Dissolved Air Flotation

الوصف

Dissolved air flotation is a process technology device that implements solid-liquid separation or liquid-liquid separation. It is mainly used to separate and remove substances such as suspended solids, colloids, oil or grease, algae, etc., in water that have a density close to or less than water.
Air flotation is a process technology device to achieve solid-liquid separation or liquid-liquid separation. It is mainly used to separate and remove suspended matter, colloid, oil or grease, algae and other substances in water with density close to or smaller than water.
According to Henry`s law, through the dissolution and release process of dissolved air flotation, the device can produce a huge amount of microbubbles with a particle size of 3~*0μm in water. After water or wastewater undergoes coagulation or flocculation, suspended solids or colloids in water form large flocs. After entering the device, large flocs are fully mixed and contacted with microbubbles, adhere to microbubbles to form a floating body with a density smaller than water, float to the surface of the water, and are removed by a scraper machine to achieve solid-liquid separation and purify water quality.
