation, extending membrane lifespan.

4. Chemical Resistance: Withstands a wide pH range (2.0–11.5) and aggressive cleaning agents, enabling effective maintenance.

5. Longevity: Robust construction and premium materials ensure consistent performance over 3–5 years with proper care.

Product Structure
The XFRLE-400/34i features a spiral-wound design optimized for high flow and low fouling:

• Membrane Layers: A thin-film composite (TFC) layer of polyamide provides high rejection, supported by a polyester mesh backing.

• Feed Spacer: A 34-mil spacer ensures turbulence, reducing concentration polarization.

• O-Ring Seals: High-quality seals prevent bypass and ensure efficient separation.

• Central Tube: Collects purified water and maintains structural integrity.

This design maximizes water throughput while minimizing maintenance needs.

Application in Wind Power Plants
Wind power plants rely on clean, mineral-free water for turbine cooling, boiler feed, and equipment maintenance. The XFRLE-400/34i addresses these needs effectively:

1. Cooling Water Treatment: Removes dissolved solids and silica to prevent scaling in cooling systems, enhancing heat transfer efficiency.

2. Boiler Feed Water: Ensures water meets the strict purity standards for boilers, reducing corrosion and downtime.

3. Wastewater Reuse: Treats and recycles wastewater from plant operations, aligning with sustainability goals.

4. Remote Operation: Low maintenance requirements and durability make it suitable for off-grid or remote wind farms.

Other Industrial Applications
Beyond wind power, the XFRLE-400/34i excels in diverse sectors:

1. Electronics Manufacturing: Produces ultra-pure water for semiconductor rinsing.

2. Food and Beverage: Ensures microbial-free water for processing and bottling.

3. Pharmaceuticals: Meets USP-grade water standards for drug formulation.

4. Desalination: Converts brackish water into potable water in coastal regions.

5. Chemical Processing: Purifies water for reactor systems and chemical synthesis.

Conclusion
The Reverse Osmosis Membrane Model XFRLE-400/34i represents a leap forward in water treatment technology. With its unmatched salt rejection, energy efficiency, and durability, it empowers industries like wind power to operate sustainably while maintaining peak performance. By investing in the XFRLE-400/34i, businesses can reduce operational costs, minimize environmental impact, and ensure a reliable water supply for critical processes.
