Studies of the physical-chemical aspects of deep trickling filters have been conducted at Oregon State University to investigate their use in terms of the kinetics of the physical-chemical and biochemical reactions that contribute to filter efficiency or which retard filter operations. The study has also involved development of methods for measurement of filter efficiency. Experimentation during the period of study covered by this project has included the major aspects of: Treatment of beet cannery wastes by deep filters; use of persulfate oxidizable carbon as a measure of organic pollution in water; criteria for evaluation of deep trickling filters; kinetics of deep biological contact beds; and, rate and mass transfer functions of biological treatment processes.
