the two tanks was done in a rather unconventional manner. The main transfer of water from T 04 to T 05 flowed out a nozzle located near the base of the tank. In addition to this, an overflow near the top connected both tanks. As a result, in the event of high levels within the first tank, the oiliest water was transferred to the second tank.

Flotation: DAF, IAF, SAF By Dave Christophersen, Vice President/Technical Manager Flotation is a method of separating solids or liquids from water by introducing fine gas bubbles.

Normally the setup is a two stage system with up to flotation cells in a series. Similar to the process found in mining, the recycled paper is mixed with water to form a thick slurry. This slurry is then heavily mixed and injected with air along with hydrophobic chemicals to bind to the unwanted particles that need to be removed from the slurry.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5.

The Jameson Cell consistently produces fine bubbles and intense mixing between air and slurry. This means fast, efficient flotation. While the principle of using air bubbles to recover particles is the basis of the technology, it is the way air bubbles are generated and how the bubbles and particles interact that make Jameson Cells unique.

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
