Performance of three pilot-scale immobilized-cell biotrickling filters for removal of hydrogen sulfide from a contaminated air steam

The Performance of Compost Biofilter for Hydrogen Sulfide Removal from Contaminated Air

In order to evaluate the performance of biofilter for H2S removal from contaminated air, a 120×14 cm column biofilter was constructed using clear polyacrylic material in conjunction with H2S production and control systems. The column was divided into four stages using perforated plates. The column was packed with a mixture of mushroom compost and snail shell (4:1).&#10 The performance of biofil...

Removal of ammonia from contaminated air in a biotrickling filter - denitrifying bioreactor combination system.

The removal of gaseous ammonia in a system consisting of a biotrickling filter, a denitrification reactor and a polishing bioreactor for the trickling liquid was investigated. The system allowed sustained treatment of ammonia while preventing biological inhibition by accumulating nitrate and nitrite and avoiding generation of contaminated water. All bioreactors were packed with cattle bone comp...

Comparison on the removal of hydrogen sulfide in biotrickling filters inoculated with Thiobacillus thioparus and Acidithiobacillus thiooxidans

A high-performance adsorbent for hydrogen sulfide removal

Spatially well-distributed copper-zinc oxides supported on mesoporous silica (SBA-15 and commercial silica gel) showed high adsorption capacity for hydrogen sulfide (as high as 80 mgS/gsorbent) and stability during cyclic adsorption-regeneration process. 2014 Elsevier Inc. All rights reserved.
