Solar Sludge Drying Facility

The plant is equipped with two air washers.

Solar sludge drying facility. In many cases biosolids are spread inside a greenhouse type structure that serves as a drying chamber. 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. The combined sludge turning and transporting system is at the heart of the drying plant. Solar sludge drying excels in fulfilling key economic and environmental goals.

Sludge can be dried in batches using a semi continuous process by means of a fully. Also the automation degree of sewage sludge feeding and removal is variable. 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. Sunlight enters the drying chamber and heats the air inside.

Acquisitions in the early years led to unparalleled growth. While thermal drying requires high amount of energy solar drying cannot typically attain the 90 ds requirement. There are basically two common sludge drying methods thermal drying and solar drying. As the drying process is fully automatic only minimal staff effort is required.

The basic principle of operation of a solar drying system is to evaporate water from the sludge with 95 of its drying energy coming from the sun s solar energy. 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. 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. Biwater has had a successful 52 years having achieved many firsts for the water industry across the globe.

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. Three processes are available. The literature studies emphasize the benefits of solar drying used as gsd greenhouse solar dryer to reduce energy.
