A special sludge turning system performs both spreading and turning of the sludge as well as its transport from one side to the other.
Solar sludge drying system.
The sludge is transported.
The heat from the treated effluent is extracted by a heat.
The world s largest solar sludge drying plant was built by our partner the market leader thermo system in palma de mallorca.
Huber solar active dryer srt.
Three processes are available.
The combined sludge turning and transporting system is at the heart of the drying plant.
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.
Sludge can be dried in batches using a semi continuous process by means of a fully.
The basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation.
Height of the sludge should be around 30 cm to reach max.
Also the automation degree of sewage sludge feeding and removal is variable.
Of solar sludge drying more economical more ecological.
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.
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.
Solar drying system is based on the greenhouse effect where sludge is spread into a greenhouse and mixed mechanically with a mixing device periodically.
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.
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.
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.
