DuPont™ IntegraTec™ XP 51IG Ultrafiltration Membrane Module
1. Product Overview
The DuPont™ IntegraTec™ XP 51IG is a high-performance ultrafiltration (UF) membrane module designed for open platform configurations. It combines DuPont’s proven hydrophilic PVDF material with an optimized module design to deliver an efficient, durable, and cost-effective filtration solution for industrial water treatment, municipal wastewater reuse, and reverse osmosis (RO) pretreatment.
2. Key Features & Benefits
Superior Fouling Resistance and Chlorine Tolerance: Featuring XP™ hydrophilic PVDF fibers, the module offers excellent fouling resistance and effective protection against chlorine attack, extending membrane life.
High Filtration Performance: High permeability enables efficient removal of colloidal particles, bacteria, and viruses, ensuring high recovery rates
Open Platform Design: Specifically designed to fit customer-built skids, offering great engineering flexibility.
Compact Design: Short module design ideal for height-limited or containerized installations.
Low Operating Costs: Optimized cleaning protocols reduce chemical consumption, and the module is easy to clean and wet, lowering maintenance costs.
3. Key Applications
Industrial utility water
Industrial wastewater reuse
Municipal wastewater filtration
Reverse osmosis (RO) pretreatment
