Product Overview:
The 70m³/h 304 Stainless Steel Dissolved Air Flotation (DAF) Machine is a high-efficiency system designed for removing suspended solids (SS), reducing COD, BOD, chromaticity, and other pollutants from industrial sewage. Constructed entirely from corrosion-resistant 304 stainless steel, this unit ensures durability and long-term performance in demanding environments.
System Composition:
The DAF system integrates the following key components:
Air flotation tank
Dissolved air system
Recirculation water pipeline
Dissolved air water release device
Skimmer mechanism
Advanced electrical control system
This compact, modular design minimizes footprint, simplifies installation, and facilitates maintenance.
Working Principle:
Coagulant and flocculant are dosed into the influent water. After sufficient flocculation time, the pretreated water enters the contact zone, where it mixes with micron-sized air bubbles from the dissolved air water. These bubbles attach to the flocs, forming a bubble-floc aggregate that rapidly rises to the surface in the separation zone. The buoyant force of the bubbles separates the suspended solids, forming a floating sludge layer. A skimmer continuously removes the sludge, while clarified water is collected from the bottom via a perforated collection pipe. A portion of this clean water is recycled to the dissolved air system, and the rest is discharged as treated effluent.
Applications:
This system is widely used in:
Removal of algae and turbidity from surface water (rivers, lakes) for potable or landscape water use
Pretreatment of domestic sewage and sludge thickening
Recovery of fibers and recycling of white water in paper mills
Removal of color and impurities in textile dyeing wastewater
Precipitation of heavy metal ions in electroplating wastewater
Oil-water separation in refinery wastewater
Solid-liquid separation in tannery wastewater
Treatment of industrial effluents from chemical, food processing, wool scouring, slaughterhouses, breweries, mining, and washing operations
Technical Advantages:
Compact Integrated Design: Pre-assembled modules reduce space requirements, simplify transportation, and enable quick installation.
Automated Operation: User-friendly PLC control ensures easy operation and reduced manual oversight.
High-Efficiency Dissolved Air System: Adjustable air dissolution pressure and recirculation ratio allow stable performance under variable loads.
Flexible Configuration: Available with single or dual dissolved air systems to suit specific water quality needs.
Efficient Release Mechanism: The specialized释放器 (release device) maximizes bubble formation and utilization.
Low-Noise Operation: Equipped with silent air compressors to minimize environmental noise.
Standardized Components: All parts are commonly available, simplifying maintenance and reducing downtime.
