Technical Article: Liquid Level/Interface Monitoring In Flocculant/Sludge Control
By Steven Craig, Sr. Member Technical Staff, Fluid Components International (FCI)
In municipal and industrial wastewater treatment plants, sludge clarifiers are utilized to separate solids from the water treatment effluent system by introducing air and flocculants. This process results in the sludge rising to the top of the pond or tank and spilling over a weir into a separate collection area. When selecting a sensing a technology for liquid level/interface it is important to not only consider the process media and desired performance criteria, but the plant environment is important too.
