Operation performance of up-flow anaerobic sludge blanket (UASB) bioreactor for biohydrogen production by self-granulated sludge using pre-treated palm oil mill effluent (POME) as carbon source

Renewable Energy, 2019
Palm oil mill effluent (POME), an agro-industrial wastewater with high solids content, was subject to hydrolysis by 1% (w/v) nitric acid in order to increase its solubility and the fermentable sugar content from its cellulosic component. POME hydrolysate

High strength sewage treatment in a UASB reactor and an integrated UASB-digester system

Bioresource Technology, 2008
The treatment of high strength sewage was investigated in a one-stage upflow anaerobic sludge blanket (UASB) reactor and a UASB-digester system. The one-stage UASB reactor was operated in Palestine at a hydraulic retention time (HRT) of 10h and at ambient air temperature for a period of more than a year in order to asses the system response to the ...

Technical review on the UASB process

International Journal of Environmental Studies, 1991
This paper presents a comprehensive review of the UASB wastewater treatment process. Factors affecting granulation of the anaerobic sludge, start‐up of the process and operation of UASB reactor are analyzed. Criteria about design and construction of the UASB reactor are described, and studies on mathematical modeling of fluid flow pattern, sludge ...

A two-phase anaerobic digestion (UASB-UASB) process: design criteria and optimal system loading capacity

Canadian Journal of Civil Engineering, 1995
This research evaluated the effectiveness and feasibility of two-phase (separation acid and methanogenic phases) anaerobic digestion of simulated sewage sludge using a UASB-UASB (upflow anaerobic sludge blanket) process. Predictive models of chemical oxygen demand (COD) (soluble) removal efficiency and CH4 gas production during loading maximization ...

Preservation characteristics of UASB Sludges

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1997
Abstract Anaerobic treatment has become popular as an effective means for the treatment of high strength wastewaters, however, quantitative research on the preservation characteristics of anaerobic sludges is necessary when an anaerobic reactor is considered for use in industries operating intermittently.
