Retrofit: DuPont DOW SFD-2860, DuPont DOW SFD2860

General Information

TFSF-2860DRT is manufactured as the direct retrofit to replace DuPont DOW SFD-2860 (SFD2860) UF membrane module.

TFSF-2860DRT membrane modules are pressurized modules, which are designed and manufactured for the filtration of surface water, potable water, drinking water, food & beverage water and pre-treatment of sea water desalination etc. These UF modules are made of new generation PVDF hollow fiber membrane with high fouling resistance and hydrophilicity.

TaFlux SF series 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 0.03 μm
Typical filtrate quality SDI≤2.5, turbidity≤0.1 NTU

Advantages

High tolerance for feed water
High-quality filtrate
Less energy needed by high flux
Longer service life by high fouling resistance and mechanical strength
Economical retrofit module for direct replacement of DuPont DOW SFD-2860

Applications

Surface water
Potable water
Drinking water
Beverage clarification
Pre-treatment of sea water desalination
