Why MBR membranes can treat domestic wastewater

Mondo Social Updated on 2024-01-27

MBR membrane is a new type of water treatment technology, which has very outstanding advantages for sewage treatment. It adopts the characteristics of membrane separation technology with high separation accuracy and good filtration effect, which can separate and remove pollutants such as ammonia nitrogen compounds, phosphides, microorganisms, organic matter, toxic and harmful chemicals contained in domestic sewage. MBR membrane has been applied in small and medium-sized urban sewage treatment plants, and is one of the hot sewage technologies in the field of environmental protection.

MBR membrane is divided into flat membrane and curtain membrane, which can be flexibly selected according to different sewage treatment needs. On the whole, the advantages of MBR membranes are mainly divided into:

1.Chemically very stable. Chemical stability is a very important performance of sewage treatment technology, the composition of domestic sewage is complex and the quantity is huge, the rich compound content in the water is prone to chemical reaction with the treatment materials, if the treatment materials used are not appropriate, other pollutants may be produced, causing serious impact on the environment. In addition, it also increases the burden of cleaning and maintenance. The MBR membrane is made of PVDF material, which has good resistance and is chemically stable

2.Strong anti-pollution ability. The MBR membrane has a smooth surface, high porosity and uniform distribution, and a large membrane flux, which can effectively prevent the accumulation of sludge and various suspended solids, compounds and waste residues contained in domestic sewage in the membrane channel, and avoid the problem of compaction that is easy to occur in traditional domestic sewage treatment components

3.High mechanical strength. The membrane filament of MBR membrane is equipped with strong ribs, which is very flexible and has strong tensile resistance, and has good durability when operating in an aeration cleaning environment, which effectively prevents the membrane filament from being damaged during operation and cleaning. At the same time, it also eliminates the phenomenon of broken filaments of traditional components, and has a longer service life

4.Low cost. The MBR membrane consumes less energy during operation, and at the same time, because it does not require the addition of chemical reagents, it can completely ignore the consumption of chemical reagents, which greatly saves the cost of domestic sewage treatment plants.

With the development of social economy, people pay more and more attention to environmental issues. MBR membrane technology is a good helper for domestic sewage treatment in sewage treatment plants, which improves the efficiency of domestic sewage treatment and contributes to ecological environmental protection.
