Algae control in wastewater clarifier
July 2007, Shenandoah, Virginia USA.
We decided to “upsize” the LG Sonic® unit due to the turbidity in the clarifier to produce as strong a signal as possible across the unit. The installation involved placing a rigid conduit on the inside sidewall of the clarifier and the LG Sonic® mounted to the rear of the skimmer trough underneath the path of the rotating arm. The rotating skimmer easily passes over the conduit due to a rubber scraper at the end of the skimmer arm.

"Our costumer typically cleaned his 3 clarifiers each week which took 4-5 hours total. He now cleans all three clarifiers once a month. A visual notation was made that noted the improved clarity of the water inside the clarifier. The city also noticed a slight reduction in their chlorine demand before the discharge to the creek."
