RESULTS AND DISCUSSION
The aeration chamber of the full scale plant was seeded with 1,000 gallons
of 4,500 mg/l returned activated sludge from a large municipal treatment
plant at the project initiation. Water meters were installed for continuous
recording of water consumption during fish processing. Wastewater from fish
processing was pumped to the treatment facility after fine screening, and
sanitary wastes were conveyed to a septic tank for treatment. Based on
pumping duration and rate, the flow entering the extended aeration system
was computed. A weir box was installed at the aerobic pond to record the
flow rate of effluent from the extended aeration system.
