Water Purifier Plant Ultrafiltration Water Treatment System UF Filter Membrane

What are the applications of Ultrafiltration Water Treatment System?

The ultrafiltration membrane has a minimum molecular weight of 500 Dalton, which can be used to separate proteins, enzymes, nucleic acids, polysaccharides, peptides, antibiotics, viruses and so on in biopharmaceuticals. The advantages of ultrafiltration are no phase transfer, no need to add any strong chemicals, can be operated at low temperature, fast filtration rate, easy to do aseptic treatment, etc. All of these can simplify the separation operation and avoid the loss of vitality and denaturation of bioactive substances.

Often used as:

(1) Desalination and concentration of macromolecular substances, and exchange equilibrium of solvent system of macromolecular substances.

(2) Fractional separation of macromolecules.

(3) pyrogenation of biochemical agents or other agents.

Ultrafiltration technology has become an indispensable and powerful tool in pharmaceutical industry, food industry, electronic industry and environmental protection

How does an Ultrafiltration Water Treatment System work?

The principle of ultrafiltration is not complicated. In the process of ultrafiltration, concentration polarization occurs due to the continuous accumulation of trapped impurities on the membrane surface. When the solute concentration on the membrane surface reaches a certain limit, the gel layer will be formed, which makes the membrane permeable water decrease sharply, which restricts the application of ultrafiltration to a certain extent. Therefore, experiments are needed to determine the best process and operating conditions, minimize the influence of concentration polarization, and make ultrafiltration a reliable method of reverse osmosis pretreatment.

Process flow of Ultrafiltration Water Treatment System

Raw water → original water tank (supplied by the buyer)→ raw water pump → disc filter → activated carbon filter →5μm security filter → ultrafiltration device → pure water tank (supplied by the buyer)→ water supply point

Ultrafiltration Water Treatment System filtration four steps:

1. Sand filter: use 0.5-1 mm sand medium. The filter can be as small as 200 microns in size. Some large suspended solids such as suspended solids, rust, mud, impurities, etc. can be trapped by the medium bed. And removed from the water.

2, activated carbon filter: can absorb some organic matter, dissolved air, smell and color substances.

3, micron filter: use 5-20 micron precipitate cartridge filter/bag filter, remove the suspended solid through the pretreatment. So the RO entrance is more secure.

4. Ultrafiltration system (UF membrane intercepts most ions. Demineralization/desalination, etc. The output will be pure water.

Ultrafiltration water treatment system is easy to operate, low cost, does not need to increase any chemical reagents, especially the experimental conditions of ultrafiltration technology is mild, compared with evaporation, freeze drying, no phase change, and does not cause temperature, pH changes, so it can prevent the degeneration, inactivation and autolysis of biological macromolecules. In the preparation of biological macromolecules, ultrafiltration is mainly used for desalination, dehydration and concentration of biological macromolecules.
