Dissolved air flotation (DAF) is the practice of removing suspended solids, oils and other contaminants via the use of atmosphere bubble flotation. Air is excavated into water, mixed with the wastestream and released from remedy while in intimate contact with the contaminants. Air bubbles form, affix into the solids, then enhance their buoyancy and float the solids into the water's surface area. A percentage of this clean effluent is recycled and supersaturated together with atmosphere, combined with all the wastewater influent and injected into the DAF fracture chamber.
The dissolved air will come out of solution, providing millions of microscopic bubbles. These bubbles attach to the solids and float them into the outside where they're mechanically skimmed and taken out of your tank. Even the Pan America Environmental dissolved air flotation methods have been intended to remove oils, fats and grease (FOG), suspended solids, food/animal production/processing wastesand industrial wastes, hydrocarbon oils/emulsions and a lot different pollutants. Clarification speeds as large as 97% or maybe more may be accomplished using our dissolved air flotation methods. Chemical pre-treatment can often help to enhance the operation of both contaminant elimination.
As one of daf manufacturers, we can provide daf water treatment system with competitive price.
