Abstract

Nine primary facultative ponds were investigated. Findings showed that higher HRTs didn't result in better effluent quality. Hydraulic and organic loads were smaller than those foreseen in the designs. Hydraulic and organic per caput contributions were low, resulting in idle capacity. Mean BOD, COD and solids suspended removal were 79,70 and 52%, respectively. Removal constants for hydraulic regimes of complete mixing and plug-flow converged with increase of HRT.Computation k constant in plug-flow was shown more appropriate. Alternative design pathways were developed for primary facultative ponds by using hybid approach (analytic and empiric models).
