I. Introduction
Toray PVDF Hollow Fiber Membrane Module "HFUG series" is a pressurized hollow fiber UF
(Ultra Filtration) membrane module developed with polymer science and membrane fabrication
technologies accumulated over decades of successful membrane manufacturing at Toray
Industries, Inc.
The membrane material is Polyvinylidene fluoride (PVDF). The nominal pore size of the
membrane is 0.01 micrometers.
The module, which is permanently potted in its casing, is pressure-driven which provides filtrate
quality equal to submerged modules, while offering greater TMP range for more flexible plant
operation. Maximum operating pressure is 300 kPa (43.5 psi). The flow direction is outside-in,
which is more suitable for higher turbidity water treatment because of the air-scrubbing
effectiveness. Additionally, outside-in modules can remove suspended solids more effectively
at higher recovery rates compared to inside-out fibers.
1. Characteristics of Toray "HFUG series" Membrane Module
(1) High Filtration Flux
HFUG series provides high filtration flux and stable operation for the filtration of various
raw water sources. The membrane is made with a special spinning method, which enables
high permeability and high fouling resistance.
(2) Excellent Water Quality
HFUG series provides very good water quality for the filtrate, extremely low turbidity since
the membrane has 0.01 micrometers nominal pore size. HFUG series is recommended to
be applied to the tertiary treatment of sewage and RO pretreatment in desalination.
(3) High Mechanical Strength
The membrane of HFUG series has very high mechanical strength because it is made of
PVDF with the special spinning method developed by Toray. HFUG series provides high
integrity and durability under recommended operating conditions.
(4) High Chemical Durability
The membrane material of HFUG series is PVDF, which allows to clean the membrane
with high concentrations of chlorine and with high concentrations of acid resulting in better
cleaning and longer sustainable membrane flux rates
