UF system for drinking water flow chart:
Ultrafiltration membranes are used extensively in water treatment
projects. Ultrafiltration technology plays an increasingly
important role in the fields of reverse osmosis pretreatment,
drinking water treatment, and reuse of water. Ultrafiltration
technology plays a key role in the sterilization and turbid removal
of alcohol and beverages, the depyrogenation of pharmaceuticals,
and the concentration of foods and pharmaceuticals.
The range of ultrafiltration filtration pore size and molecular
weight cut-off has been ambiguously defined. It is generally
considered that the ultrafiltration membrane has a filtration pore
size of 0.001 to 0.1 μm and a molecular weight cut-off (MWCO) of
1,000 to 1,000,000 Dalton. Strictly speaking, the ultrafiltration
membrane has a filtration pore size of 0.001 to 0.01 μm and a
molecular weight cutoff of 1,000 to 300,000 Dalton. A microporous
membrane with a filtration pore size greater than 0.01 μm or a
molecular weight cutoff greater than 300,000 Dalton should be
defined as a microfiltration membrane or a fine filtration
membrane.
Ultrafiltration membranes commonly used for water treatment have a
nominal molecular weight cutoff of 30,000-300,000 Dalton, while
ultrafiltration membranes with a molecular weight cutoff of
6,000-30,000 Dalton are mostly used in the separation,
concentration, sterilization and heat removal of materials.
The form of the ultrafiltration membrane can be divided into two
types, a plate type and a tube type. The tubular ultrafiltration
membrane is further classified into hollow fiber, capillary tube
and tube type according to the diameter of the tube. The
ultrafiltration membranes used for water treatment on the market
are basically capillary type, and the hollow fiber (inner diameter
0.1-0.5 mm) polyethylene or polypropylene microporous membrane used
in individual projects should actually belong to the
microfiltration membrane.
The assembly of ultrafiltration membrane filaments into a module
that can be coupled to an ultrafiltration system is referred to as
an ultrafiltration membrane module. The ultrafiltration membrane
modules are classified into three types: internal pressure type,
external pressure type and submerged type. The driving force of the
immersion ultrafiltration membrane filtration is the pressure
difference between the vacuum inside the membrane tube and the
atmospheric pressure. For ultrafiltration membranes with high
filtration accuracy, this pressure difference is usually not easy
to meet the required filtration driving force, so the submerged
component form is suitable for ultrafiltration membranes or
microfiltration membranes with low filtration precision. When the
external pressure type ultrafiltration is used in the forward and
reverse strokes, the flow rate of the liquid on the surface of the
membrane is extremely uneven, which affects the flushing effect on
the surface of the membrane. Therefore, the ultrafiltration
membrane commonly used for water treatment or the internal pressure
type component structure has advantages.
