May 20, 2021 Dissolved air flotation (DAF) is a unit operation capable of removing solid or liquid contaminant particles present in a liquid phase. At the beginning of its use (the early 1900s), DAF was widely used in the ore processing industry as a method of separating mineral ores (Edzwald 1995).Sixty years later, water and wastewater treatment plants began applying DAF to remove color, natural
