REMOVAL PROCESS OPTIONS
Whereas mechanical oils will eventually float in water, emulsified oils never settle. Depending on the oil's chemical composition, Kontek applies the most suitable removal process.
Dissolved Air Floatation (DAF)
DAF is an appropriate process when the oil or grease in less dense than water or has neutral buoyancy. Millions of micro-scale bubbles, referred to as "whitewater" float upwards from the bottom of the tank. Little clumps of the oil or grease, commonly called flocks, are pushed to the surface as the micro bubbles rise. The floating contaminants are mechanically skimmed away, leaving oil-free water at the bottom.
Emulsified oils remain suspended in water because they have a filmy barrier that lowers the particles' surface tension. Lowering the solution pH by adding acid breaks the oil's emulsion, allowing unwanted oil and grease particles to float to the surface.
De-emulsified oils are removed mechanically on oleophilic plates that permit flotation separation
