The process of using SAF® to bind particles is more effective than traditional flotation methods due to a combination of micro-bubble surface tension and charge.
The SAF® Generator uses either anionic or cationic surfactant tailored to the prescribed chemical regiment to produce charged microbubble froth that is approximately 40% air by volume, which is considerably higher than with competing technologies, e.g. dissolved or induced air flotation.
Surfactant is fed at a concentration of 0.15-1ppm, depending on the waste stream. Most or all of the surfactant is skimmed and discharged with solids from the flotation cell. Increased rise rate and stability of floated solids result in more effective separation and smaller footprint than competing technologies. In addition, the charged microbubbles are produced independent of the process stream and are therefore unaffected by process temperature. This also provides very quick start-up of treatment processes (usually < one minute).
