In wastewater treatment, sludge drying reduces the weight and volume of the final waste product for easier, safer, and more cost-effective storage, transportation, and disposal.www.elodeusa.com/glossary/sludge-dryingwhat is sludge drying? Sludge drying refers to the process of removing most of the water content from sludge through actions such as percolation or evaporation.The sludge drying methods are mainly natural evaporation and mechanical dehydration, both of which aim to further reduce the moisture content of the sludge.www.environmental-expert.com/articles/what-is-slu…In sludge drying the moisture from sludge is removed as water vapour by heating, rather than being removed as a liquid via mechanical means such as in thickening or dewatering. The sludge is normally dried to solid concentrations above 65% to produce pellets or, at the highest solids concentrations of 90% or more, a powder.www.sludgeprocessing.com/process-and-operation…Sludge drying refers to processes where moisture is removed from sludge as water vapour. This is to be distinguished from processes where sludge is dried by purely mechanical means, such as thickening or dewatering where moisture is removed as a liquid.www.sludgeprocessing.com/sludge-drying/introduc…
