Introduction

LEFILTER, a leading Chinese manufacturer specializing in fluid purification solutions, introduces the Reverse Osmosis Membrane Model CPA3-LD-8040. Engineered for high-efficiency desalination and water purification, this membrane is ideally suited for pharmaceutical, food & beverage, and industrial applications requiring ultra-pure water. As a direct replacement for premium brands like Dow Filmtec and Hydranautics, the CPA3-LD-8040 delivers superior performance, durability, and compliance with international standards such as USP and EP.

Technical Parameters

The CPA3-LD-8040 is a high-performance spiral-wound reverse osmosis (RO) membrane designed for challenging water sources. Key specifications include:

Working Principle

The CPA3-LD-8040 operates based on the reverse osmosis principle:

1. Pre-Filtration:
   

• Feed water passes through a 5-μm security filters to remove particulates.

2. Reverse Osmosis:
   

• High-pressure pumps force water through the semipermeable polyamide membrane, which rejects dissolved solids (e.g., salts, organics) and allows pure water to pass.

3. Separation:
   

• Concentrated contaminants  are discharged, while purified water  is collected for downstream use.

Key Features & Advantages

1. High Salt Rejection:
   

• 99.8% NaCl rejection ensures ultra-pure water for critical applications.

2. Low Energy Consumption:
   

• Operates at 200 psi (1.379 MPa), reducing energy costs by up to 30% compared to traditional membranes.

3. Anti-pollution design:
   

• Hydrophilic surface and optimized flow channels minimize fouling, extending service life and reducing cleaning frequency.

4. Wide Compatibility:
   

• Fits standard 8” pressure vessels and integrates seamlessly with existing RO systems.

5. Chemical Resistance:
   

• Resists chlorine (up to 1,000 ppm·hrs), acids, and alkalis, ensuring durability in harsh environments.

Application in Pharmaceutical Water Treatment

The CPA3-LD-8040 is critical for pharmaceutical applications:

1. Purified Water (PW) and Water for Injection (WFI):
   

• Removes endotoxins, bacteria, and viruses to meet USP, EP, and JP standards.

2. Process Water:
   

• Ensures high-quality water for formulation, cleaning, and equipment rinsing.

3. Wastewater Recycling:
   

• Recovers solvents and reduces wastewater discharge, supporting sustainability goals.

Other Industrial Applications

1. Food & Beverage Industry:
   

• Clarifies juices, wines, and dairy products; removes pathogens for shelf-life extension.

2. Power Generation:
   

• Treats boiler feedwater to prevent scaling and corrosion.

3. Electronics Manufacturing:
   

• Produces ultra-pure water for semiconductor fabrication.

4. Oil & Gas:
   

• Desalinates produced water for reuse in hydraulic fracturing.
