Product Description
Steel mill dissolved air flotation is a physical and chemical process used to treat industrial wastewater. This treatment method works by dissolving air in water and then forming tiny bubbles when the pressure is released, causing suspended matter to float in the water and be removed. A DAF system usually consists of several main parts, including a gas injection device, a reaction tank, a clean water discharge system, and a solid matter collector.
Working Principle
The working principle of the DAF system is to use the buoyancy of air bubbles to separate suspended matter from water. When air bubbles come into contact with suspended matter, they adhere to the surface of the bubbles and float to the surface of the water together. Subsequently, these floating substances can be easily collected or discharged, thereby purifying the wastewater.
Advantages
1. Capable of removing oil, grease and heavy metals. This not only makes the water cleaner, but also helps reduce the environmental impact of steel mills and protect the health of nearby communities.
2. DAF is a cost-effective solution that takes up minimal space and can be easily integrated into existing wastewater treatment systems. It is also a low-maintenance, reliable method of treating large volumes of wastewater.
