Solar sludge drying.

Dewatered sludge and drying sludge are mixed and shaped into windrows by the soliamix windrow turner. Sludge can be dried in batches using a semi continuous process by means of a fully. The combined sludge turning and transporting system is at the heart of the drying plant. The sludge is transported.

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. The combination of the unique zizmann turning system and intelligent floor heating and aeration technology develops a natural solar sludge drying plant to a high end plant with evaporation results. Parkson says a consistent end product is always produced within a specific time frame with changing weather conditions having little effect on results. Windrow operation and regular addition of fresh sludge maximize bio drying and promote easy storage of sludge on a 6 months to 1 year cycle in the greenhouse.

The solar sludge drying systems can be erected on a variety of flat or inclined surfaces in a range of climates and can be adapted to retrofit existing drying beds. Solar radiation along with bio drying promotes a temperature rise within the. Also the automation degree of sewage sludge feeding and removal is variable. Solar sludge drying excels in fulfilling key economic and environmental goals.

Sludge can be dried in batches using a semi continuous process by means of a fully.

Solar sludge drying excels in fulfilling key economic and environmental goals.

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. 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 c02 emissions. Drying sludge for optimal recovery. Three processes are available.

Solar drying uses renewable energy and applicable in many parts of the. Solar sludge drying is an ideal method of reducing sludge volumes and disposal costs particularly in the australian climate.
