Dissolved Air Flotation (DAF) Systems - The Ultimate Solution For Water Treatment 

Dissolved Air Flotation (DAF) systems have become an essential component in the water treatment industry. They are designed to remove pollutants, such as suspended solids, oils, and grease, from wastewater, industrial process water, and other contaminated water sources. The primary objective of DAF systems is to provide high-quality treated water that can be reused or discharged safely into the environment.

The Working Principle Of DAF Systems

DAF systems work by creating tiny air bubbles that attach themselves to suspended pollutants in the water. The bubbles lift the pollutants to the surface, where they can be easily removed. The process starts with the addition of a chemical coagulant to the water, which causes the suspended particles to clump together. This makes it easier for the air bubbles to attach to the particles and lift them to the surface.

Once the pollutants have been lifted to the surface, they are removed by a skimming device. The cleaned water is then ready for discharge or reuse. The process is repeated continuously to ensure that the water remains free of contaminants.

The Benefits Of Using DAF Systems

There are numerous benefits to using DAF systems for water treatment. These include:

  • High efficiency

    DAF systems are highly effective in removing a wide range of pollutants from water. They are capable of removing up to 95% of suspended solids, oils, and grease from water.

  • Cost-effective

    DAF systems are more cost-effective than other water treatment methods, such as chemical precipitation and sedimentation. They are also more energy-efficient, as they use less energy to create the air bubbles than other methods.

  • Easy to maintain

    DAF systems are simple to maintain and require minimal operational attention. They are also easy to operate, making them ideal for use in remote locations where maintenance and repair services may not be readily available.

  • Environmentally friendly

    DAF systems are environmentally friendly, as they do not produce any harmful by-products or discharge pollutants into the environment.
