Retrofit: ZW1500

General Information

TFZW55RT is manufactured as the direct retrofit to replace ZW 1500 UF membrane module in water and wastewater treatment retrofit replacement project.

TFZW55RT ultrafiltration (UF) membrane module is a pressurized module, which is designed and manufactured for the filtration of surface water, potable water, seawater, industrial waste water and municipal sewage. These UF modules are made of new generation PVDF hollow fiber membrane with high fouling resistance and hydrophilicity.

TFZW55RT 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
New generation PVDF hollow fiber
Nominal pore size of 0.02 μm

Advantages

High tolerance for feed water
High-quality filtrate
Less energy needed with high flux
Longer service life by high fouling resistance and mechanical strength
Direct and economical module retrofit

Applications

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