Sample text

With simple dissolved matter, it is taken into the cell and oxidized, but with more complex inorganics, enzymes are secreted extracellularly to hydrolyze the proteins and fats into a soluble form which can then be taken into the cell and oxidized. Hence the more complex matter takes longer to process. Some organic compounds are "refractory," they cannot be oxidized while others are toxic to the bacteria at high concentrations. The purpose of biodegradation is to convert the waste into the end products and material that will settle and can be removed as sediment.

The gas to be treated is pumped through the media and escapes through holes in the pipe wall. It rises through the media bed which is usually 3-10 ft. deep. Pollutants captured on the biofilter can be removed by filtration, physical and chemical absorption, chemical oxidation, and structural treatment. The technique is not a new one, filters have been used for many years to remove odors from agricultural, food, and wastewater processing operations, and emissions from paper and chemical manufacturing plants.

This will be discussed prior to the laboratory work. Included in this section and not in the pilot studiedin-situ section is work on 1, 1 ,1-trichloroethane, which is an insitu study. It is placed here because it is an example of anaerobic degradation. The work with fungi has so far been ignored. Although there has been a great deal of information about fungal degradation in the past years, the majority of published works dealt with bacteria. INTRODUCTION Hazardous waste does not consist of one chemical or attribute; the definition of it is a wide one.
