Sludge treatment − solar dryers | The MBR Site
They take the form of large greenhouses into which the sludge is fed either continuously or in batches. Solar drying provides the lowest energy demand of all dryers, as low as 50 kWh/t.
However, it presents challenges, particularly in terms of efficiency and drying time. In this context, the present study explores the drying performances of an innovative Combined Solar Greenhouse Dryer (CSGD) for sewage sludge. The system integrates rock bed storage (RBS), a solar air collector (SAC), and a solar greenhouse dryer (SGD).

Recently, solar drying processes, often performed through solar greenhouses, received interest due to their limited energy requirement and renewable energy exploitation. The dried sludge shows significant volume and mass reductions, reducing transportation and disposal costs.
They take the form of large greenhouses into which the sludge is fed either continuously or in batches. Solar drying provides the lowest energy demand of all dryers, as low as 50 kWh/t. Although heating is provided at zero or minimal cost, energy is demanded by both the mechanical agitation of the sludge solids and deodorisation of the exhaust air.
