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

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

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

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

At the NIKZAS S.A. dairy facility, located in Makrychori, Larissa, a new, state-of-the-art secondary Biological Wastewater Treatment System was constructed, incorporating a Dissolved Air Flotation (DAF) unit. The project was designed, organized, and constructed by our company, tailored to the specific needs of NIKZAS S.A. We undertook the entire process—from

The aeration tank is a critical part of the process in biological wastewater treatment. It is the unit in which the biological degradation of organic compounds in wastewater takes place, with the help of aerobic microorganisms. The role of aeration is to provide the oxygen required for the growth and

Commencement of work on the installation of a new modern biological wastewater treatment plant in a cheese-making unit

The sedimentation function is an important mechanism in a biological wastewater treatment plant, which contributes to the separation and removal of solid particles and human waste from the liquid part of the wastewater. In the settling operation, the sewage enters a large tank or deep trench and is allowed to

The ventilation system is a critical element in biological wastewater treatment plants. The purpose of this system is to provide the necessary oxygen to the microorganisms present in the wastewater, in order to carry out the biological cleaning process. The aeration system usually consists of air ducts and various machines
