Abstract
Oily and/or solids-containing water is clarified by chemical treatment to form flocculated and agglomerated solid phases and a clear water phase. In the clarification process, microbubbles of air or other gas are introduced at atmospheric pressure, via an eductor or other suitable device, together with a flocculant. During the subsequent formation of floes and their agglomeration into larger masses, microbubbles become entrained within and adhered to the solid flocculated materials. The resulting masses are very buoyant and easily separated from the water via a variety of approaches that include skimming, decanting, filtration, and screening. This process results in a solids phase that may be disposed of as waste, if desired, and a highly clarified water phase.
