Dissolved Air Flotation (or D.A.F.) is a process in which tiny air molecules bind themselves to solid particles, forcing the solids to float to the surface of a holding tank where they can be skimmed from the surface.
Through the combination of Cornell’s patented Cycloseal® and an innovative impeller design, the Cornell D.A.F. pump creates a sub-atmospheric pressure region within the seal chamber that allows compressed micro-bubbles to form. They are then dissolved in the pumpage. This process helps to eliminate the need for an air saturation tank and compressor that is required by many other flotation systems. The innovation of Cornell’s D.A.F. pumps enhance the performance of many existing D.A.F. systems and sets the client up to save money due to the efficiency of the new designs.
