During this process, the surface of weir teeth, channel and concrete trough of the clarifier accumulates a thick layer of lime that restricts the water flow and slows down the cleaning process. To remove the algae and lime accumulation, the wastewater facility typically would have to drain the water of the clarifier until the water gets below its weir teeth. When the surfaces are exposed...
