Evaluation of solar sludge drying alternatives by costs

Thermal drying is a common method to reach above 90% dry solids content (DS) in sludge However thermal drying requires high amount of energy and can be expensive A greenhouse solar dryer (GSD) can be a cost-effective substitute if the drying performance which is typically 70% DS can be increased by additional heat In this study feasibility of GSD supported with solar panels is evaluated

Integration of Green Energy and Advanced Energy

Mathioudakis et al studied the drying of sludge in Greece using a heat collecting and storage solar drying device The results show that the sludge moisture content needed to be reduced from 85–6% for 7–12 days in the summer and reduced to 10% for 9–33 days in the autumn at the same time the volume of sludge was reduced to 15–20% If a solar hot water circulation system was

SOLAR DRYING OF SEWAGE SLUDGE

SOLAR DRYING OF SEWAGE SLUDGE End product of all types of sewage works is the cleared water and a more or less liquid mass: the sewage sludge The volume of the untreated sludge is enormous as it still contains over 95% of water Using different mechanical methods this volume can be reduced sig-nificantly but the water content can only be reduced – depending on the system and investment
