Overview

The Suspended Air® Flotation (SAF®) system, delivers exceptional clarification and solids removal using electrostatically charged micro-bubble froth — containing approximately 40% air by volume.Unlike conventional Dissolved Air Flotation (DAF), the SAF® process does not rely on gas solubility or saturation physics. Instead, it uses surface tension modification and electrostatic attraction to efficiently capture, attach, and lift suspended particles.The result is a compact, reliable, and energy-efficient flotation solution for municipal and industrial water treatment applications.

Benefits

Superior particle removal efficiency through electrostatically charged micro-bubbles
Compact footprint with higher capacity and faster rise rates
Reduced chemical and energy consumption
Plug-and-play installation for rapid startup
Low maintenance and long-term durability
Retrofit compatibility with existing flotation systems
