DAFFPAC

The SIGMADAF FPAC is a high performance and quality system with different specialist features.

Perfect for working with small and medium flow rates and when very high contaminant loads require removal. They are a low built cross flow separator with a lot of free surface area where the floated mud can accumulate.

SIGMA FPAC

The FPAC flotation system is a large surface air flotation system with cross flow separation. The system has been designed to treat wastewater flows heavily loaded with solids that need significant amounts of free surface area for successful flotation and separation (up to 40kg of solids per m² of free surface area inside the system can be treated). 

Dissolved Air Flotation (DAF) system processes wastewaters that are introduced at one end of the apparatus and ejected as clean water at the other end.

DAF technology is utilised to remove oils, grease, solids and suspended flocculants that do not possess sufficient buoyancy to float; or where an emulsion of oils and solids (with increased density) require air flotation to enhance the separation process. 

The use of micro-bubble flotation technology (30 to 50-micron range) increases efficiency, as smaller bubbles easily adhere to equal-sized or larger particles, boosting the overall effectiveness of the system.

The FPAC is a high-performance system with a number of distinctive 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.
