RESUMO
This study was designed to evaluate the performance of a cylindrical immobilized fixed Bed. Anaerobic digester in treating diluted municipal waste water. A series of three independent batch experiments was performed for a total operation time of 28 days. The system of anaerobic digestion showed stability conditions, with no noticeable scum or foaming problems. The anaerobic treatment of diluted municipal waste water is done using immobilized fixed bed anaerobic batch reactor. The source of waste generation is a mixed sludge collected from dock yard. The present study, thus initiated a need based experimental work on anaerobic digester incorporated with immobilized poly urethane foam system. The kinetic parameters are also estimated using experimental data. Empirical relations were developed for the characteristics like BOD, COD, SCOD, TDS and TSS using modeling equations.
