Product Description
Dissolved air flotation units are a physical/chemical technology widely used in industrial and municipal wastewater treatment. DAF systems are often used to remove pollutants such as grease, suspended solids, etc. to meet different treatment goals, including product recovery and reuse, meeting sewer discharge limits, reducing the load on downstream biological treatment systems, polishing of biological treatment effluent, and enrichment of biosolids.

Working Principle
The working principle of dissolved air flotation units is based on the physical process of bubbles combining with suspended particles and floating to the surface of the water. First, gas (usually air) is injected into the water to form tiny bubbles. These bubbles combine with suspended particles and float to the surface of the water to form scum. This scum can be easily scraped or discharged, thereby achieving the separation and removal of solid particles.

Advantages
1. High efficiency. They are able to remove a wide range of contaminants from water, including grease, suspended solids, and organic compounds. This ensures that the water can be discharged safely and helps protect the environment from pollution.
2. Versatility. They can be used in a variety of different environments, from municipal wastewater treatment plants to industrial facilities. This makes them a valuable tool for any organization that needs to treat wastewater.
3. Easy to operate and maintain. They require minimal human intervention and can be automated to ensure reliable and consistent performance. This helps reduce operating costs and ensures the unit operates efficiently over the long term.
