The automation system developed by FlotLife controls all critical parameters at each stage of the treatment process, such as flow volume, power consumption, pH, etc., allowing the equipment to be operated without the presence of the operator. Service personnel can only remotely connect to the system when needed to see the exact status of the wastewater treatment operations and, if
DAF is the best option for flotation water treatment in industrial water treatment stations. The thing which makes DAF units so fast and efficient and a water flotation technology is the high level of aeration brought to large volumes of wastewater in the device. Pollutants are removed very quickly. Wastewater which is cleaned now moves away from the flotation device and another step of
Primary wastewater treatments that remove these solids in process containers include primary clarifiers, air flotation units and cone shape Imhoff settlers.

Dissolved air flotation DAF is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.
