BENENV Dissolved Air Flotation (DAF) System: Advanced Water Treatment Solution
The BENENV DAF system employs cutting-edge physical separation technology to effectively remove suspended solids, oils, and other contaminants from wastewater through microbubble adsorption, achieving superior water purification.
Working Principle of BENENV DAF System:
Pressurized Aeration Stage: BENENV's patented aeration device fully dissolves compressed air into partial recycled water.
Pressure Release Stage: The aerated water is instantaneously released into the atmospheric flotation tank, generating fine microbubbles (20-50μm).
Bubble Adhesion Stage: Microbubbles physically adsorb onto contaminants.
Floating Separation Stage: Bubble-contaminant complexes rapidly ascend to the water surface.
Sludge Removal Stage: BENENV's automatic scraper system precisely removes surface scum.
Treated Water Collection Stage: Purified water is discharged through the bottom collection system.
Our DAF (Dissolved Air Flotation) equipment distinguishes itself through remarkable efficiency in contaminant separation, along with exceptional durability and reliability. We offer a diverse range of dissolved air flotation systems, capable of treating wastewater volumes ranging from 5 cubic meters per hour to 1,000 cubic meters per hour.
Dissolved air flotation stands as the most efficient technology for eliminating major pollutants in wastewater, including:
·Suspended Solids (TSS): Particulate matter that remains undissolved in water.
·Oils and Fats: Lipid-based substances that form floating layers or emulsions.
·Reduction of Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD): Organic and inorganic compounds that consume oxygen during decomposition, measured by BOD (biological oxidation) and COD (chemical oxidation).
·Algae and Total Carbon in Seawater for Desalination Plants: Organic matter and microorganisms that can interfere with desalination processes.
·Other Contaminants: Nutrients (e.g., nitrogen, phosphorus), detergents, heavy metals, and more, which may require specialized treatment depending on their composition.
Why DAF Unit Is Effective for Contaminant Removal
Rapid Separation: DAF typically takes 10–30 minutes, much faster than sedimentation (hours).
Removal of Low-Density Particles: Efficiently captures oils, fats, and fine solids that are difficult to settle.
Flexibility: Adjustable through chemical dosing and operational parameters to handle varying wastewater types.
Technical Advantages of BENENV DAF:
Exceptional treatment efficiency: ≥95% SS removal rate, ≥90% oil removal rate
Cost-effective operation: 30%+ lower energy consumption than conventional processes
Space-saving design: Modular configuration reduces footprint by 40%
High automation: Integrated with BENENV intelligent control system
High sludge concentration: Scum with 3-5% solid content achievable
