Retrofit: ZeeWeed 1500, ZeeWeed1500

General Information

TFZW55ZRT is manufactured as the direct retrofit to replace ZeeWeed 1500 UF membrane module in replacement water and wastewater treatment project.

TFZW55ZRT 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
Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU

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
Economical retrofit module for direct replacement of ZeeWeed 1500

Applications

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