DAF of Organic Cheese Factory: From wastewater to clean water outlet
DAF in Dairy Wastewater Treatment: A Technical Approach Dairies and cheese production facilities generate wastewater with a high organic load, increased content of fats, proteins, and suspended solids. The typical parameters that characterize this wastewater are: BOD5: 1,500 – 3,000 mg/L COD: 3,000 – 6,000 mg/L Total Suspended Solids (TSS): 500 – 1,500 mg/L Fats,…
Modernization and Expansion of Wastewater Treatment Plant with the Addition of a DAF System at “GREKA”
A new-generation DAF system with a capacity of 20 m³/hr was installed in the existing wastewater treatment plant of the company. The system consists of two distinct sections: (a) Chemical Treatment, and (b) Flotation – Sludge Removal with a Surface Skimmer. It removes up to 75% of the organic load in the form of suspended solids. The…

DAF (Dissolved Air Flotation): Advanced Solid-Liquid Separation Technology
DAF (Dissolved Air Flotation) is an advanced solid-liquid separation technology widely used in wastewater treatment and industrial effluent processing. The process is based on the dissolution of air under pressure into water, forming microbubbles that attach to suspended solids, lifting them to the surface. At the surface, a floating sludge layer is formed and mechanically…
The Role of DAF Effluent in Enhancing Biological Treatment Performance
The effluent discharged from the Dissolved Air Flotation (DAF) system, when the unit operates correctly, represents a critical stage in wastewater treatment—particularly in industrial and municipal facilities. The DAF system is employed to remove suspended solids, oils, and greases through a process where fine air bubbles bind with particles, causing them to float to the…
Chemical Treatment Using DAF (Dissolved Air Flotation) in Dairy Wastewater
Chemical treatment through Dissolved Air Flotation (DAF) is an effective method for removing fats, proteins, and suspended solids, which are typically elevated in dairy industry wastewater. The process involves the addition of chemical coagulants and flocculant aids—such as polymers or iron and aluminum salts—that facilitate the agglomeration of pollutants, enabling them to attach to the…
