White water clarification

Krofta DAFs have been used for the past forty years as a save-all for whitewater clarification. These applications have been as a standalone device or in parallel to other devices used as save-all.

Krofta DAF clarification for whitewater in the pulp & paper industry

Krofta Supracell DAF

The most common design of Krofta DAF is the SPC or Supracell, Krofta’s circular designed DAF. The SPC design has a large separation area to handle higher solids loading applications.

Krofta Air Dissolving Tube

In some of the newer tissue and towel mills, the SPC has been designed with two ADTs (Air Dissolving Tubes) to be able to quickly switch back and forth between the manufacture of tissues and towels where the whitewater solids concentrations will vary depending on the type of product being manufactured. One DAF can be designed with the flexibility to handle two different whitewater needs.

Krofta Sludge Blanket Controller

The SPC design can be supplied with a SBC (Sludge Blanket Controller), which is a proprietary device that controls the thickness of the DAF float maximizing the percent solids that would be returned back to the process.
