I. Introduction
Toray Submerged UF Hollow Fiber Membrane Rack is the submerged type hollow
fiber UF (ultra filtration) membrane rack developed with the polymer science and
the membrane fabrication technologies accumulated for a long time in Toray
Industries, Inc.
The membrane material is Polyvinylidene fluoride (PVDF). The nominal molecular
weight cut off of the membrane is 150,000 daltons. It has been confirmed that more
than 90% of 150,000 daltons model polymers is consistently removed.
The element, with Polyethylene (PE) protective cylinder, is submerged type. The
maximum operating trans-membrane pressure is 100 kPa (14.5 PSI). The flow
direction is outside to inside which is suitable for high turbidity water treatment
because the air-scrubbing can be adopted to remove suspended solid effectively.
1. Characteristics of Toray Submerged UF Membrane Rack
(1) High Filtration Flux
It 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
It provides very good water quality for the filtrate, extremely low turbidity since
the membrane has 150,000 dalton nominal molecular weight cut off. The rack is
recommended to be applied in high turbidity water treatment, such as for
tertiary treatment of sewage water and industrial waste water reuse.
(3) High Mechanical Strength
The membrane has very high mechanical strength because it is made of PVDF
with the special spinning method developed by Toray. The rack provides high
integrity and durability under recommended operating conditions.
