gd55光大彩票4、 Product function description:

1. In the process of ultrafiltration, the aqueous solution flows through the membrane surface under the pressure. The solvent (water) and small molecule solute which are smaller than the membrane pore will permeate through the membrane and become the purification solution (filter liquid). 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 membrane surface, and the ultrafiltration rate decreased to a certain extent and tended to balance, and could be recovered by cleaning.

gd55光大彩票2. Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, the small molecule solute and solvent pass through a special membrane with a certain pore diameter, while the macromolecular solute can not pass through and stay on one side of the membrane, so that the macromolecular substance is partially purified. Ultrafiltration is one of membrane separation technologies driven by pressure. The aim is to separate macromolecules from small molecules.

3. Hollow fiber ultrafiltration membrane:

gd55光大彩票(1) Ultrafiltration is a kind of membrane separation process, which takes screening as separation principle and pressure as driving force. The filtration precision is in the range of 0.005-0.01 μ m, which can effectively remove particles, colloids, bacterial cushion and polymer organic substances in water. Luoyang Daquan water treatment hollow fiber ultrafiltration membrane can be widely used in separation, concentration and purification of substances. The ultrafiltration process has no phase transformation and operates at normal temperature. It 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 conditions of pH 2-11 and below 60 ℃.

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

gd55光大彩票(3) The principle of ultrafiltration is also a principle of membrane separation process. Ultrafiltration uses a pressure activated membrane to intercept colloids, particles and substances with relatively high molecular weight in water under the action of external driving force (pressure), while water and small solute particles pass through the membrane separation process. Through the microporous screening on the surface of the membrane, it can be cut off

The molecular weight is 3 × 10 000-1 × 10 000.

(4) When The treated water passes through The membrane surface at a certain flow rate under The action of external pressure, The water molecules and solutes with molecular weight less than 300-500 penetrate The molecular weight is 3 × 10,000-1 × 10,000.

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 optimal process and operating conditions, minimize the influence of concentration polarization, and make ultrafiltration a reliable pretreatment method for reverse osmosis.

gd55光大彩票(6) For the hollow fiber ultrafiltration membrane, due to the membrane plate ultrafiltration device, the interception area is limited. Hollow fiber capillary tubes are installed in a hollow column with two ends connected. The inner diameter of the tube is generally about 0,2 mm, and the effective area can reach 1 square centimeter. Each fiber capillary is like a micro dialysis bag, which greatly increases the surface area of permeation, The speed of ultrafiltration was improved.
