Dissolved methane oxidation and competition for oxygen in down-flow hanging sponge reactor for post-treatment of anaerobic wastewater treatment.
Post-treatment of anaerobic wastewater was undertaken to biologically oxidize dissolved methane, with the aim of preventing methane emission. The performance of dissolved methane oxidation and competition for oxygen among methane, ammonium, organic matter, and sulfide oxidizing bacteria were investigated using a lab-scale closed-type down-flow hanging sponge (DHS) reactor. Under the oxygen abun...
متن کاملHYDRAULIC BEHAVIOR IN THE DOWNFLOW HANGING SPONGE BIOREACTOR Karakteristik Hidraulik pada Bioreactor Downflow Hanging Sponge
Performance efficiency in a Downflow Hanging Sponge (DHS) bioreactor is associated with the amount of time that a wastewater remains in the bioreactor. The bioreactor is considered as a plug flow reactor and its hydraulic residence time (HRT) depends on the void volume of packing material and the flow rate. In this study, hydraulic behavior of DHS bioreactor was investigated by using tracer met...
متن کاملassesment of kinetic parameters for thermophilic anaerobic contact reactor treating food-processing wastewater
a thermophilic anaerobic contact reactor for the treatment of potato-processing wastewaterswas designed as a continuous-flow, completely-mixed homogeneous system. the reactor was operated at ten different organic loading rates ranging from 0.84 g cod/l·d to 7.00 g cod/l·d for a duration of approximately 250 days. the fundamental way to maintain optimum operating conditions of anaerobic digestio...

متن کاملrubber and methane recovery from deproteinized natural rubber wastewater by coagulation pre-treatment and anaerobic treatment
a newly developed natural rubber deproteinization process produces deproteinized natural rubber (dpnr) wastewater as an intermediate product containing a high concentration of sodium dodecyl sulfate (sds) and rubber. in this study, a novel process to recover the residual rubber and energy as methane from dpnr wastewater was developed. as a pretreatment, sds and residual rubber in dpnr wastewate...
