Dispersed Air Flotation for the Removal of Solids from Water

Nina Lolo Maclayton, William J. Zimmerman

Abstract


The quest for clean drinking water is fundamental to our existence as without it, there is no life. This research exploits the feasibility of using principles of the state-of-the-art flotation technique for solid-liquid water clarification.  Dispersed air flotation [DAF] as a separation technique, involves dispersing (scattering) compressed air at high pressure into water. A fluidic oscillator is employed to generate minute micro-bubbles from a 20 microns pore sized ceramic diffusers at a lowered pressure of 60L/min thereby reducing energy costs. Under continuous operation, the performance of micro-bubbles generated with the fluidic oscillator was compared to micro-bubbles produced without the saturator system. Results indicate a better efficiency of removal by the bubbles generated using the fluidic oscillator at the rate of 60. 6%.

Key Words: Dispensed Air Flotation, Removal of Solids from Water, Chemical Process, Chemical Engineering, Clean Water, Water Purity, Health as part of life.
