Wastewater Treatment Dissolved Air Flotation Systems (DAF)
Dissolved Air Flotation Systems (DAF) are indeed used in water treatment processes to remove suspended solids, oil, grease, and other contaminants from industrial wastewater. The process involves introducing air bubbles into the wastewater, which attach to the suspended particles and cause them to float to the surface, where they can be skimmed off and removed. This technology is widely used in various industries such as food processing, mining, oil and gas, and municipal wastewater treatment, among others, to achieve effective and efficient water purification.
Introduction
What is Dissolved Air Flotation Process
Purpose of Dissolved air flotation system: To remove suspended solids (SS), fats, oils, grease (FOG), and phosphorus (P) from industrial wastewaters effectively and economically.
Principle: Generation of micro bubbles through an air saturation vessel and air diffuser.
Chemical Process: Treatment chemicals are dosed upstream of the DAF inlet to form flocs, which interact with micro bubbles in the DAF chamber.
Separation Process: Micro bubbles attach to flocs, causing them to float to the top, where they are skimmed off by the top skimmer.
Effluent Discharge: Clean effluent is collected and discharged after the separation process.
Technology Innovation: Jorsun dissolved air flotation system combines traditional dissolved air flotation design theory with modern technology, developed after years of research and application.
Recycling: A portion of the effluent is recycled to the air saturation vessel to mix with air and form air dissolved water, contributing to the generation of micro bubbles.
Food Processing Wastewater: Wastewater generated from food processing industries often contains organic matter, fats, oils, and grease (FOG), which can be effectively removed using DAF systems.
Pulp and Paper Mill Effluents: Wastewater from pulp and paper mills contains suspended solids, fibers, and chemicals. DAF can help in the removal of these contaminants, improving water quality before discharge.
Textile Wastewater: Textile industries produce wastewater containing dyes, chemicals, and suspended solids. DAF systems can assist in separating these pollutants for cleaner discharge.
Oil and Gas Wastewater: Produced water from oil and gas operations can contain hydrocarbons, suspended solids, and other contaminants. DAF technology can be applied to treat this wastewater for reuse or safe disposal.
Mining and Metal Processing Wastewater: Effluents from mining activities and metal processing plants often contain heavy metals, suspended solids, and pollutants. DAF systems can aid in the removal of these substances, reducing environmental impact.
Chemical Manufacturing Wastewater: Wastewater generated from chemical manufacturing processes may contain various chemicals, solvents, and suspended solids. DAF can be utilized to treat such wastewater streams effectively.
Municipal Wastewater Treatment Plants: DAF systems are also used in municipal wastewater treatment plants to remove solids, oils, greases, and other contaminants before the treated water is discharged into water bodies or reused.
Pharmaceutical Wastewater: Pharmaceutical industries produce wastewater containing organic compounds, pharmaceutical residues, and solids. DAF can be employed to treat pharmaceutical wastewater and meet regulatory requirements.
