Why a Remarkably Rapid Rise Rate Makes all the Difference in Solids Separation

Ferric SAF-DAFWhen it comes to the use of dissolved air flotation, a rapid rise rate of flocculated solids makes all the difference. This is true for a number of industries relying on the technology, and the difference Suspended Air® Flotation makes is significant.

With this technology, each bubble is covered with a chemically active film that strongly attaches itself to the flocculated solids and creates a remarkably high rise rate and very efficient flotation.  A routine aspect of all of our applications, this not only results in a high loading rate, but also a smaller footprint.

The process works extremely well in food processing, where suspended solids need to be separated and removed. Fruit and vegetable canneries, meat processors, snack food manufacturers, and dairy processors rely on this process in their production.

As an example, tomato processors often face challenges associated with solids collected in a tank: they accumulate over time and become difficult to manage. Properly removing the solids means creating more space in the holding tank, as well as making for more efficient and cleaner irrigation. Another industry/area to benefit from the technology is breweries, which rely on separation of solids byproducts from the treated liquids. As well, fruit canneries benefit from Suspended Air® Flotation for removal of solids from the fruit wash water and flume water, as well as from process equipment cleaning.

The fact is, compared to Dissolved Air Flotation (DAF), which depends on physical entrapment and a weak surface bond to float the solids, SAF™ causes flocculated solids to rise over ten times as fast. Anyone relying on solids separation for their business—whether fruits and vegetables, beer, or something else altogether—knows that this order-of-magnitude increase in rise rate can make all the difference.
