Sludge drying properties. Sludges of different origins and characteristics exhibit different behaviours when drying. These are most readily observed by correlating the mass water flux – the mass of water evaporated per unit surface area of solids per unit time (kg m-2 s-1) – against the moisture content of the sludge.This correlation normally reveals the three …
For dewatering the sludge of every nature produced by treatment plants, TEKNOFANGHI proposes TEKNOBAG-DRAIMAD ®. The heart of the system is the original draining bag TEKNOBAG-DRAIMAD ®, which permits to reach 15-30% dry solids content after only a few hours and 50-80% of dry solids after certain storage period. The right management …
Solar-Regenerative Dryers utilize solar energy as well as low-temperature heat for sludge drying to a solids content of usually above 65% DS. We preferably use additional waste heat or wastewater heat from renewable sources to speed-up the drying process. This type of dryer is particularly suited for small to medium-sized wastewater treatment ...
