60T Per Hour UF Membrane Filter Ultrafiltration Water Purifier

Application fields of ultrafiltration water treatment system:
Ultrafiltration membranes have been widely used in advanced treatment of industrial wastewater and process water, such as concentration, purification and separation of macromolecular substances in chemical, food and pharmaceutical industries, sterilization of biological solutions, separation of dyes in printing and dyeing wastewater, and petrochemical wastewater. The recovery of glycerol in the photochemical wastewater, the recovery of silver and the preparation of ultrapure water, etc. In addition, it can also be used for sludge concentration and dewatering

Technical Specifications of Ultrafiltration Water Treatment System

Working Principle of Ultrafiltration Water Treatment System

Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, small solute and solvent pass through a special membrane with a certain aperture, while the large molecule solute cannot pass through, stay on one side of the membrane, so that the large molecule material is partially purified.

Performance characterization of ultrafiltration water treatment:
Performance is expressed in terms of pure water permeability in square meters per hour and molecular weight cut-off and cut-off percentage. The higher the permeability of pure water, the better, and the retention rate is generally required to be >99%. High-quality ultrafiltration membranes have a large pore density and a narrow pore size distribution.



The similarities and differences between ultrafiltration water treatment system and reverse osmosis water treatment system:
Both ultrafiltration and reverse osmosis are pressure-driven membrane separation technologies. The application range of the two is crossed, and it is difficult to demarcate; the membranes used are semi-permeable membranes with asymmetric microporous structure, with the same membrane materials and similar membrane preparation methods. There are similar mechanisms and functions; the separation of the two is a process in which the solvent passes through the membrane and the solute is retained by the membrane.
The main difference between ultrafiltration and reverse osmosis is: ① The structure of the membrane is different. Generally, the ultrafiltration membrane is loose, the permeable flux is large, and the salt removal rate is low, while the reverse osmosis membrane is dense, the permeable flux is small, and it has selective permeability. ②The permeation mechanism of the membrane is different. The separation of the ultrafiltration membrane is mainly sieving, while the separation process of the reverse osmosis membrane is also accompanied by complex physical and chemical effects. ③ Different working pressures, the ultrafiltration process can be carried out at a lower operating pressure, and the operating pressure range is generally 0.1-0.5MPa, while reverse osmosis must apply a higher external pressure in order to overcome the osmotic pressure, and its operating pressure range is 2. ~10MPa. ④ Different solutes are retained. Ultrafiltration retains macromolecular solutes with a molecular weight greater than 500. The reverse osmosis generally separates sugars, salts and other substances with a relative molecular weight below 500.
