When summer comes, heavy rains often occur. Large amounts of precipitation will put great pressure on urban roads and rivers, and at the same time, various pollutants on the road surface will Some objects piled in the open air are likely to be carried into the sewers and flow into the rivers along with the erosion of heavy rains, causing a large degree of pollution to the rivers. As the saying goes, water is the source of life. Without water, we are like fish without water. It is difficult to survive. Therefore, sewage treatment is very important. We have to talk about ptfe sewage filtration membrane. role in sewage treatment.
Membrane technology is recognized as one of the most promising high technologies in the sewage treatment industry. In recent years, through diffusion theorem, membrane dialysis phenomenon, osmotic pressure principle and other research have laid a solid foundation for the development of membrane technology. At present, membrane technology mainly has the following seven forms: 1. Reverse osmosis membrane technology 2. Nanofiltration membrane technology 3. Microfiltration (MF) membrane technology 4. Ultrafiltration (UF) membrane technology. 5. Electrodialysis (ED) membrane technology 6. Bipolar membrane (BPM) technology 7. Pervaporation (PV) membrane technology After more than 50 years of development, my country’s membrane industry has entered a period of rapid development. In seawater desalination and sewage treatment, The scope of application in treatment, wastewater recycling, and pharmaceutical and food industries is rapidly expanding.
The currently independently developed ptfe sewage filtration membrane is the core material of sewage treatment membrane technology. The membrane is manufactured using a biaxial stretching process, with a porosity of over 80% and a pore size of 0.1μm-1μm. The pore size of ptfe sewage filtration membrane is adjustable to obtain different bubble point pressures and meet different filtration precisions. , with broad chemical applicability, biosafety and pyrogen control, available in both hydrophilic and hydrophobic versions. The filtration resistance is extremely low and is generally praised by customers! Interested parties can enter the store for consultation and purchase!
