Package DAF system Product Overview
The Dissolved Air Flotation (DAF) system is a highly efficient solid-liquid separation equipment designed for industrial and municipal wastewater treatment. By generating a large number of micro-bubbles (20-50 microns) under pressure, the DAF system effectively attaches to suspended solids, oils, and greases in the water. This process reduces the density of the pollutants, causing them to float rapidly to the surface for removal, thereby achieving superior purification results. It is the ideal solution for wastewater where traditional sedimentation is ineffective.

Package DAF system Core Working Principle
Coagulation & Flocculation: Chemicals (coagulants and flocculants) are automatically dosed into the raw wastewater to form visible flocs (flocculation).
Dissolved Air Release: A portion of the treated effluent is recycled, pressurized, and saturated with air in the dissolved air tank. When released into the flotation tank, the pressure drop generates millions of micro-bubbles. Package DAF system
Solid-Liquid Separation: The micro-bubbles attach to the flocs, forming "bubble-particle" aggregates that float to the surface. A mechanical skimmer continuously removes the floating sludge, while clarified water is collected from the bottom.
Package DAF system Key Advantages
High Separation Efficiency: Capable of removing over 90% of Suspended Solids (TSS) and 80-90% of Fats, Oils, and Grease (FOG), significantly reducing COD/BOD loads.
Compact & Space-Saving: The integrated design (including reaction tank, flotation tank, and dissolved air system) requires a much smaller footprint compared to traditional sedimentation tanks.
Rapid Installation: Available in skid-mounted or containerized designs, the equipment is pre-assembled and tested at the factory, allowing for plug-and-play installation on-site.
Fully Automatic Operation: Equipped with a PLC control panel and automated dosing system, it supports unattended operation, reducing labor costs.
Versatile Applications: Suitable for a wide range of industries including food processing, slaughterhouses, paper mills, petrochemicals, and textile dyeing.
Typical Applications（Package DAF system）
Food & Beverage: Slaughterhouse wastewater, dairy processing, edible oil refining, and beverage production.
Pulp & Paper: White water recovery and fiber recycling.
Oil & Chemical: Refinery wastewater, oil-water separation, and petrochemical effluent treatment.
Municipal & Others: Algae removal in drinking water, sludge thickening in sewage plants, and landscape water purification.
Technical Specifications（Package DAF system）
(Note: Specifications can be customized based on specific influent water quality, such as high oil content or corrosive chemicals, and discharge standards.)
