Membrane-Based WFI System
♦ Main Application:
Membrane-based WFI system using advanced RO, EDI and ultrafiltration technologies to produce high-purity Water for Injection compliant with GMP and pharmacopoeia standards.
Membrane-Based WFI System
A Membrane-Based WFI System is an advanced water treatment solution designed to produce Water for Injection using membrane technologies instead of traditional thermal distillation.
By combining RO, EDI, UF, and advanced sanitization technologies, the system generates high-purity WFI while reducing energy consumption and operating costs.
What Is a Membrane-Based WFI System?
A Membrane-Based WFI System is a non-distillation WFI generation technology that uses multiple membrane barriers and purification stages to achieve Water for Injection quality.
The combination of RO, EDI, UV oxidation, and UF removes dissolved salts, organic contaminants, bacteria, endotoxins, pyrogens, and particulates.
