dissolved air flotation

[də′zälvd ‚er flō′tā·shən]
(chemical engineering)
A liquid-solid separation process wherein the main mechanism of suspended-solids removal is the change of apparent specific gravity of those suspended solids in relation to that of the suspending liquid by the attachment of small gas bubbles formed by the release of dissolved gas to the solids. Also known as air flotation.
