Pre-aeration in the equalization tank: A critical stage in biological wastewater treatment
Effective wastewater treatment relies on a series of stages that ensure the proper operation of the plant and the protection of the environment. One of these stages is pre-aeration in the equalization tank, which plays a key role in stabilizing the flow and reducing undesirable odors. In the video, we showcase the operation of pre-aeration…
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 Aeration Stage in Dairy Wastewater Treatment
The aeration stage is a fundamental part of the biological wastewater treatment process in a dairy facility, as it facilitates the degradation of organic pollutants by aerobic microorganisms. Wastewater generated from dairy production contains high concentrations of organic matter, including proteins, fats, and lactose, all of which must be removed prior to discharge or water…
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…
