| Abstract |
The applicability of a full-scale, six-stage trickling filter plant was investigated for the treatment of waste from a multiproduct organic chemical plant. Reductions of BOD per unit volume of packing indicated that the series design of the system did not lead to stage-wise acclimation of the microorganisms or enhanced BOD removals. Tests to determine BOD removal mechanisms in the system indicated that air stripping and biological mechanisms both contributed significantly to the total observed reduction. Effluent recycle considerably improved filter performance. However, 600 percent recycle was required for an approximate 90 percent reduction of BOD at a hydraulic loading of 2 gpm/sq ft (0.08 cu m/min-sq m). Bench-scale activated sludge investigations showed that this process could be used successfully for upgrading the trickling filter system. |
