Abstract
Official abstract text for this publication.
A system for removing undesirable compounds from contaminated air includes a biofilter having an alkaline material introduction system and a fuzzy-logic based controller. A contaminant, such as hydrogen sulfide, is removed from contaminated air by passing the contaminated air through the biofilter.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of removing hydrogen sulfide from contaminated air, the method comprising: flowing the contaminated air through a biotrickling filter including a media bed and a population of hydrogen sulfide oxidizing bacteria disposed on media in the media bed, the population of bacteria oxidizing hydrogen sulfide in the contaminated air into sulfuric acid; introducing water from a source of water into the biotrickling filter; measuring a pH of water having p…
