Abstract
A method and system for optimizing the operation of a trickling filter. Optimization is obtained by using a pair of controlling devices, a timer and an electric motor in combination. The electric motor rotates the distributor mechanism of the trickling filter in response to signals transmitted thereto by the first and second controller. The timer activates the first controller during operation to provide a SK value of between 25-500 mm/pass. During non-peak hours, the timer activates the second controller for flushing the biomass used in the trickling filter operation. The flushing is accomplished at SK values of between 200-1000 mm/pass. A method is also disclosed incorporating the above system.
