Standard Specifications
APPLICATION - Series CF Flotation Separators are designed to be used in a Suspended Air Flotation (SAF™) System, properly matched with a Series F Suspended Air® Emulsion Generator to treat the flow rate and suspended solids content of the particular water to be treated.
Hydraulic loading rates as high as 15 gpm per square foot of flotation area have been sustained in test runs. The Series CF is also rated for solids fluxes as high as 15 lb. per hour per square foot of flotation area. This results in a footprint less than 30 percent of DAF for the same treatment result.
Flotation treatment can be interrupted for extended periods of time and re-started quickly without loss of treatment efficiency, because the floated solids remain on the tank surface.
FLOTATION TANK DESIGN - The Series CF design has been developed to realize the full advantage of the extremely high rise velocities and stable float characteristic of flocculated solids having Suspended Air® bubbles attached.
The inlet passes through an agitated flocculation chamber, and the inlet to the flotation area is distributed evenly across the tank length. The skimmed surface is typically longer than it is wide. The solids are skimmed off immediately after reaching the surface, without allowing a mat of solids to build up.
Skimmed solids are scraped up an inclined beach section to the discharge chute. Clarified effluent passes underneath a deep baffle, overflowing a full-width adjustable weir to the effluent receiving box.
EQUIPMENT FEATURES AND OPTIONS
Tank and Support Materials: A36 carbon steel, minimum 12 gauge, welded construction. Stainless steel available as an option.
Flocculation Chamber: Mechanically agitated compartment within the flotation tank, mixer shaft direct driven by a variable speed gearmotor. Provides for effective blending of Suspended Air® Emulsion and additional polymer with influent coagulated / flocculated wastewater.
Mechanical Skimmer: Chain and flight, stainless steel flights and shaft, thermoplastic sprockets and pintle chain, with the drive sprocket direct driven by a variable speed gearmotor. Timed on / off cycle can be supplied as an option.
