Kinetics and Modeling of H2S Removal in a Novel Biofilter
Biofiltration has become a widely accepted technology for the removal of hydrogen sulfide (H2S) which is one of the major odor causing gases present in the air streams of municipal wastewater treatment facilities. In addition to odorous nature, H2S is toxic and corrosive. In this study, a biofilter which uses a novel media was employed in a pumping station which is closely located at the Univer...
متن کاملRemoval of Hydrogen Sulfide from Septic Tank by Vermicomposting Bio Filter
Background & Aims of the Study: Hydrogen sulfide (H2S) is a colorless and highly toxic, easily dissolved in water, flammable and explosive gas. Hydrogen sulfide gas is the main cause of odor emissions from municipal sewage plants. One method for removal of hydrogen sulfide gas is the use of biological systems, biofilter. The aim of this study was to survey removal hydrogen sulfide provide in se...
متن کاملH2S removal and bacterial structure along a full-scale biofilter bed packed with polyurethane foam in a landfill site.
Hydrogen sulfide accumulated under a cover film in a landfill site was treated for 7 months by a full-scale biofilter packed with polyurethane foam cubes. Sampling ports were set along the biofilter bed to investigate H2S removal and microbial characteristics in the biofilter. The H2S was removed effectively by the biofilter, and over 90% removal efficiency was achieved in steady state. Average...
متن کاملTwo-stage biofilter for effective NH3 removal from waste gases containing high concentrations of H2S.
A high H2S concentration inhibits nitrification when H2S and NH3 are simultaneously treated in a single biofilter. To improve NH3 removal from waste gases containing concentrated H2S, a two-stage biofilter was designed to solve the problem. In this study, the first biofilter, inoculated with Thiobacillus thioparus, was intended mainly to remove H2S and to reduce the effect of H2S concentration ...
متن کاملEffect of weathering on mobilization of biochar particles and bacterial removal in a stormwater biofilter.
To improve bacterial removal, a traditional stormwater biofilter can be augmented with biochar, but it is unknown whether bacterial removal remains consistent as the biochar weathers during intermittent exposure to stormwater under dry-wet and freeze-thaw cycles. To examine the effect of weathering on bacterial removal capacity of biochar, we subjected biochar-augmented sand filters (or simplif...
