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.
Solar sludge drying system.
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 drying system is based on the greenhouse effect where sludge is spread into a greenhouse and mixed mechanically with a mixing device periodically.
Three processes are available.
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.
Also the automation degree of sewage sludge feeding and removal is variable.
Sludge can be dried in batches using a semi continuous process by means of a fully.
The sludge is transported.
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.
The basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation.
Contracting entity and operator was the disposer tirme sa who also operates a waste incineration plant on site where the dried sewage sludge is incinerated.
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.
Huber solar active dryer srt.
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.
Of solar sludge drying more economical more ecological.
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.
Height of the sludge should be around 30 cm to reach max.
The heat from the treated effluent is extracted by a heat.
