The sludge dewatering system can deliver sludge without intermediate storage – fully automated, unmanned operation of the entire sludge treatment system. Dry sludge removal can be adjusted depending on the operation on site: The dry granulate can be stored in depressions accessible for a wheel loader to empty these into trucks or dumpers.

This treatment aims to reduce the sludge volume through dehydration and drying processes capable of reducing its initial volume by up to 85% (Mathioudakis et al., 2009), promoting sludge sanitization and reducing handling and transport costs.
GSD supported with solar panels are cost-effective compared to thermal dryers. GSD with solar panels are suggested for small and medium sized WWTPs. Sludge production
El Hammoudani and Dimane (2021) have monitored the occurrence of PAHs during sludge treatment including thickening, mechanical dewatering, and chemical stabilization (lime addition) in an activated sludge-based WWTP. The studied PAHs ranged between the quantification limit and 0.25 mg/kg in thickened sludge, while a maximum of 0.10 mg/kg has

Solar drying of sludge uses the energy of the sun as a thermal energy source. This provides a very ecological, environmentally friendly and energy-efficient process for the treatment of sludge from wastewater treatment plants or water purification plants. The basic principle of the process is that the sludge is dried in a greenhouse structure
GSD supported with solar panels are cost-effective compared to thermal dryers. GSD with solar panels are suggested for small and medium sized WWTPs. Sludge production rates and initial dry solids content affect area and costs.

Footnote: The Solar Farm at Siu Ho Wan Sewage Treatment Works was commissioned in 2016. At that time, it consisted of around 4,200 solar panels at Area A, B and C, with a generation capacity of 1,100 kilowatts. Later, the Solar Farm was expanded to other plant facilities. At present, around 5,000 solar panels are installed at the Solar Farm and

HUBER supplies the technology for solar sewage sludge drying for the wastewater treatment plant in Pachacútec. The plant, located more than 10,000 kilometres from HUBER''s Berching site, is already the second project in Peru using the innovative drying technology with the HUBER Sludge Turner SOLSTICE® and solar energy.
HUBER Solar Active Dryer SRT: The basic principle of the system is drying of sewage sludge in a glasshouse using the incident solar radiation. A special sludge turning system performs both spreading and turning of the sludge as
Solar drying provides the lowest energy demand of all dryers, as low as 50 kWh/t. Although heating is provided at zero or minimal cost, energy is demanded by both the mechanical agitation of the sludge solids and deodorisation of the exhaust air.
Abstract: The biggest problem in wastewater treatment is what can be done with the sewage sludge. Generally, there are few possibilities to manage it such as landfill, incineration or use it as a
Drying with the natural power of the sun. While conventional sludge dryers have a very high energy requirement – over 800 kWh per tonne of water removal – the WendeWolf® system only requires 20-30 kWh of electricity.
As it is difficult to exhaustively assess the concentration of pathogenic microorganisms in SS after the solar drying process, total coliform and fecal coliform are mostly studied in the literature as indicators of contamination in sludge and among the criteria to assess the sanitizing effect of sludge treatment.
Sludge disposal is a high-cost activity, and drying the sludge reduces its mass and volume, resulting in savings in storage, handling and transportation. The discoveries regarding the use of solar energy in agricultural studies provided valuable information for using in sewage sludge drying.
Modeling techniques can predict the behavior of the solar drying system and, thus, save time and money in experimental steps. CFD modeling of the sludge drying system is usually done by adopting specific boundary conditions and solving the Navier Stokes equations for air and sludge.
The use of free solar energy is practical and beneficial for greenhouse sludge drying processes. It provides dried sludge with minimal energy consumption and lower construction costs than other alternatives. Spreading the sludge in thick layers is the most common way to prepare the sludge for drying.
Excessive sludge from sewage treatment results from bacterial growth, the formation of inert materials in wastewater, and the buildup of endogenous residue. This article looks at the development of an innovative sewage sludge drying method using a modified solar greenhouse. The paper was published in Clean Technologies.
They take the form of large greenhouses into which the sludge is fed either continuously or in batches. Solar drying provides the lowest energy demand of all dryers, as low as 50 kWh/t. Although heating is provided at zero or minimal cost, energy is demanded by both the mechanical agitation of the sludge solids and deodorisation of the exhaust air.
