The basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation.
Solar sludge drying system.
Solar drying system is based on the greenhouse effect where sludge is spread into a greenhouse and mixed mechanically with a mixing device periodically.
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.
Sludge drying system features solar greenhouse plant management at the rogue river or sewage treatment facility have used a new solar sludge drying system to reduce 120 000 gallons of 2 percent sludge from its facultative sludge lagoon to 10 cubic yards of 85 percent dry sludge.
Solar sludge drying excels in fulfilling key economic and environmental goals.
The combination of the unique turning system and intelligent heating and aeration technology develops a natural solar sludge drying plant to high end plant with evaporation results of more than 12 tonne water per square meter.
Also the automation degree of sewage sludge feeding and removal is variable.
Three processes are available.
The heat from the treated effluent is extracted by a heat.
Sludge can be dried in batches using a semi continuous process by means of a fully.
After dewatering the system is able to dry the sludge up to 90 dry solid to reach the energy values between 9 to 12 mj kg according to organic content and digestion.
Of solar sludge drying more economical more ecological.
Our options to meet specific needs a floor heating system to optimize drying cycles to ensure consistent performance throughout the year solia may be fitted with an additional source of energy.
The world s largest solar sludge drying plant was built by our partner the market leader thermo system in palma de mallorca.
A special sludge turning system performs both spreading and turning of the sludge as well as its transport from one side to the other.
Height of the sludge should be around 30 cm to reach max.
The combined sludge turning and transporting system is at the heart of the drying plant.
Huber solar active dryer srt.
The naturetech and i m solution offer the unique possibility to dry in combination with the solar power of global radiation and free heat sources.
