UF Water Purifier Form a complete set of equipment
(1) the booster pump to force difference as a driving force for
ultrafiltration membrane filtration, when raw water pressure can
not meet the demand of filtering system need to increase the pump
pressure, in order to realize the ultrafiltration membrane
separation effect, due to the low working pressure ultrafiltration
membrane, generally less than o. 7 mpa, so in the system design,
generally choose centrifugal pump, the choice is the main basis of
centrifugal pump head, flow, pump body materials, the second is the
size of the pump, style and price, etc.
(1) the selection of head and flow according to the design of the
ultrafiltration system need water inlet working pressure, cross
membrane pressure difference and water flow, to choose the pump
head and flow.Generally, the head and flow of the selected pump
should be equal to or slightly greater than the designed water
supply and working pressure to meet the normal operation of the
ultrafiltration system.
The choice of pump body material according to the quality of raw
water to choose the appropriate pump body material to reduce the
cost of investment, the material can not produce any reaction with
raw water ingredients, also can not have dissolved phenomenon.When
the pH of raw water is 6.5 ~ 8.5 can choose cast iron pump
body;When the raw water for sea water, should choose the seawater
corrosion resistant plastic pump body;Pharmaceutical and food
industry water treatment but generally choose to use stainless
steel pump body.
UF Water Purifier classification
The filter membrane can be classified into microporous filtration,
ultrafiltration and reverse osmosis according to the applied
operating pressure and the average pore diameter of the membrane
used. The operating pressure used for microfiltration is typically
less than 2 x 10^5 Pa, and the membrane has an average pore size of
500 angstroms to 14 microns for separating large particles,
bacteria and contaminants. The operating pressure for
ultrafiltration is 1 x 10^5 Pa to 6 x 10^5 Pa, and the membrane has
an average pore diameter of 10 to 100 angstroms for separating
macromolecular solutes. The operating pressure used for reverse
osmosis is larger than that of ultrafiltration, often reaching
20×10^5 Pa~70×10^5 Pa. The average pore size of the membrane is the
smallest, generally less than 10 angstroms, for separating small
molecular solute, such as seawater desalting. , high purity water,
etc.
UF Water Purifier application
The ultrafiltration membrane has a minimum molecular weight cutoff
of 500 Daltons and can be used in biopharmaceuticals to separate
proteins, enzymes, nucleic acids, polysaccharides, peptides,
antibiotics, viruses, and the like. The advantage of
ultrafiltration is that there is no phase transfer, no need to add
any strong chemicals, it can be operated at low temperature, the
filtration rate is faster, and it is easy to perform aseptic
processing. All of this simplifies the separation operation and
avoids loss of vitality and denaturation of the biologically active
material.
Because of its many advantages, ultrafiltration technology is often
used as:
(1) Desalination and concentration of macromolecular substances,
and exchange equilibrium of solvent systems of macromolecular
substances.
(2) Fractionation of macromolecular substances.
(3) Depyrogen treatment of biochemical preparations or other
preparations.
Ultrafiltration technology has become an indispensable tool in the
pharmaceutical, food, electronics and environmental protection
fields.
