Covered solar drying has given better results than open solar drying. However, the origin of the wastewater sludge affects the obtained results. Alternatively, modeling drying systems was effectuated using heat and mass balances, applied for the air and the dried product. Solar drying of wastewater sludge has given satisfactory results. 1.
Mathioudakis et al. propose drying wastewater sludge using two solar drying plants. The sludge was obtained from WWTP of Komotini in Greece. Several batches of sludge were sampled after thickening and dewatering.
After application of solar drying, the dry sludge has attained, in summer, the following values: 2 × 10 4 CFU g −1 DS as total coliform and 10 3 CFU g −1 DS as fecal coliform. These values were respectively 2 × 10 6 CFU g −1 DS and 8 × 10 5 CFU g −1 DS in autumn.
Technologies and methods for energy storage in solar drying Thermal Energy Storage: Thermal energy storage techniques, such as phase change materials (PCMs) or heat storage in rocks or water, can be used with solar drying systems. This stored thermal energy can then be released during periods of insufficient sunlight.
The structure was fitted with ventilation system in order to provide a uniform distribution of the air over the surface of the dried sludge through a number of blowers. Also, a sludge shuffling system was installed. The solar drying system has an average daily drying rate of 8.12 kg H 2 O/m 2 d.
