Guo, H. (author), Oosterkamp, M.J. (author), Tonin, F. (author), Hendriks, Alexander (author), Nair, Revathy (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Hydrolysis is considered to be the rate-limiting step in anaerobic digestion of waste activated sludge (WAS). In this study, an innovative 4 stages cascade anaerobic digestion system was researched to (1) comprehensively clarify whether cascading configuration enhances WAS hydrolysis, and to (2) better understand the governing hydrolysis...journal article 2021

Gonzales, A. (author), Guo, H. (author), Ortega-Ibáñez, Oscar (author), Petri, Coert (author), van Lier, J.B. (author), de Kreuk, M.K. (author), Hendriks, Alexander (author)Sludge pre-treatments are emerging as part of the disposal process of solid by-products of wastewater purification. One of their benefits is the increase in methane production rate and/or yield, along with higher loading capacities of existing digesters. In this study, we report the performance of a pilot-scale compartmentalized digester (volume...journal article 2020

Kassab, Ghada (author), Kather, Dima (author), Odeh, Fadwa (author), Shatanawi, Khaldoun (author), Halalsheh, Maha (author), Arafah, Mazen (author), van Lier, J.B. (author)As a potential approach for enhanced energy generation fromanaerobic digestion, iron-based conductive nanoparticles have been proposed to enhance the methane production yield and rate. In this study, the impact of two different types of iron nanoparticles, namely the nano-zero-valent-iron particles (NZVIs) and magnetite (Fe<sub>3</sub>O<sub>4...journal article 2020

Wei, P. (author), Tan, Qiuman (author), Uijttewaal, W.S.J. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)For a proper operational performance assessment of excess sewage sludge digesters in practice, a better understanding of waste activated sludge (WAS) rheological behaviour is important, especially regarding the low-shear and poor mixing zones in anaerobic digesters. The potential rheological instability of WAS with different total solids (TS)...journal article 2018

Gonzales, A. (author), Hendriks, A.T.W.M. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Pre-treatments for waste activated sludge (WAS) are, in most cases, an attempt to increase the biodegradation and/or improve hydrolysis rate of WAS after anaerobic digestion. This review presents an extensive analysis of WAS pre-treatments effectiveness focusing on increasing the biodegradability. In the first part of the review, WAS is...journal article 2018
