Efficient use of energy in wastewater treatment plants

Saving energy and increasing energy efficiency constitutes a rationalisation of energy use, which is becoming increasingly important in the context of sustainable development and security of energy supply, as well as the fight against global climate change. In line with the global trend, the issue of energy intensity of water and wastewater management is currently dynamically developing in terms of research. Consideration is therefore being given to the use of electricity in wastewater treatment systems, as well as the assessment of the energy efficiency of wastewater treatment plants. This paper presents the issues of electricity consumption in wastewater treatment systems and the possibilities of improving the energy efficiency of wastewater treatment plants.
