Bahgat, T.M.S.M. (author), Wilfert, P.K. (author), Korving, Leon (author), van Loosdrecht, Mark C.M. (author)The study evaluated the combined phosphorus, nitrogen, methane, and extracellular polymeric substances (EPS) recovery from aerobic granular sludge (AGS) wastewater treatment plants. About 30% of sludge organics are recovered as EPS and 25–30% as methane (≈260 ml methane/g VS) by integrating alkaline anaerobic digestion (AD). It was shown that...journal article 2023

van Loosdrecht, Mark C.M. (author), Hao, Xiaodi (author), Wu, Yuanyuan (author)摘要： 好氧颗粒污泥技术具有占地面积小、能耗低、剩余污泥量少、抗冲击性强等优点，是<br/>一种可持续的污水处理技术。以北京某污水处理厂实际生活污水作为基质，在中试规模（有效容积<br/>为2.5 m3）反应器中进行好氧颗粒污泥培养，研究了颗粒污泥在低温条件下的稳定性。中试自夏季<br/>开始运行到次年春季结束，共计运行260 d。结果表明，采用我国实际低碳源市政污水可以培养出好<br/>氧颗粒污泥，污泥颗粒化程度可达94%，SVI5/SVI30为1.1 ~ 1.3。冬季低温会造成颗粒污泥的枝状结<br/>构增多、丝状菌生长，进而引起颗粒化比例略有下降，为80%~91%，污泥平均粒径降低，SVI5/SVI30升<br/>高至1.5 ~ 1.8。在冬季低温条件下，通过优化调控进水流量...journal article 2022

Chaudhari, Bhavesh (author), Panda, Biranchi (author), Šavija, B. (author), Chandra Paul, Suvash (author)Microbiologically induced concrete corrosion (in wastewater pipes) occurs mainly because of the diffusion of aggressive solutions and in situ production of sulfuric acid by microorganisms. The prevention of concrete biocorrosion usually requires modification of the mix design or the application of corrosion-resistant coatings, which requires a...journal article 2022

(author)Anammox bacteria enable efficient removal of nitrogen from sewage in processes involving partial nitritation and anammox (PN/A) or nitrification, partial denitrification, and anammox (N-PdN/A). In mild climates, anammox bacteria must be adapted to ≤15 °C, typically by gradual temperature decrease; however, this takes months or years. To...journal article 2022

Gu, Chunping (author), Ji, Yongjie (author), Yang, Yang (author), Liu, Jintao (author), Ni, Tongyuan (author)Sewage sludge ash (SSA) is the combustion residue of the sewage sludge obtained from wastewater treatment plants. In China, SSA normally contains high content of SO3, which may cause detrimental effect on the volume stability of cement-based materials. This study investigated the effect of sulfate-rich SSA (SR-SSA) on the volume deformation and...conference paper 2021

Avadhani, M. (author), van Rooyen, Roland (author), Infante Ferreira, C.A. (author)Buildings consume 40% of the total global energy and contribute to over 30% of all CO2 emissions. Space heating forms a significant part of energy consumption in buildings. A possible solution is to recover waste heat from sewage and to upgrade its exergy using a heat pump. Polymers reduce cost and energy required for manufacturing the heat...conference paper 2021

Understanding the impact of a pressure sewer on municipal wastewater: a pre-treatment for AGS plantsMerola, Chiara (author)The performance of AGS reactors treating municipal wastewater can be optimised by converting influent particulate matter into readily available substrate. This can be done via anaerobic hydrolysis and fermentation of the influent. Anaerobic processes taking place in pressure sewers are not fully understood but show the potential to act as a pre...master thesis 2020
