Sludge Blanket refers to the formation of sludge at the bottom of a settlement tank. This sludge builds up over time, and when it reaches the required level, it is then pumped to the next stage of the treatment process.
By allowing the sludge blanket to form at the bottom of a settlement tank or clarifier, it allows for the removal of small particles such as dirt, bacteria, and metals to be removed from the water. Effective sludge level measurement can help treatment plants or industrial customers generate their own electricity, as many large sewage treatment works will use the gas produced in digesters to drive turbines that generate electricity. Additionally, operators can ensure that sludge extraction pumps are used efficiently, and that excess poorly settled sludge does not was out into effluent paths, preventing costly overspills and regulation breaches.
Pulsar Measurement’s Sludge Finder 2 has been specifically designed for sludge blanket level measurement. It replaces old manual techniques that prove unreliable and are a risk to the health and safety of staff on site. The two-part system operates ultrasonically through a liquid and features a self-cleaning sensor to wipe away sludge buildup. View more information on the Sludge Finder 2 product below:
