4、 Product function description:

gd55光大彩票1. In the process of ultrafiltration, under the pressure, the aqueous solution flows through the membrane surface, and the solvent (water) and small molecular solute permeable membrane smaller than the membrane pore become the purification solution (filter solution). The solute and solute group larger than the membrane pore are intercepted and discharged with the water flow to become the concentrated solution. The ultrafiltration process is dynamic filtration, and the separation is completed in the flow state. The solute only deposited on the surface of the membrane, and the ultrafiltration rate decreased to a certain extent and tended to balance, and could be recovered by cleaning.

2. Ultrafiltration is a kind of pressurized membrane separation technology, that is to say, under a certain pressure, the small molecule solute and solvent pass through a special membrane with a certain pore diameter, while the large molecule solute cannot pass through, and remains on one side of the membrane, so that the large molecule material is partially purified. Ultrafiltration is one of the membrane separation technologies driven by pressure. The aim is to separate macromolecules from micromolecules.

1. Hollow fiber ultrafiltration membrane:

(1) Ultrafiltration is a membrane separation process with screening as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01 μ m, which can effectively remove the particles, colloids, bacterial cushion and high molecular organic substances in water. Hollow fiber ultrafiltration membrane can be widely used in separation, concentration and purification of substances. The ultrafiltration process has no phase transformation and is operated at normal temperature, which is particularly suitable for the separation of heat sensitive substances. It has good temperature resistance, acid and alkali resistance and oxidation resistance. It can be used continuously for a long time under the condition of 60 ° C and pH 2-11.

(2) Ultrafiltration, also known as ultrafiltration, is used to intercept colloidal sized particles in water, while water and low molecular weight solutes are allowed to penetrate the membrane. The mechanism of ultrafiltration refers to the comprehensive effect of mechanical screening on the membrane surface, membrane pore blocking and membrane surface and membrane pore adsorption, with screening as the main mechanism.

(3) The principle of ultrafiltration is also a principle of membrane separation process. Ultrafiltration uses a kind of pressure active membrane to intercept the substances with relatively high colloid, particles and molecular weight in water under the action of external driving force (pressure), while the separation process of water and small solute particles passing through the membrane. It can be cut through the microporous screening on the membrane surface

gd55光大彩票Leave a material with molecular weight of 3 × 10000-1 × 10000.

(4) Water molecules and solutes with molecular weights less than 300-500 permeate when treated water passes through the membrane surface at a certain flow rate under external pressure leave a material with molecular weight of 3 × 10000-1 × 10000.

gd55光大彩票(5) The principle of ultrafiltration is not complicated. During ultrafiltration, due to the accumulation of trapped impurities on the membrane surface, a concentration polarization phenomenon will occur. When the solute concentration reaches a certain limit, the gel layer will be formed, resulting in a sharp decrease in the permeability of the membrane, which limits the application of ultrafiltration. Therefore, it is necessary to study through experiments to determine the best process and operation conditions, minimize the influence of concentration polarization, and make ultrafiltration a reliable pretreatment method of reverse osmosis.

(6) For the hollow fiber ultrafiltration membrane, because of the membrane plate ultrafiltration device, the interception area is limited. The hollow fiber ultrafiltration is equipped with many capillary tubes in a hollow column. The two ends are connected. The inner diameter of the tube is generally about 0,2mm, and the effective area can reach 1m2. Each capillary tube is like a micro dialysis bag, which greatly increases the surface area of penetration, The speed of ultrafiltration is improved.

gd55光大彩票7、 Water quality standard:

1. The ultrafiltration process is carried out at room temperature under mild conditions without component damage, so it is particularly suitable for the separation, classification, concentration and enrichment of heat sensitive substances, such as drugs, enzymes, juice, etc.

gd55光大彩票2. Ultrafiltration process does not change phase, does not need heating, low energy consumption, does not need to add chemical reagents, no pollution, is an energy-saving and environmental protection separation technology.

gd55光大彩票3. Ultrafiltration technology has high separation efficiency, which is very effective for the recovery of trace components in dilute solution and concentration of low concentration solution.

4. The ultrafiltration process only uses pressure as the power of membrane separation, so the separation device is simple, the process is short, the operation is simple, easy to control and maintain.
