Application of Rotary Screens, Biological Contactors, and Gravity Plate Settlers to Treat Wastewaters in Hoboken and North Bergen, New Jersey,
Abstract
The Hoboken pilot plant was operated on a full-scale facility by using rotoscreens for primary treatment. Rotating biological contactors or trickling filter for carbonaceous removal, and LAMELLA gravity settler for biological solid and liquid separation. The results showed this flow through system can successfully treat sewage at the effluent concentration of both BOD and suspended solids less than 20 mg/1. The biomass sloughed from the media of rotating biological contactor or trickling filter into the mixed liquor, were easily settled down on the LAMELLA gravity settler without causing any problem on the settler, such as biological growth on the plater of the settler. In stage analysis, the operation of the rotating biological contactor at two stages showed the best results, either in the BOD removal efficiency of sludge production, while comparing with 3, 4 or 5 stages.
