The project evaluated (full-scale) an extended aeration biological treatment system on salmon processing wastewater. During the first years evaluation the detention time in the aeration basin averaged 17 days (range 3 to 49 days). This was due to the plant processing significantly less salmon than anticipated. The BOD removal averaged over 90 percent (effluent about 50 mg/l). A smaller aeration tank and settling tank were designed and installed to evaluate shorter and more reasonable detention times. The detention time in this system ranged from 0.3 to 9.2 days and averaged 4.4 days. BOD removal averaged about 80 percent. The effluent BOD and SS concentrations averaged 128 and 86 mg/l, respectively. The economic evaluation indicated the total treatment costs per kkg of large and small salmon processed were $5.76 and $9.55, respectively.
