UF membrane

UF membrane : The filtration accuracy is 0.001-0.1 microns, which belongs to one of the high-tech technologies of the 21st century. It is a membrane separation technology using differential pressure, which can filter out the harmful substances such as rust, sediment, suspended matter, colloids, bacteria, macromolecular organic matter, and retain some mineral elements that are beneficial to the human body.

Product Description

UF membrane The ultrafiltration membrane has an asymmetrical microporous structure and is divided into two layers: the upper layer is a functional layer, which has dense micropores and the function of intercepting macromolecules, and its pore size is 1-20nm; the lower layer has a support layer with a large through-hole structure, which increases The role of large film strength.
The functional layer is thin and the water permeable flux is large. Generally, various types of components such as tube type, plate type, roll type, capillary type, etc. are made first, and then multiple components are assembled together to increase the filtration area. The membrane ultrafiltration process is essentially a mechanical screening process, and the size of the pores on the membrane surface is the most important controlling factor. The solute (polymer or solution) that can be separated by the ultrafiltration membrane is a molecule with a size of 1-30nm. In addition to the characteristics of the membrane, the substances it rejects are also related to the shape, size, flexibility and operating conditions of the substance molecules. Cellophane and nitrocellulose membranes used in early ultrafiltration membranes

Applicable Industry

Ultrafiltration membranes have been widely used in the advanced treatment of industrial wastewater and process water, such as the concentration, purification and separation of macromolecular substances in the chemical, food and pharmaceutical industries, the sterilization of biological solutions, the separation of dyes in printing and dyeing wastewater, and petrochemical wastewater. Recovery of glycerin, silver recovery from photographic chemical wastewater, and preparation of ultra-pure water. In addition, it can also be used for sludge thickening and dewatering, etc.

Stark Advantage

High filtration accuracy, good effluentwater quality (turbidity less than 0.1NTU)
Strong hydrophilicity (contact Angle aslow as 47 " not easy to plug, flux easy torecover)
High membrane strength and goodtoughness(membrane elongation ofmore than 50%)
Low pressure and high flux (the designflux can be met at a very low film pressuredifference)
Good chemical stability (membranecomponent after 20 times of acid andalkali chemical cleaning, the performanceremainsunchanged)
Strong anti-pollution ability (cleaningcycle is 30%longer than peers, membraneflux recovery effect is good)
External pressure use, strong
contaminant capacity, wider inlet waterquality
The standard accessory connectionmethod greatly improves the convenienceof
