ABSTRACT:
An upflow, buoyant media filter for industrial and municipal water and wastewater treatment is disclosed. The filter bed is supported in a tank such that there is defined an influent reservoir below the filter bed and an effluent reservoir above the filter bed. By inducing a continuous circulating flow of influent within the influent reservoir, the waste is slowly agitated allowing it to coagulate. As the waste particles are carried to the relatively quiescent areas near the perimeter of the tank, those that are heavy enough settle to the bottom of the tank. The lighter particles are carried along in the circulating flow to continue the coagulation process. Waste particles which do not settle out are ultimately removed by the filter media. As the waste particles build up on the surface of the filter media, they agglomerate. As their density increases, these particles tend to drop off of their own weight or may be scoured off by the circulating flow of influent. This self-cleaning process permits less frequent backwashing of the filter.
