oxygen) from the water that lifts particulates out of solution. Like dissolved air floatation, this captures oils, grease, and light particles, and carries them to the surface. Foam is skimmed off the surface, solids are scraped from the bottom, and clarified water is discharged from the center of the reactor.
Application:
Why: Pretreatment technology to remove particles and colloidal material before further membrane treatment.
Where: Both mobile on-site systems for water recycling and off-site facilities. Target Contaminants:
• Trace particulates • Oil and grease • Biological and organic constituents • Large molecular weight organic compounds.
Benefits:
• Small footprint • Modular and mobile systems • Consistent constituent removal Limitations:
