Solar Sludge Dryer

Huber solar active dryer srt.

Solar sludge dryer.

The final dry content of the pellets is between 65 and 90. The basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation. Sludge can be dried in batches using a semi continuous process by means of a fully. It significantly reduces the volume and weight of the sludge so that it is easier to recover.

Three processes are available. Using the sun as the main energy source the sludge is dried in a greenhouse and a scarifying machine breaks up the sludge into carbon neutral and odorless. The basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation. Huber solar active dryer srt.

Direct drying by the belt dryer. A special sludge turning system performs both spreading and turning of the sludge as well as its transport from one side to the other. The huber solar regenerative sludge dryer srt is able to meet the most different specific customer requirements whether as a pure solar dryer or all year round dryer operated with additional heat. The combined sludge turning and transporting system is at the heart of the drying plant.

Solar sludge drying is an ideal method of reducing sludge volumes and disposal costs particularly in the australian climate. Heliantis solar dryer transforms any type of dewatered sludge 15 minimum dry content into a dry granulated product with a dry solids content that can be adjusted from 35 to 75. The sludge is transported. Also the automation degree of sewage sludge feeding and removal is variable.

Thermal drying is an intermediate sludge treatment process that consists of evaporating the water in the sludge. The huber srt system is a unique and highly efficient process whereby sludge is dried in a greenhouse using incident solar radiation and artificially generated wind to evaporate water from the sludge. Solar energy is used to extract water from sewage sludge a simple and cheap process that not only reduces the sludge considerably in terms of volume but also saves truck mileage and c0 2 emissions.
