Webb30 mars 2024 · Sewage sludge is a useful raw material for the production of renewable energy due to its stable annual output. In this study, the enhancement of mesophilic anaerobic digestion of sewage sludge through heat pretreatment at 95 °C for 30 min was tested in an anaerobic moving bed biofilm reactor (hAMBBR). Webbclassified as a fire-resistant heat transfer fluid. Consequently, the use of protective devices may be required to minimize fire risk and users of Therminol 55 should check with their safety and risk management experts for specific instructions. 800 –225 600 550 –18 °F 427 –145 315 290 –28 °C heat transfer fluid THERMINOL ® 55
