Which treatment method is abbreviated as DAFT?

The treatment method abbreviated as DAFT stands for Dissolved Air Floatation Treatment. This process is utilized in wastewater treatment to separate solids from liquids based on density differences. In DAFT, air is dissolved into water under pressure, creating small bubbles. When the pressure is released, these tiny bubbles form and attach to suspended solids in the wastewater, causing them to rise to the surface. This flotation effect allows the solids to be removed easily, resulting in a clarified effluent.

DAFT is particularly effective for treating wastewater streams with high concentrations of suspended solids and fats, oils, and grease, making it an important method in various wastewater treatment applications. Understanding this process is essential for recognizing how different methods can enhance the overall efficiency of wastewater treatment systems.
