    3.1 Results for dissolved air flotation (DAF) with the optimum concentration of KCl and NaCl (1M) Figure 1 shows the percentages of cyanobacterial cells removal for the optimum concentration of coagulant solution, using extraction with KCl (1M) and NaCl (1M), obtained in the C F DAF process for different initial turbidity values.DAF's Increasing Popularity. Dissolved Air Flotation has been used for decades in the treatment of industrial wastewater and due to its high efficiency is gaining a large user-base in other industries for the removal of oils, fibers, blood, and other light items in suspension that do not settle well under normal operating conditions. By use of a special Impeller design, the pump creates.Ellis DAF units use optimally designed microbubble generator pumps. These microbubbles rapidly float the floc particles to form the surface sludge blanket onto the surface of the flotation cell. The floating solids are skimmed towards the front of the DAF and collected in a solids chamber.

    Dissolved Air Flotation In Industrial Wastewater

    Currently, flotation in conventional cells is not being used in North American board mills but there is a definitive trend to include it in the separation steps [1–5]. Some key limitations to the installation of conventional flotation cells in the OCC recycling process are high flotation losses [3] and large floor space requirement.Cells and details of this design will be discussed later in this article.
