The present invention relates to a method of generating white water for use in Dissolved Air Flotation (DAF) processes, the method comprising the steps of forming a reduced pressure air/water mixture; subjecting the air/water mixture to an elevated hydrostatic pressure in a water column to achieve substantial dissolution of air in water; removing the air in water solution from the elevated hydrostatic pressure region to form a super-saturated air in water solution; and introducing the super-saturated air in water solution into a process stream wherein the air is released from solution as white water micro-bubbles while in intimate contact with contaminants to perform Dissolved Air Flotation.
