DAF Solutions

Cequesta Water has 25 year of experience in design and installation of circular COCO DAFs (counter current Dissolved Air Flotation).

The advantages of COCO DAFs are numerous: Higher rates 10-20 m/hour; enhanced flocs capture in bubble blanket; reduced flocs damage; reduced flocculation times; smaller footprint and lower capital cost.

Naturally, this technology is seen more with circular vessels and when encountering large flows this approach can limit the attractiveness of the technology.

We at Cequesta Water, developed the solution for this limitation and now offer  low rectangular profile design, enabling more compact solutions, suitable for any transportation means.

Technology – counter current air floatation with integrated media post filtration.
