Generally speaking, the pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fats, urea, etc.) and a large number of pathogenic microorganisms. These substances present in domestic sewage are easy to corrode and produce odor, so domestic sewage It must be treated before discharge, and ptfe sewage filter membrane is needed here.
High-concentration refractory organic wastewater refers to high organic matter concentration (measured as COD), generally above 2000mg/l, and some even as high as tens of thousands to hundreds of thousands of mg/liter; the so-called “difficult to degrade” “Degradation” refers to the low biodegradability of this type of wastewater (BOD5/COD values are generally below 0.3 or even lower, making it difficult to biodegrade. Therefore, the industry generally sets the COD concentration to be greater than 2000 mg/l and the BOD5/COD value to be less than 0.3 The organic wastewater is collectively called high-concentration refractory organic wastewater.
ptfe sewage filtration membrane has developed rapidly in the field of water treatment. It uses the micropore screening effect of the membrane to remove pollutants in the water. Filtration is performed. Commonly used membrane technologies in the advanced treatment of drinking water include microfiltration, ultrafiltration, reverse osmosis and nanofiltration. Among them, the performance of nanofiltration membranes is between reverse osmosis membranes and ultrafiltration membranes. Nanofiltration membrane pore size is 0.001~0.5μm, the operating pressure is 0.5~1.0MPa, and the membrane surface separation layer has a nanoscale microporous structure.
ptfe membrane manufacturer specializes in producing ptfe sewage filtration membrane, with A full set of advanced production equipment and technology, as well as an advanced clean room and an independent composite slitting workshop, ensure the production quality of ptfe membrane; the product materials produced are all imported raw materials, with high uniformity, stable performance and good breathability , the filtration efficiency can reach 99.999995%!
