Application fields of ultrafiltration equipment

Nov 15, 2019

Ultrafiltration membranes are used in a wide range of applications. Filtration equipment can be used in the filtration industry. The basic filtration industry is as follows: reverse osmosis pretreatment and ultrapure water terminal treatment in pure water and ultrapure water preparation processes; Industrial water used to separate bacteria, heat sources, colloids, suspended impurities and macromolecular organics; drinking water, mineral water purification; fermentation, enzyme preparation industry, pharmaceutical industry concentration, purification and clarification; juice concentration, separation; soybeans, dairy products, Separation, concentration and clarification of sugar industry, alcohol, tea juice, vinegar, etc.; purification and recovery of industrial wastewater and domestic sewage; recovery of electrophoretic paint.

Ultrafiltration membrane separation can replace the natural sedimentation in traditional processes, plate and frame filtration, vacuum drum, centrifugal separation, solvent extraction, resin purification, activated carbon decolorization and other processes. The process is normal temperature operation, no phase change, no secondary pollution.

A microporous membrane with a uniform pore size and a nominal pore size range of 0.001-0.02 microns. The membrane filtration method using an ultrafiltration membrane with a pressure difference as a driving force is an ultrafiltration membrane filtration. Membrane filtration driven by pressure difference can be divided into three types: ultrafiltration membrane filtration, microporous membrane filtration and reverse osmosis membrane filtration. The ultrafiltration membrane can be used in the form of a flat membrane, a roll membrane, a tubular membrane or a hollow fiber membrane, and is widely used in, for example, the pharmaceutical industry, the food industry, environmental engineering, and the like. We all know that the sieve is used to sieve things, it can release small objects, and the larger ones are left behind. However, have you heard of a sieve that can sieve molecules? Ultra-Film - This super sieve separates molecular sieves of varying sizes! So, what exactly is an ultrafiltration membrane? The ultrafiltration membrane is a porous membrane with super "sieving" separation function. Its aperture is only a few nanometers to tens of nanometers, which means that there is only one hair strand! By applying a suitable pressure to one side of the membrane, solute molecules larger than the pore size can be sieved to separate particles having a molecular weight greater than 500 Daltons and a particle size greater than 2-20 nm.
