Experience unmatched efficiency with our state-of-the-art High Efficiency Dissolved Air Flotation Machine, meticulously engineered for both solid-liquid and liquid-liquid separation. This cutting-edge technology generates a multitude of fine bubbles through an advanced dissolved and release gas system. These incredibly fine bubbles adhere to solid or liquid particles within the wastewater, even those with similar densities, effectively reducing their overall density below that of the water. Subsequently, these particles buoyantly rise to the surface, ensuring precise and effective separation. Elevate your wastewater treatment process with this innovative solution.

MECHANISM OF OPERATION:
The wastewater is directed into the gas-liquid contact reaction zone of the air flotation machine via the inlet pump. Within this zone, the gas-liquid mixer produces ample microbubbles that attract oil droplets, suspended solids, and other pollutants. These pollutants adhere to the microbubbles and are carried to the surface in the separation zone, forming scum.
The clarified water then overflows through an overflow weir and exits via the outlet pipe. Simultaneously, the surface scum is scraped off by a slag scraper and directed into the scum pool.
Subsequently, the scum is transported by a screw conveyor. While continuous scraping is possible, intermittent scraping is recommended to lower the scum's moisture content, reduce its volume, minimize water interference, and enhance effluent quality stability.
KEY ADVANTAGES:
Advantage One of the dissolved air flotation machine: features a short residence time, no backflow water, and a compact footprint. The hydraulic retention time during the flotation process is approximately 20 to 30 minutes.
Advantage Two of the dissolved air flotation machine: boasts a simple structure, with easy operation and maintenance. The main control parameter is the speed of the gas-liquid mixer, which can be managed from an indoor console for centralized control. However, the operation of the dissolved air system is more complex.
Dissolved air flotation machine features three key advantages: low energy consumption and minimal investment. Compared to other systems with a treatment capacity of 100m³/h, the air flotation machine typically requires only a single gas-liquid mixer, operating at about 0.75kW. Conventional systems, with many static and dynamic components, demand higher investments and energy consumption, as they include a return water pump, air compressor, dissolved gas tank, release group, and extensive pipelines.
