Industrial ultrafiltration membrane water treatment equipment purified water system ZZ

The filter is a device that uses ultrafiltration technology to purify water. The difference from other water purification equipment is the use of ultrafiltration membranes. Ultrafiltration membrane is a kind of microporous filtration membrane with consistent pore size specifications and rated pore size range of 0.01-0.001 microns. The membrane filtration method using ultrafiltration membrane with pressure difference as the driving force is ultrafiltration membrane filtration. 

The membrane in the ultrafiltration equipment is a microporous filtration membrane with the same pore size and the rated pore size range of 0.001-0.02 microns. The membrane filtration method using ultrafiltration membrane with pressure difference as the driving force is ultrafiltration membrane filtration. Ultrafiltration membranes are mostly made of acetate fibers or polymer materials with similar properties. It is suitable for the separation and concentration of solutes in the processing solution, and is also often used for the separation of colloidal suspensions that are difficult to complete with other separation technologies. Its application fields are constantly expanding. Membrane filtration driven by pressure difference can be divided into three types: ultrafiltration membrane filtration, microporous membrane filtration and reverse osmosis membrane filtration. Their distinction is based on the size or molecular weight of small particles that the film can retain.

The filtration accuracy is within the range of 0.005-0.01μm, which can effectively remove particles, colloids, worms, heat sources and polymer organic substances in the water. It can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase inversion and is operated at room 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 continuous for a long time under the conditions of below 60℃ and pH 2-11 use.

The form of ultrafiltration membrane can be divided into two types: plate type and tube type. Tubular ultrafiltration membranes are divided into hollow fiber, capillary and tubular types according to their diameter. The ultrafiltration membranes used for water treatment in the market are basically capillary type. The hollow fiber (inner diameter 0.1-0.5mm) polyethylene or polypropylene microporous membranes used in individual projects should actually be microfiltration membranes.

The special ultrafiltration equipment for pollution engineering removes impurity particles of a certain size in the water by means of physical retention. Driven by pressure, water, organic low molecules, inorganic ions and other small-sized substances in the solution can reach the other side of the membrane through the micropores on the fiber wall, and large-sized bacteria, colloids, particles, and organic macromolecules in the solution The substance cannot penetrate the fiber wall and is retained, so as to achieve the purpose of sieving different components in the solution.

The combination of ultrafiltration membrane filaments into a component that can be connected to an ultrafiltration system is called an ultrafiltration membrane module. Ultrafiltration membrane modules are divided into three types: internal pressure type, external pressure type and submerged type. The driving force of submerged ultrafiltration membrane filtration is the pressure difference between the vacuum inside the membrane tube and the atmospheric pressure.
