Water treatment in sewage plants with MBR technology
Studies indicate that during the coming years the presence of pure water will be very limited in many parts of the world, and the problem of scarcity of water and its low quality will face both developing and developed countries alike, while salinity increases in groundwater and the concentration of heavy metals is rising, this is considered one of the sources. Few pollutants to which water sources are exposed, but one of the most promising solutions that can get rid of most of the contaminants in the water is currently available, which is the MBR-Membrane Bioreactor treatment technology, as the treatment using biofilm technology is based on biological treatment and physical separation together and compared to methods For conventional treatment, biofilms provide ease of operation with high performance efficiency.
Biofilm treatment technology is a modern technology that started to spread during the last decade, but membranes were not used at the time due to its very high cost.
Recent developments in the manufacture of membranes have allowed the production of membranes with high efficiency and lower price, and with the increase in the prices of traditional treatment methods, the price of the membranes has become acceptable in the treatment of domestic wastewater and industrial wastewater. One of the most important advantages of biofilm technology is the small size of the plant compared to traditional methods, and there are no problems of sedimentation ponds as in treatment with activated collection basins or others.
Sometimes it does not need to be disinfected after treatment, as these membranes prevent the passage of bacteria, viruses, and other pathogens. The development of membrane science and technology has witnessed a long history in laboratory studies before its use in industrial applications. Today, however, it is widely accepted as one of the best available technology for treating water, especially wastewater
