The main objective of this study was to achieve the continuous biorecovery and bioreduction Pb(II) using an industrially obtained consortia as a biocatalyst. An upflow anaerobic sludge blanket reactor used in treatment process. bioremediation technique that applied made use yeast extract microbial substrate Pb(NO3)2 source Pb(II). UASB exhibited removal efficiencies between 90 100% for inlet Pb...

The performance of an EGSB (expanded granular sludge bed) reactor type using flocculent sludge was evaluated for the post-treatment of effluent from UASB reactor treating domestic sewage. A pilot-scale 157.5-L EGSB reactor was monitored during a 331-day period. The original concept of the EGSB reactor was based on the granular sludge use and by applying high upflow liquid velocities (vup). Howe...

This work studied the influence of effluent recirculation upon kinetics anaerobic degradation dairy wastewater in intermittent UASB (Upflow Anaerobic Sludge Bed) reactors. Several laboratory-scale tests were performed with different organic loads a reactor inoculated flocculent sludge from an industrial treatment plant. The data obtained used for determination specific substrate removal rates a...

The concept of carbon credit arose out of increasing awareness of the need to reduce emissions of greenhouse gases to combat global warming which was formalized in the Kyoto protocol. In addition to contribution to sustainable development with energy recovery in the form of methane, carbon credits can be claimed by application of advanced anaerobic processes in wastewater treatment for reducing...

Upflow anaerobic sludge blanket (UASB) reactor has served as an effective process to treat industrial wastewater such as purified terephthalic acid (PTA) wastewater. For optimal UASB performance, balanced ecological interactions between syntrophs, methanogens, and fermenters are critical. However, much of the interactions remain unclear because UASB have been studied at a "macro"-level perspect...
