High Pure Water EDI Module 8 M3/h 99% Chloride Removal PW WFI Polishing for Pharmaceutical Industry

Product Overview

This DUBHE CEDI module is designed for high pure water production in the pharmaceutical industry, where process water must comply with pharmacopoeia conductivity limits and stay consistently free of dissolved ions, silica and carbon dioxide. Installed downstream of reverse osmosis and electrodeionization pre-treatment, the module provides continuous polishing for purified water (PW) loops, WFI pre-treatment, sterile preparation, ointment and injection manufacturing.

Continuous electric regeneration replaces acid and caustic regeneration of mixed beds, removing chemical storage and regeneration waste from the clean area and supporting validation with stable, repeatable water quality data.

Advantages for Pharmaceutical Plants

• Wide pH range chemical cleaning tolerance, high reliability and long life design.
• CPVC runner plate frame with high weather resistance, built for outdoor and containerised plants.
• Double O-ring sealing with double injection moulding prevents internal and external leakage.
• 2 in 2 out port design, a direct replacement for conventional ordinary runner stacks.
• Specially developed ion exchange membrane with extremely high ion selectivity in a compact volume.
• Designed service life of more than 80,000 hours with 90-95% water recovery.
• Continuous chemical-free operation, simplifying validation and deviation management.
• Over 90% silicon removal and 99% chloride removal for pharmacopoeia compliance support.
• Stable product water quality for PW storage and distribution loop make-up.

Typical Pharmaceutical Applications

• Purified water (PW) generation and loop make-up.
• WFI pre-treatment upstream of distillation or membrane systems.
• Injectable, ophthalmic and sterile preparation water.
• API synthesis, fermentation and buffer preparation.
• Medical device rinsing and cleanroom humidification water.
