ABSTRACT:
A method and system for optimizing the operation of a trickling filter. Optimization is obtained by using a controlling device and a variable speed drive in combination. The drive motor rotates the distributor mechanism of the trickling filter in response to signals transmitted thereto by the controlling device. The signals received are either based on the influent flow rate or a pre-programmed system representing the above. In response to these signals, the speed of rotation of the distributor is continually varied to provide a SK value most conductive for (1) reducing the BOD and ammonia levels present in the wastewater influent, (2) removing excess bio-mass attached to the media used in the filter and (3) driving the organic food materials deeper into the bio-mass. SK values of between 5 to 100 mm/pass are used for normal operation and a SK of 100 to 1000 mm/pass for flushing during non-peak hours. An intermediate SK value is used to drive the organic feed deeper into the media. This SK value may vary over abroad range depending on the concentration of organic material present in the feed. Normally the optimum SK value will be between about 10 and 150 mm/pass. A method is also disclosed incorporating the above system.
