Abstract: The energy and exergy analyses of the drying process of olive mill wastewater (OMW) using an indirect type natural convection solar dryer are presented. Olive mill wastewater gets sufficiently dried at temperatures between 34°C and 52°C. During the experimental process, air relative humidity did not exceed 58%, and solar radiation ranged from 227W/m2 to 825W/m2. Drying air mass flow was maintained within the interval 0.036–0.042kg/s. Under these experimental conditions, 2 days were needed to reduce the moisture content to approximately one-third of the original value, in particular from 3.153gwater/gdry matter down to 1.000gwater/gdry matter.
