Abstract

Nematode populations were studied during a 15-week period with samples taken from possible breeding sites at the Ruston, Louisiana, wastewater treatment plant. The trickling filter was found to be the primary breeding site and was the treatment responsible for the majority of nematodes found in the final effluent. Results showed that nematodes were removed in secondary clarifiers and final settling tanks. More nematodes were removed in the dilution stream under conditions of high flow than during normal stream flow. The settling of solids was found to be responsible for the removal of nematodes in suspension.
