wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to ha

and society meet a range of energy and environmental challenges.
One example can be found in the area of water use and purification, where GE scientists are investigating new membrane materials and innovative advanced separation technologies. These allow for further treatment and better performance of on-site wastewater reuse and recycling for the industrial, agriculture and municipal sectors.
Nowadays, ‘eutrophication’ presents as one of the most serious ecological problems of open water sources such as lakes, oceans and reservoirs. It can be occurs naturally over centuries as lakes age and filled in with sediments, or acid rain. However, it has been rapidly increasing caused by human activities like fertilizers, municipal sewage, and wastewater from the factory. The Baltic Sea is
