It has been especially useful for odors, particularly from composting and other waste management facilities, but also is being employed for a variety of industrial emissions.

Ammonia control applications have been somewhat problematic, yet may increase dramatically in response to newly implemented Clean Air Act requirements.

Ethylene is of concern in some intense greenhouse growing conditions and for fresh food storage. Methane is important in mines and as a fugitive emission from landfills, with substantial greenhouse gas implications.

The broad objective of this work is to systematically study and further develop this biological air treatment system.

In biofiltration, the contaminated gas stream is passed through a moist solid support material that contains nutrients and enriched microbial communities capable of utilizing the contaminants, resulting in their treatment.

Work began with two model compounds, ammonia and ethylene, then progressed to treatment of other compounds and defined mixtures. Ammonia was chosen because of its importance in NASA's advanced life support systems and other enclosed environments, as well as in some waste treatment, agricultural, and industrial systems, and because the products of its transformation accumulate.

Studies on the effectiveness of rinsing of biofilters for removal of inorganic nitrogen compounds also are completed. Methane treatment initially was not as successful. Mixtures of ammonia and methane were treated to test the ability of biofilters to remove methane and see the effect of carbon to nitrogen ratio on efficiency.

Aminophosphonic acids are an important group of medicinal compounds, and their synthesis has been a focus of considerable attention in synthetic organic chemistry as well as medicinal chemistry. Although the phosphonic and carboxylic acid groups differ considerably with respect to shape, size, and. Molecular structure and its determination by modern physical methods, correlation between structure and reactivity and the theoretical basis for these relationships, classification of reaction types exhibited by organic molecules using as examples molecules of biological importance.

Because of the interaction between these two compounds on a biochemical level both oxidized by mono-oxygenasesethanol also was treated as another simpler model organic compound.

In addition to the problems posed by its very low water solubility, methane treatment was slowed by nitrogen limitations after several weeks of operation. Co-treatment of ethanol with methane did not improve methane removal under the conditions tested. A dynamic mathematical simulation model was developed to incorporate this information.

It examines inlet contaminant concentration, gas residence time, compound hydrophobicity, mass transfer rates, biofilter surface area, biomass growth, and nitrogen limitations. Not relevant to this project. The target audiences for this work are pollution control and treatment professionals.

These groups are reached by presentations at industry and professional meetings, and through publications.

The audience also includes upper level students who intend to become these professionals. Impacts Biofiltration is a cost effective means of air pollutant emission control.

The ongoing work helps extend the range of contaminants and situations for which biofiltration can be used.

Also, through better understanding of the biological and physical-chemical processes involved, increased efficiency can be achieved.

The dynamic mathematical model developed is expected to be of assistance in efficient design and operation of biofilters. The work on methane specifically may help to reduce emissions of this very important greenhouse gas, and may also serve as a model for treatment of other poorly-water soluble compounds.

The results of this project to date have been incorporated in the class Biological Waste Treatment.This organic chemistry course note focuses on the methods used to identify the structure of organic molecules, advanced principles of organic stereochemistry, organic reaction mechanisms, and methods used for the synthesis of organic compounds.
