Discover unparalleled efficiency with our High Efficiency Dissolved Air Flotation Machine, expertly engineered for both solid-liquid and liquid-liquid separation. This state-of-the-art system generates a multitude of fine bubbles through an advanced dissolved and release gas system. These bubbles adhere to solid or liquid particles in wastewater, transforming their density to be lighter than water. As a result, particles are effortlessly lifted to the water surface by buoyancy, achieving exceptional separation. Experience cutting-edge technology that ensures clean and clear water with every use.

WORKING PRINCIPLE:
The sewage is introduced into the gas-liquid contact reaction area of the air flotation machine by the water inlet pump. Within this zone, the gas-liquid mixer produces abundant microbubbles that attract oil droplets, suspended solids, and other contaminants. These pollutants adhere to the microbubbles and are subsequently lifted to the water surface in the separation zone, forming scum.
The clarified sewage then overflows through the weir and exits via the outlet pipe. The surface scum is efficiently scraped off by the slag scraper and directed into the scum pool.
The collected scum is transported away by a screw conveyor. Continuous scraping can remove scum, but intermittent scraping is preferred to lower the moisture content of the scum, reduce its volume, minimize interference with the water, and stabilize effluent quality.
ADVANTAGES:
Advantage 1 of the dissolved air flotation machine: It offers a short residence time, eliminates the need for backflow water, and requires a small footprint. The hydraulic retention time during the flotation process is approximately 20 to 30 minutes.
Advantage 2 of the dissolved air flotation machine: It boasts a simple structure, making it easy to operate and maintain. The crucial control parameter is the speed of the gas-liquid mixer. The control console can be housed indoors for centralized management, although the operation of the dissolved air system itself is more complex.
Dissolved air flotation machine has three distinct advantages: low energy consumption and minimal investment. For a sewage treatment scale of 100m³/h, typically one gas-liquid mixer suffices with a power requirement of about 0.75kW. In contrast, traditional pressure dissolved gas flotation systems require a return water pump, air compressor, dissolved gas tank, dissolved gas release group, and supporting pipelines, involving numerous static and dynamic equipment, leading to higher investment and energy consumption.
