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.
