Dissolved Air Flotation biofilter

Dissolved Air Flotation (DAF) has been known as one of the most effective and robust ways to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), fats, oils and grease (FOG), phosphorus (P) or nutrients from industrial wastewaters.In response to variations in industrial activity, variations in wastewater and water streams and the ever-demanding customer requirements, Nijhuis

    Dissolved Air Flotation ( DAF System) is a water treatment process that clarifies wastewater (or other water, such as river or lake) by removing the susupended solids or oil & grease. It is widely used in the waste water treatment for solid-liquid separation, it can remove the suspended solids, oil & grease and colloidal substance effectively

    Jun 18, 2020 How DAF works. Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening.. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by settling

    Contaminants are removed through the use of dissolved air in the water solution produced by injecting air under pressure in the flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter, causing the suspended matter to float on the surface of the water where a skimmer may then remove it
