Heron Innovators has introduced its advanced Suspended Air Flotation (SAF) system for efficiency and effectiveness in solid/liquid separation in the food, dairy and animal products industries. The Suspended Air Flotation is designed to enhance separation efficiency, resulting in cleaner effluent and drier skimmed solids. Additionally, it can also reduce operating costs through lower energy consumption, decreased flocculant and coagulant usage, and reduced operator attention and maintenance requirements. SAF systems occupy a small footprint while increasing hydraulic flow and solids loading capacities.

SAF utilizes charged microbubbles, known as aphrons, that do not dissolve. An aphron is a double-walled bubble, 7-25 µm in size, that will not coalesce and has a greater surface area and longer lifespan than traditional DAF bubbles. Aphrons can possess either a cationic or anionic charge. This electrostatic affinity and the resulting surface tension advantage allow aphrons to effectively adhere to, attract and encapsulate contaminant particles.
