Manufacturing Process and Optimization

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 distribution and biological conversion of substrate in the UASB reactor are reviewed. Finally, applications of the process to the treatment of various types of wastewater are summarized. Key words: UASBanaerobicsludgegranulationwastewaterreview
