Circular Clarifiers Offer a Proven Solution for Wastewater Treatment

Circular clarification is one of the most popular and proven processes used to treat contaminants for removal in wastewater. While some systems settle solids out of the liquid stream by gravity, others use flotation methods to float the solids to the top to be skimmed away.
