Abstract: A screen filter for wastewater applications includes a chain tensioning system. The chain tensioning system provides a tensioning force for a screen filter chain. The chain tensioning system includes a chain adjuster device configured to tension the screen filter chain. The chain tensioning system additionally includes a sensor configured to provide a signal representative of a load applied by the chain adjuster; wherein the chain adjuster device is configured to apply a force in a direction that tensions the chain and wherein the signal provided by the sensor is representative of the force.

Abstract: A treatment assembly removes and cleans solids located in a stream of liquid. A screen filter has a lower portion located in a channel to remove the solids from the liquid flowing through the channel. Once removed, the screen filter deposits the solids into an agitator assembly. Wash water is fed continuously into the agitator assembly, and the agitator within creates turbulence to clean the solids. The wash water and solids are continuously removed from the agitator assembly for further processing.
