Abstract |
The treatability of feedlot runoff was investigated utilizing an extended aeration type system. The operational parameters studied were evaluated on a basis of COD removal and the effects of the treatment system on the turbidity. COD reductions of 60% or more were obtained at retention times of three days or more and at MLSS values of 2,000 mg/l or more. Increased retention times resulted in increased COD reductions. The color of the runoff was affected only slightly by aerobic treatment regardless of the retention time. However, significant reductions were obtained by heavy dosages of iron and aluminum coagulants. COD analysis was superior to the BOD5 determination in evaluating the efficiency of treatment and the strength of feedlot runoff. |
