Rheological behavior of sewage sludge with high solid content

WebbResearch in manufacturing often develops incrementally, typically by extending known methods of analysis and applying them to known processes or by extending existing processes or systems. WebbThermal hydrolysis process is widely used as a pretreatment for sludge AD, which can change rheological properties and dehydration of sludge irreversibly. The experiment was designed to evaluate the effect of high-temperature thermal hydrolysis (120, 130, 145, 160 and 170°C) for 60 min on sludge rheological properties, as well as its dewaterability. WebbNovel sludge types are also emerging from new processes, such as thermal hydrolysis, and their rheological profile cannot be predicted using existing data. To meet these multiple challenges, SLOT 2.0 – short for System LOsses Tool - has been developed to help utilities know their sludge better. culver\u0027s washington ave sheboygan
