Low-Cost Biological Odor Treatment Using an Adsorption/Desorption Concentrator Unit for Reducing Sulfur Emissions in Nebraska

Client

University of Nebraska, USA

Project Description

This application proposes the design and testing of an economical odor treatment system that will contribute to lower ambient H₂S and other gas phase pollutants within the state. The novelty of this project is in the concentrator, which has the potential for new patents and broad implementation. Using adsorption/desorption processes, concentrated H₂S will result in a smaller reactor volume for a reduced direct and operational costs in a bio-trickling filter (BTF). The project is divided into a series of laboratory experiments to develop the concentrator and field demonstrations at a food composting facility to test efficacy. The laboratory experiments will examine the cyclic adsorption and desorption rates of H₂S by evaluating raw zeolite and activated carbon manufactured from bituminous and coconut sources in granular, powder, and fibrous forms.
