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

Guo, H. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Full-scale aerobic granular sludge technology under the trade name Nereda® has been implemented for municipal, as well as industrial wastewater treatment. Owing to the operational reactor procedures, two types of waste aerobic granular sludge can be clearly distinguished: 1) aerobic granular sludge selection discharge (AGS-SD) and 2) aerobic...journal article 2020

Guo, H. (author), Felz, S. (author), Lin, Y. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Aerobic granular sludge (AGS) technology is an alternative to conventional activated sludge to reduce the process footprint and energy consumption. Strategies for the efficient management of its produced biomass, that is grown in a granular morphology as well, need further development. Anaerobic digestion (AD) is commonly applied in waste...journal article 2020

Kooijman, G. (author), Lopes, Wilton (author), Zhou, Z. (author), Guo, H. (author), de Kreuk, M.K. (author), Spanjers, H. (author), van Lier, J.B. (author)In this work, we investigated the effects of flocculation aid (FA) addition to an anaerobic dynamic membrane bioreactor (AnDMBR) (7 L, 35°C) treating waste-activated sludge (WAS). The experiment consisted of three distinct periods. In period 1 (day 1–86), the reactor was operated as a conventional anaerobic digester with a solids retention...journal article 2017
