In this paper, we propose a method of treating wastewater and sludge by microwave radiation. Many Russian scientists are studying microwave effect on the properties of water and sladge and they are solving the practical application of microwave technology in the treatment of wastewater and sludge. Research carried out at the department “Water supply and sanitation”, Tyumen State University of Architecture and Civil Engineering (Russia), confirm changing properties of water and sediments. So too studies confirmed the economic feasibility of the use of microwave radiation for treatment plants having small capacity.
