Retrofit: DuPont DOW IntegraPac IP-77XP, IP 77XP, IP77XP

General Information

TFIM-77PXRT is manufactured as a retrofit to replace DuPont DOW IntegraPac IP-77XP (IP77XP) UF membrane module.

TFIM-77PXRT membrane modules are pressurized integrated modules, which are designed and manufactured for the filtration of surface water, potable water, seawater, industrial wastewater and municipal sewage. These UF modules are made of upgraded new generation PVDF hollow fibers with extra permeability.

These UF modules are applied in new systems, as well as directly connected to existing UF systems as replacements, providing high-quality filtrate by removing suspended solids, colloids, pyrogens, bacteria, viruses and other impurities to protect downstream processes.

Features

Outside-to-inside flow direction
Upgraded new generation PVDF hollow fiber
Nominal pore size of 0.03 μm
Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU

Advantages

Integrated design for easy installation
High-quality filtrate
Less energy needed by extra high permeability
Longer service life by high fouling resistance and mechanical strength
Direct and economical module replacement

Applications

Surface water
Potable water
Municipal sewage
Beverage clarification
Industrial wastewater
Reclaimed water reuse
Pre-treatment of sea water desalination
