Effect of Microwave-coupled Fe0/H2O2 on Excess Sludge Dewaterability
Taiyuan Ligong Daxue xuebao, 2021 The effects of initial pH, microwave power, reaction time, H2O2 dosage, and Fe0 dosage in microwave-coupled Fe0/H2O2 (MW-Fe0/H2O2) Fenton-like process on sludge dewaterability were systematically investigated by the specific resistance to filtration (SRF)

Limits of sludge dewaterability
Water Science and Technology, 1997 Water in sludge appears to be of four kinds; free water which freezes at normal freezing temperatures; interstitial water, which freezes at lower temperature due to high dissolved solids concentrations; vicinal water which is associated with solid surfaces and freezes only at very low temperatures; and water of hydration, which does not enter the ice ...

Aerobic Granular Sludge: Perspectives for Excess Sludge Management and Resource Recovery
Chemie Ingenieur Technik, Volume 95, Issue 12, Page 1881-1896, Dezember 2023., 2023 Abstract Aerobic granular sludge (AGS) technology is gaining increasing interest globally. However, several aspects are still challenging its installation, as the integration into existing municipal wastewater treatment plants. The operation of AGS units in continuous flow mode could facilitate that integration; yet has only been experienced at lab and

Evaluation of pre-magnetization on the dewaterability of waste activated sludge treated by ozonation
Water Cycle, 2023 The dewaterability of waste activated sludge (WAS) plays the key role in sludge dewatering in wastewater treatment plants. The magnetic field as a source of clean energy has been reported to be able to cause changes in sludge properties and to enhance ...

Journal of Chemical Technology &Biotechnology, Volume 98, Issue 1, Page 230-237, January 2023., 2023 Abstract BACKGROUND Food waste (FW) and waste activated sludge (WAS) are complementary substrates that improve H2 production by dark fermentation. However, there is little experience in the process performance in the long‐term operation of reactors co‐processing FW–WAS.
