Krofta Air Dissolving Tube

Key to all Krofta DAF systems is the Krofta Air Dissolving Tube (ADT). By eliminating the need for large volumes of air and water used by typical pressure components, the ADT uses air dispersion technology and centrifugal force in place of just volume and gravity. In operation at thousands of installations worldwide, the Krofta ADT is a central component to all Krofta DAF solutions, and can be retrofitted on any type of DAF clarifier.

Faster air dissolution. Lower retention time.
One of the essential features of the ADT is dissolving air into the water faster than other systems. The DAF system pumps and disperses compressed air into the ADT, which results in lower retention time of only 8 to 12 seconds. The flow pattern additionally creates a vortex, which eliminates undesirable air, creating better overall performance.

Reduced maintenance. Increased performance.
Designed for optimum performance, the ADT provides mechanical features that offer lower maintenance and higher efficiency. From meeting different recycle requirements of varying waste streams to eliminating excess air in the tube the ADT can generate 30-70 micron bubbles well-suited for DAF operation.
