Four.Product Description:

1. In the process of ultrafiltration, the aqueous solution flows through the membrane surface under the pressure, and the solvent (water) and small molecule solute pervious membrane, which are smaller than the membrane hole, become the purification liquid (filter liquid). The solute and solute group larger than the membrane hole are retained and discharged with the water flow to become the concentrated liquid.The process of ultrafiltration is dynamic filtration, and the separation is completed in the flow state.Solute is deposited only on the membrane surface, the ultrafiltration rate attenuates to a certain extent and tends to equilibrium, and can be recovered by cleaning.

2. Ultrafiltration is a kind of pressurized membrane separation technology, that is, under a certain pressure, small molecules of solute and solvent pass through a special film with a certain aperture, while large molecules of solute cannot pass through and remain on one side of the film, so that large molecules of material have been partially purified.Ultrafiltration is one of the membrane separation techniques driven by pressure.The purpose is to separate large molecules from small molecules.

3. Hollow fiber ultrafiltration membrane:

(1) Ultrafiltration is a pressure-driven membrane separation process based on the principle of sieve separation. The filtration accuracy is within the range of 0.005-0.01 m, and it can effectively remove the particles, colloid, bacterial pad and polymer organic substances in the water.The hollow fiber ultrafiltration membrane treated by Luoyang Great spring water can be widely used in material separation, concentration and purification.Ultrafiltration process without phase transformation, operating at room temperature, especially suitable for the separation of heat sensitive substances, and has good temperature resistance, acid and alkali resistance and oxidation resistance, can be in 60?Below, the pH is 2-11 under the condition of long-term continuous use.

(2) Ultrafiltration, also known as overfiltration, is used to trap colloid sized particles in water, while water and low molecular weight solutes are allowed to pass through the membrane.The mechanism of ultrafiltration refers to the combined effects of mechanical screening on the membrane surface, blocking of membrane pores and adsorption on the membrane surface and membrane pores.

(3) The principle of ultrafiltration is also the principle of membrane separation process. Ultrafiltration uses a pressure active membrane to intercept the colloids, particles and substances with relatively high molecular weight in water under the action of external impetus (pressure), while the separation process of water and small solute particles through the membrane.It can be cut through the microporous membrane surfaceA substance with a molecular weight of 3x10000 -- 1x10000.

(4) When the treated water passes through the membrane surface at a certain flow rate under the action of external pressure, water molecules and substances with molecular weight less than 300-500 solute permeable molecular weight are 3x10000-1x10000.

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

(6) for hollow fiber ultrafiltration membranes, due to the membrane plate ultrafiltration device, intercept area is finite, hollow fiber ultrafiltration is in a hollow column, with many hollow fiber capillary, both ends are interlinked, the inner diameter of the tube in 0, 2 mm or so commonly, effective area can reach 1 square centimeters every fiber capillary like a miniature dialysis bag, greatly increased the surface area of infiltration, improves the speed of the ultrafiltration.

Vii. Water Quality standards:

1. Ultrafiltration process is carried out at room temperature under mild conditions without component damage, so it is particularly suitable for the separation, grading, concentration and enrichment of heat-sensitive substances, such as drugs, enzymes and fruit juices.

2. The process of ultrafiltration has no phase change, no heating, low energy consumption, no need to add chemical reagent, and no pollution. It is an energy-saving and environmental protection separation technology.

3. Ultrafiltration technology has high separation efficiency and is very effective in recovering trace components in dilute solution and concentrating low-concentration solution.

4. The ultrafiltration process only uses pressure as the power for membrane separation, so the separation device is simple, the process is short, the operation is simple, and the control and maintenance are easy.
