Odor Control System Engineering
BCE designs and implements a variety of odor control systems, including activated carbon adsorbers, wet chemical scrubbers, dry chemical scrubbers, and bio-filters. We understand the importance of installing the appropriate system to provide optimal performance, reliability, and value.
An odor control system is designed to scrub malodorous gases in the vapor phase or add chemical additives to the liquid phase to prevent noxious gases from forming. In wastewater treatment, odor control is critical. Microbes in sewage can produce hydrogen sulfide, infamous for its “rotten egg” smell, detectable at concentrations as low as 0.1 parts per billion.
Vapor Phase Odor Control Solutions
Activated Carbon Adsorbers
Air passes through a bed of porous granulated activated carbon. Odorous compounds adhere to the carbon granules and are neutralized. Spent carbon can be reactivated. Effective for hydrogen sulfide, VOCs, and other sulfur-based compounds.
Wet Chemical Scrubbers
Multi-stage packed towers provide intimate contact between scrubbing solution and malodorous air. Effective for hydrogen sulfide, ammonia, and various organic odors.
Dry Chemical Scrubbers
Utilize chemical media (typically KMnO4 or iron oxide) to convert sulfurous compounds into agreeable substances. Chemicals are consumed and require replacement, limiting operation to low-concentration sulfur air streams.
Bio-Filters
Microorganisms feed on organic material and oxidize sulfur. When operated at proper temperature and humidity, bio-filters efficiently remove sulfur-based compounds and mercaptans.
