Hydrodynamic study of Anaerobic Reactor for domestic wastewater treatment

The anaerobic reactor (ar) is a very important element in integrated algal ponding systems. the proper functioning of the ar directly influences the quality of treatment in the high rate algal pond. thus the control of hydrodynamics will both improve the design of such a structure and optimize its performance. this study aims to simulate the flow and distribution of temperature for different residence times (1.5 day,2 days,3 days) in the anaerobic reactor. the resolution of the flow equations and the energy equation is required. obviously the software fluent. this study is divided into two parts: • flow modeling • the temperature the results show that: • the mixture in the ar is not completely mixed • a temperature stratification in ar.
