A literature study was conducted to compare the feasibility of biofilters and biotrickling filters
for the treatment of complex odorous waste air containing hydrogen sulfide (H2S), organic …

Bioprocesses have been developed as relatively recent alternatives to conventional, non‐
biological technologies, for waste gas treatment and air pollution control in general. This …

The production of biogas from sulfate-rich materials under anaerobic digestion results in the
formation of hydrogen sulfide (H2S). The recommended level of H2S in the produced biogas …

In the work described here, a biotrickling filter with Thiobacillus thioparus (ATCC 23645)
immobilized on polyurethane foam is proposed for the removal of hydrogen sulfide …

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. Title
I of the Clean Air Amendment (CAA) defines a VOC as any compound containing carbon …

A biofilter packed with granular activated carbon (GAC) was applied to eliminate volatile-
sulfur compounds (VSC) emitted from solid–liquid separation tank in swine wastewater …

The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter
(BTF) packed with plastic Pall rings operating with counter‐current flows of the air and liquid …

Increasing urban growth and lifestyle expectations have led to an increase in public
complaints against odours from sewer infrastructure. Gas phase odour abatement in sewer …

Using hybrid packing materials in biofiltration systems takes advantage of both the inorganic
and organic properties offered by the medium including structural stability and a source of …

In this study, the effects of pH, CO2, and flow pattern on the performance of a biotrickling
filter (BTF) packed with plastic Pall rings and treating a H2S‐polluted waste gas were …
