The core technology of membrane separation equipment is membrane separation technology, Ultrafiltration membrane manufacturer The separation membrane is a material with selective separation function. Its working principle is the physical mechanical screening principle. The separation process is a process that uses the selective separation mechanism of the membrane to realize the separation of different components of the feed liquid or the concentration of effective components.
Membrane separation technology equipment is different from traditional filtration in that membrane can be selectively separated within the molecular range, and the cross flow operation process of membrane can solve the problem of pollution and blockage, which is a scientific and advanced separation technology and process.
Equipment used for ultrafiltration, reverse osmosis, gas osmosis separation, dialysis, electrodialysis, liquid membrane separation and a series of membrane separation operations. Due to the characteristics of membrane configuration and separation process, there are also many types of equipment. Sometimes, they are called ultrafiltration, osmosis, dialysis, electrodialysis or desalinator according to the purpose or use of the process. Their future development trend is automation and simplicity.
Membrane separation equipment has been widely used in the society, but many consumers in the society are not clear about the common equipment of membrane separation equipment, so today let the experts of membrane separation equipment introduce the common equipment.
The common ones are microfiltration. Generally, the pore diameter of the membrane is greater than 0.1~5.0 μ m. However, the pressure of this equipment during operation reaches about 300kPa. Generally, it is mainly used to separate the finer particles and coarsely dispersed substances in sewage, and it is generally used as pretreatment of other treatment processes.
Generally, the pore diameter of ultrafiltration membrane is 0.01~0.1 μ m. However, the pressure during operation is 150~700kPa. Generally, it is mainly used for fine particles in sewage and emulsified oil. Generally, some useful substances are not recycled, such as coatings recycled from electroplated coatings. If polyvinyl alcohol can be recycled in the chemical fiber industry. So we must pay attention to the skills.
One is the nanofilter, whose membrane aperture is 0.001~0.01 μ m. However, the pressure suitable for work is 500~1000kPa. Nanofilters are mainly used for organic compounds with sewage quality of 200-500. In fact, the main separation is multi dielectric ions and chroma particles.
