Access to an improved water supply and sanitation has in general increased across Europe, resulting in an 80% decrease in diarrheal disease in young children from 1995 to 2005.
Nevertheless 120 million people do not have access to safe drinking-water now in the European Region.

water 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 have lo
