Solar Sludge Drying Facility

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 sludge drying facility.

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. If necessary they can also be switched on to dry partially unstabilized sludge. The plant is equipped with two air washers. Compared to conventional drying facilities about 2 million litres of fuel oil equivalent can be saved by the solar energy input per year.

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 combined sludge turning and transporting system is at the heart of the drying plant. The literature studies emphasize the benefits of solar drying used as gsd greenhouse solar dryer to reduce energy. Solar sludge drying excels in fulfilling key economic and environmental goals.

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. Sludge can be dried in batches using a semi continuous process by means of a fully. As the drying process is fully automatic only minimal staff effort is required. There are basically two common sludge drying methods thermal drying and solar drying.

Biwater has had a successful 52 years having achieved many firsts for the water industry across the globe. Three processes are available. While thermal drying requires high amount of energy solar drying cannot typically attain the 90 ds requirement. The sludge is transported.

In many cases biosolids are spread inside a greenhouse type structure that serves as a drying chamber. Acquisitions in the early years led to unparalleled growth. This facility will include a solar sludge drying greenhouse that will sustainably dry the effluent sludge produced as a biproduct from the wastewater treatment plant.
