    The aim of presented thesis is modeling and prediction of temporal variability of biogas in the three selected municipal wastewater treatment plants in Krosno, Rzeszow and Krakow. The data were prepared and modeled in Statistica's Statsoft program on the basis of materials obtained from municipal wastewater plants. Modeling was done by using stepwise regression and neural networks. Next stage was prediction of data. The accuracy of prediction was estimated by four measures: MAPE, Theil coefficient, Janus coefficient and RMSPE. Similar models could be used in municipal wastewater treatment plants to estimate the amount of biogas production. It will be used to product heat energy and electrical power which consequently is to reduce the wastewater treatment plants requirements for the outside energy intake.
