Solar Sludge Drying

Dewatered sludge and drying sludge are mixed and shaped into windrows by the soliamix windrow turner.

Solar sludge drying.

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. 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 drying is becoming a popular option to replace mechanical thermal dryers mathioudakis et al 2013. The sludge is transported.

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. Solar sludge drying excels in fulfilling key economic and environmental goals. Solar sludge drying is an ideal method of reducing sludge volumes and disposal costs particularly in the australian climate. Also the automation degree of sewage sludge feeding and removal is variable.

Solar radiation along with bio drying promotes a temperature rise within the. Three processes are available. 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. The first one is the sticky phase of the sludge and the second one is the risk of ignition and burning of sludge during drying process flaga 2007 malhotra 1989.

Parkson says a consistent end product is always produced within a specific time frame with changing weather conditions having little effect on results. The combined sludge turning and transporting system is at the heart of the drying plant. Solar drying uses renewable energy and applicable in many parts of the.

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 limits of mechanical sludge drying sometimes create the need for thermal drying by water evaporation. Suez has developed a number of sludge drying processes that allow the sludge to be recovered for a multitude of uses as fertilisers co products for composting or as fuel for incineration plants.

Drying sludge for optimal recovery. 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.
