Research at Fayette, Missouri on oxidation ponds has shown that the BOD in the treated effluent varied from 30 to 53 mg/l with loadings from 8 to 120 lb.

Since experience indicates that effluents from oxidation ponds do not create major problems at these BOD concentrations, the goal for the effluent quality of the accelerated treatment system was the same as from conventional oxidation ponds.

Recent studies by Weston and Stack had indicated that a turbine aerator could be added to an oxidation pond to increase the rate of oxygen transfer.

Their study showed that it was possible to transfer 3 to 4 lb of oxygen / hr. / hp.
