Dissolved air fotation
Dissolved air fotation is one of the most effective methods with speci c gravity of close to 1.0 from water. Dissolved Air Flotation is liquid/solid or liquid/liquid separation process to remove tiny suspended solids with any density close to water, colloid, oil and grease etc.
DAF Advantages
• Ability to handle variable solids loading (can adjust air ow)
• Can provide high oat concentration (good thickening)
• Can remove low density particles with long settling periods.
• High BOD removal
• Less unpleasant smell
• Low sensitivity to variations in water quality and ow
• Easy operation
• Low maintenance and long life
• High rise velocity and Less retention time (small footprint)
• Less chemicals required
• Less construction, maintenance and chemical costs (30% to 50%)
FanNiroo abilities
• Design, engineer, manufacture, construct and commission with various economical capacity.
• Manufacture in high industrial ow levels.
• Design in high concentration of TSS. (3000 ppm and more).
• Design simultaneous separation of TSS and oily waste.
• Make inline injection of chemicals (Coagulant- Flocculants) using Flocculation pipe.
