4、 Product function description:

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.

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) 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 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, and can be used continuously for a long time under the condition of 60 ° C and pH 2-11.

gd55光大彩票(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.

gd55光大彩票(3) The principle of ultrafiltration is also a principle of membrane separation process. Ultrafiltration uses a kind of pressure active membrane to intercept substances with relatively high colloid, particle 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. Materials with molecular weight of 3 × 10000-1 × 10000 can be retained by microporous screening on the membrane surface.

(4) When the treated water passes through the membrane surface at a certain flow rate under the action of external pressure, water molecules and solute with molecular weight less than 300-500 have a molecular weight of 3 × 10000-1 × 10000.

(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 into it is a reliable pretreatment method of ro.

(6) For the hollow fiber ultrafiltration membrane, due to 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 1 square centimeter. Each capillary tube is like a micro dialysis bag, greatly increasing the surface area of penetration, The speed of ultrafiltration is improved. 　

5. Features:

◇ 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.

◇ The ultrafiltration process does not change phase, does not need heating, low energy consumption, does not need to add chemical reagents, and is a kind of energy-saving and environmental protection separation technology.

gd55光大彩票◇ The ultrafiltration technology has high separation efficiency and is very effective for the recovery of trace components in dilute solution and concentration of low concentration solution.

gd55光大彩票◇ The ultrafiltration process only uses the 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.
