Research on the Treatment of Wastewater and Possibilities for Optimizing the Technological Route

Abstract Water is one of the basic resources for all living things on Earth. From historical studies it can be seen that human settlements appeared near watercourses, because no human activity is possible without water. The Earth’s surface is covered in 78% water, which seems encouraging, but of this amount, only about 2.5% is considered drinkable. This distribution shows us the limiting nature of drinking water resources, which requires efficient management of this resource. Along with the development of mankind, water was used more and more in various domestic, industrial, energetic, and other activities, so that its quality was affected. Under such conditions, it has become absolutely necessary to apply wastewater treatment methods. By applying wastewater treatment methods, the aim is to improve water quality, so that it can be discharged into the emissary without being harmful to various environmental factors. This paper presents the classical methods of wastewater treatment and the possibility of optimizing the technological treatment route in a wastewater treatment plant.
