| Summary: | A pilot study was
performed at the Fox River Fiber recovered paper
processing company in DePere, Wisconsin, to
determine the extent to which injection of
oxygen and ozone could reduce the high chemical
oxygen demand, COD, in the effluent and the
effectiveness of the ozone/oxygen stream in
suppressing production of hydrogen sulfide gas
in downstream sewage lines. Adaptive Ozone
Solutions, LLC, supplied the oxygen/ozone
generation and injection system. Samples were
analyzed both before and after oxygen/ozone
injection. Hydrogen sulfide gas was continuously
monitored at sewer stations downstream of Fox
River Fiber. Results showed that with a very
short contact time, effluent COD was reduced by
over 15%. A simple kinetic model predicts
that a contact time of fewer than 30 minutes
could reduce COD by as much as 60%. In
addition, downstream hydrogen sulfide gas
production in the sewage mains was also better
controlled, such that costly Bioxide
applications could be reduced. |
