SIGMADAF - Model FPHF -Dissolved Air Flotation System. DAF Clarifier

The FPHF is a high-performance system with a number of distinct features. It includes a single movement separator, which rotates against the hydraulic flow of the water, helping to minimise the skimming distance of the floated sludge
and eliminating solids carry-over. It creates a sludge with a dry solids content 3 to 4 times greater than a conventional system. The result of which, is a reduction in the need for and scale of any future treatment, such as de-watering or drying,

consequently resulting in reduced follow-on costs.

The bottom sludge within the system is held in place
as it thickens and partially de-watered by the shaftless auger system. This enables the operator to control the thickness of the sludge, eliminates the early-removal of solids and reduces the build-up of sludge. The residual sludge is then transported to a central discharge point and removed via an automatic pneumatic valve. This discharge cycle is self-cleaning, and any particles adhered to the walls or sides of the system will loosen and follow their initial flow path.

The system as standard, is fitted with an aerator, recirculation module, a pneumatic switch and a control panel to enable the air supply to the aeration module and sediment discharge valve to be controlled.
