SIGMADAF - Dissolved Air Flotation System DAF Clarifier
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 wastewater that are introduced at one end of the apparatus and ejects the 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.
SIGMADAF - Dissolved Air Flotation System for Low to Medium Solids Loaded Wastewater Flows. DAF Clarifier
The FPBC flotation system is a high-built separator designed to treat low to medium loaded waste waters, even those containing low buoyancy particles.
The system is based on the counter-current flow principle, through an inclined corrugated plate pack. Water is introduced into the system in a cross-flow configuration which effectively reduces the distance that solids have to travel to be separated effectively. Within the compact separator, a thin layer plate pack has been installed to obtain a maximum separating surface area. The separation velocity is determined by the flow (Q) and the effective plate surface (S), therefore particles which achieve a higher rising velocity (by micro bubble aeration) than the overflow rate (Q/S), will be separated.
Due to the application of the plate separating technology, maximum separation efficiency is obtained with very
low overflow rates, making the separators compact and effective.

SIGMADAF - Dissolved Air Flotation System. DAF Clarifier
The FPHF flotation system is a separation system, improved from existing plate pack technology which utilises a combination of cross flow and counter-current flow. This technology was originally developed for special applications for high flow volumes with a substantial suspended solids content. Settling particles can be separated with a relative high efficiency by the FPHF.
High flow volume demands a better flow distribution. The inflow surface of the plate packs is equally divided against laminar flor proportionality within the system. In practice, it shows an attainable volume treatment above 100%, compared to conventional plate separators, which have mostly an overflow rate of at least 3m3 per m2 per hour.
