The paper presents a case study on wastewater sludge drying in a vacuum filter. Using finite element analysis it is estimated the variation with cake height, along its centerline, of temperature, liquid and gaseous phase ratios. Numerical results are estimated after 30 hours of drying at different temperatures (60°C, 80°C and 100°C), considering a sludge initial moisture content of 20%.
