Specifications
Feed System:
7.5 HP, 250 gpm pump with 4-in. magnetic flow meter,
pH control system with acid and caustic PID Loops
Floc Mixer:
Serpentine-Style Floc Mixer, 4″ diameter, Plug flow, 100′ long, schedule 80 PVC.
Flotation Tank:
Model CF-125 ClearFloater™ Cross-Flow Flotation Cell with ClearMixer®, chain and flight skimmer, solids hopper, adjustable stainless steel weir, and observation decking.
SAF® Generator:
Model F50 (13.6 gpm froth flow rating).
Ancillary Equipment:

Results
-
SAF® demonstrates over 30 times the capacity of a conventional primary clarifier. Algae removed from pond less than 0.5 NTU. MLSS thickens using less polymer and with greater solids capture.
