WebbSewage sludge is an inevitable by-product of biological wastewater treatment process and contains various toxic substances such as pathogens, heavy metals and organic contaminants, which may cause … Webb12 juli 2015 · A sludge drying bed is a common method utilized to dewater sludge via filtration and evaporation. Perforated pipes situated at the bottom of the bed are used to drain seepage water or filtrate. A reduction of about 35% or less in moisture content is expected after drying
WebbPrinciple of superheated steam drying. The material to be dried is introduced to the superheated steam atmosphere where it is heated up convectively after which its moisture evaporates. This heat transfer process is enhanced effectively, since superheated steam has a high heat capacity and thermal conductivity. WebbMoreover, the efficiency of the process will also depend on the drying technology, i.e. convective, conductive or solar, that can be more or less suited to the sludge properties. Even though some practical problems have been encountered in some industrial drying plants, their diffusion remains limited so that many operators still have to face …
WebbThe technology behind Drying Matter The input is wet sludge which typically contains 60-85% water. In the drying process the sludge is exposed to dry air which continuously circulate in a saturation cycle and drying cycle. This dry and slightly heated air is saturated by water vapor when in contact with the wet sludge. WebbFurthermore, dried sewage sludge is a much sought-after energy source with a positive CO 2 balance. Sewage sludge drying reduces transport and disposal costs and contributes therefore to sustainable resource preservation. Dried sewage sludge is an energy carrier of the future. Our experience for your benefit. HUBER sewage sludge drying systems.
