Energy balance in water treatment plants

This article deals with the reduction of the energy consumption of water treatment plants through the production of their own electricity and their optimization using new, more efficient energy technologies and approaches. The main objective of the work was to present the issue of high electricity consumption of waterworks, its solution, and the technologies used for optimization. These technologies have already been proven worldwide but remain underutilized. By their extension and appropriate use, significant and proven savings can be achieved. The second task was to propose a model of a photovoltaic power plant with a battery system designed for a water pumping station, based on data obtained by monitoring electricity consumption for a whole year. The model was created using the SAM (System Advisor Model) software from the US National Renewable Energy Laboratory (NREL) and is used to demonstrate possible solutions. Basically, the aim of this work was to present the problem of high electricity consumption of waterworks and the possibilities to reduce it.
