Series F Suspended Air® Emulsion Generator

Operation and Applications

Suspended Air® Flotation (SAF™) outperforms Dissolved Air Flotation (DAF) because each Suspended Air® bubble is a working bubble, with an electrically-charged surfactant film ready to attach and stick to oppositely-charged floc particles. The combination of surface tension advantages and electrostatic attraction results in a SAFTM bubble that has a much greater affinity (100 to 1,000 times greater) for developing a particle when compared to a DAF bubble. This results in extremely high rise rates and a stable float characteristic, and makes it possible to operate a flotation process at 10 times the hydraulic loading rate and 10 times the solids loading rate of DAF.

An existing DAF can be retrofitted to perform as a (SAF™): Suspended Air® Emulsion Generators are replacing SAF pressurization systems, increasing the hydraulic and solids loading capacity of an existing DAF flotation tank by 3 to 4 times without increasing footprint and without modifying the existing tank. Generally, retrofits have the added benefit of significantly reducing connected horsepower thereby substantially reducing greenhouse gas emissions.

Standard Features

Unit is supplied pre-piped and pre-wired, with removable side and top cover panels, a NEMA 4X control panel, and connection points for electrical power, makeup water, frothing agent, and emulsion output.

Sealed Generator Module: Stainless steel, fully seal welded, carrying an extended warranty of five years against defects in materials or workmanship. Patented technology.

Frothing Agent Metering Pump: Pulsed-diaphram type, manual stroke length adjustment. Control signal input for pulse frequency adjustment proportional to emulsion flow rate.

Instrumentation and Controls: Polypropylene flow sensor, flow rate and totalized flow display, and control signal output. Float and solenoid water level control. “Warm-up” time delay on emulsion output solenoid valve.

Recycle Pump: Rotary lobe or gear positive displacement pump coupled to a 3-phase, 460v electric motor with electronic variable speed drive and gear reducer on Models F8 through F200. Single phase 230v motors available as an option on Models F8 and F25. Model F2 has a 110v single phase motor.
