Air Dissolving Tube (ADT) Krofta DAF

The KROFTA Air Dissolving Tube (ADT) has been in use on Dissolved Air Flotation (DAF) clarifiers since the 1970s. Since that time, thousands of ADTs have been put into operation, producing dissolved air in a recycle stream on a wide variety of applications and types of equipment. Before Dr. Milos Krofta invented the ADT, Krofta had used
