    The feed water to the DAF float tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to coagulate the colloidal particles and/or a flocculant to conglomerate the particles into bigger clusters. A portion of the clarified effluent water leaving the DAF tank is pumped into a small pressure vessel (called the air drum) into which compressed air is also introduced. This results in saturating the pressuri

    Saturator efficiency is 100 times the amount of air measured in the recycle water divided by the amount of air that could be dissolved theoretically. Air saturated water is returned to the flotation tank through a series of nozzles or needle valves to give a sudden reduction in pressure and release of air bubbles in a white water curtain.

  • Dissolved air flotation - Wikipedia

    Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter ...

  • Design and Sizing of a Dissolved Air Flotation Separator

    If using the smallest possible plate spacing were the answer to building the most efficient DAF, we would be building dissolved air flotation systems with 1/8" plate spacing, or smaller. Unfortunately, this is not the answer. Other considerations come into play. In actual practice, a plate spacing of 2" is the smallest plate spacing recommended. Many other issues come into play, such as excessively high cross sectional
