Dissolved Air Floatation System (DAF)
Supplying dissolved air flotation (DAF) units for industrial wastewater treatment. Our equipment stands out for its efficiency and durability and can treat from 5 m3/hour to 1000 m3/hour of wastewater.
Description:
Dissolved Air Flotation (DAF) is a widely used method for the removal of suspended solids, oils, and grease from wastewater. Here's how it typically works:
- Saturation: Air is dissolved into the wastewater under pressure. This is usually achieved using a specialized pump or saturator.
- Release: The pressure is rapidly reduced as the wastewater enters the flotation tank, causing the dissolved air to form tiny bubbles.
- Attachment: The bubbles attach to the suspended solids, oils, and grease particles in the wastewater, forming aggregates that have a lower density than water.
- Floatation: The buoyant aggregates rise to the surface of the flotation tank, forming a layer of froth or sludge known as the float.
- Skimming: A skimming mechanism removes the float from the surface of the tank, separating it from the treated water.
- Effluent Discharge: The treated water, now largely free of suspended solids, oils, and grease, is discharged from the bottom of the tank or further treated if necessary.
DAF systems are effective in removing a wide range of contaminants and are commonly used in industries such as food processing, pulp and paper manufacturing, oil refining, and municipal wastewater treatment plants. They offer advantages such as high efficiency, low energy consumption, and ease of operation and maintenance. Additionally, DAF systems can be customized with various features and configurations to suit specific wastewater treatment needs.
Dissolved Air Flotation (DAF) systems are versatile and find applications in various industries and scenarios where the removal of suspended solids, fats, oils, and grease from wastewater is required.
These applications demonstrate the effectiveness and versatility of DAF systems in various industries and wastewater treatment scenarios, contributing to environmental protection and sustainable water management practices.
Here are some common applications of DAF systems:
