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:
ISO 9001, ISO 14001, NSF/ANSI 61, FDA (food contact)
Working Principle
The CPA3-LD-8040 operates based on the reverse osmosis principle:
Pre-Filtration:
Feed water passes through a 5-μm security filters to remove particulates.
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.
Separation:
Concentrated contaminants are discharged, while purified water is collected for downstream use.
Key Features & Advantages
High Salt Rejection:
99.8% NaCl rejection ensures ultra-pure water for critical applications.
Low Energy Consumption:
Operates at 200 psi (1.379 MPa), reducing energy costs by up to 30% compared to traditional membranes.
Anti-pollution design:
Hydrophilic surface and optimized flow channels minimize fouling, extending service life and reducing cleaning frequency.
Wide Compatibility:
Fits standard 8” pressure vessels and integrates seamlessly with existing RO systems.
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:
Purified Water (PW) and Water for Injection (WFI):
Removes endotoxins, bacteria, and viruses to meet USP, EP, and JP standards.
Process Water:
Ensures high-quality water for formulation, cleaning, and equipment rinsing.
Wastewater Recycling:
Recovers solvents and reduces wastewater discharge, supporting sustainability goals.
Other Industrial Applications
Food & Beverage Industry:
Clarifies juices, wines, and dairy products; removes pathogens for shelf-life extension.
Power Generation:
Treats boiler feedwater to prevent scaling and corrosion.
Electronics Manufacturing:
Produces ultra-pure water for semiconductor fabrication.
Oil & Gas:
Desalinates produced water for reuse in hydraulic fracturing.
