Cascade degradation of organic matters in brewery wastewater using a continuous stirred microbial electrochemical reactor and analysis of microbial communities
Wang, Haiman; Qu, Youpeng; Li, Da; Ambuchi, John Justo; He, Weihua; Zhou, Xiangtong; Liu, Jia; Feng, Yujie (Scientific Reports, 2016)A continuous stirred microbial electrochemical reactor (CSMER), comprising of a complete mixing zone (CMZ) and microbial electrochemical zone (MEZ), was used for brewery wastewater treatment. The system realized 75.4±5.7% ... -
A combined microbial desalination cell and electrodialysis system for copper-containing wastewater treatment and high-salinity-water desalination
Donga, Yue; Liua, Junfeng; Sui, Mingrui; Ambuchi, John Justo; Qub, Youpeng; Wanga, Haiman; Fenga, Yujie (Journal of Hazardous Materials, 2017)A new concept for heavy metal removal by forming hydroxide precipitation using alkalinity produced by microbial desalination cell (MDC) was proposed. Four five-chamber MDCs were hydraulically connected to concurrently ... -
Determination of Heavy Metal Levels in Surface Waters and Sediments of River Riana, Kisii County, Kenya
Mongare, Thomas Momanyi; Ambuchi, John Justo; Ngodhe, Steve Omari; Nyamai, Daniel; Ongachi, Francis Olal; Wanjara, Amos Otieno (2023-10)In this paper, some trace metals were seasonally determined for six months between January -June 2021 (to cover both the wet and dry seasons) in surface water and sediments from River Riana in Kisii County. The river ... -
Hematite and multi-walled carbon nanotubes stimulate a faster syntrophic pathway during methanogenic beet sugar industrial wastewater degradation
Ambuchi, John Justo; Zhang, Zhaohan; Dong, Yue; Huang, Linlin; Feng, Yujie (2017-09-22)The quest to understand and subsequently improve the role played by bacteria and archaea in the degradation of organic matter both in natural and engineered anaerobic ecosystems has intensified the utilization of ... -
Integrated expanded granular sludge bed and sequential batch reactor treating beet sugar industrial wastewater and recovering bioenergy
Ambuchi, John Justo; Junfeng, Liu; Lili, Shan; Haiman, Wang; Lorivi, Moirana Ruth; Mohammed, Mohammed O. A; Xiangtong, Zhou; Yujie, Feng (2016-07-21)The exponential rise in energy demand vis-à-vis depletion of mineral oil resources has accelerated recovery of bioenergy from organic waste. In this study, a laboratory- scale anaerobic (An)/aerobic (Ar) system ... -
