Pulsar Measurement - Model Sludge Finder 2 -Sludge Blanket Level Control

Sludge blanket level control is a crucial aspect of any process that includes primary settlement tanks, secondary settlement tanks, tertiary settlement tanks either with stationary or traveling bridges, clarifiers, gravity thickeners, or sequencing batch reactor systems. Sludge blanket level measurement works by measuring the distance between the sludge blanket surface and the water level. Once the sludge has reached the required density, the accompanying controller will then switch on the pumps and pump the sludge through into digesters, ready for the next treatment stage.

Effective sludge blanket level measurement can help treatment plants or industrial processes to generate their own electricity, ensure that pumps are being used efficiently, ensure that excess sludge is not being pumped into our local water sources, aids with compliance to health, safety, and environmental regulations, and finally, ensures that further sludge handling processes such as thickeners and dewatering equipment are all performing to their maximum with the correct concentration of sludge.
