Energetic optimisation of WWTP´s operation

By Veronika Čížová

Abstract

The reduction in energy consumption is nowadays of increasing importance also within the field of waste water treatment. In combination with increasing requirements for the WWTP (waste water treatment plant) outlet quality, the energy optimization becomes very challenging for the plants operators. This thesis presents possible approaches to the energy optimization and summarizes technologies and measures, where some of them are in the research phase while others are already implemented successfully. In particular, the contribution of the activation tanks aeration process to the overall energy consumption of a plant is highlighted. A change in the aeration control is tested using a mathematical model of WWTP in Mikulov, South Moravia in Czech Republic. In the new setting the aeration is regulated based on the concentration of nitrogen compounds in the activation tank. There is also a brief survey of the energy consumption of the plant and an outline of other possible energy conservation measures
