Introduction
The dissolved gas releasers find diverse applications in water and wastewater treatment across various industries, playing a crucial role in the removal of contaminants and the production of clean water for discharge or reuse. Their versatility and effectiveness make them valuable tools in achieving environmental compliance, resource conservation, and sustainable water management goals.
Working principle
Dissolved air flotation water purification method is to release the pressure-dissolved air water produced by the dissolved air system through the releaser to generate a large number of fine air bubbles and introduce them into the water to be treated. Utilize the buoyancy of bubbles adhering to solid impurities to achieve rapid separation of solid and liquid, and to improve the concentration of scum. Therefore, it is considered to be a major breakthrough in water treatment technology, and the dissolved air release device is the key device in the dissolved air flotation water purification system. The pressure-dissolved water can only release a large number of micro-bubbles after the device is depressurized and energy-dissipated. The performance of the releaser is related to the fineness of the bubbles, which directly affects the effect of air-flotation water purification.
Technical advantages
●Under the pressure of 3kgf/cm2, it can work effectively.
●The average diameter of released bubbles is 5-10 microns.
●The perfect degree of outgassing is above 99%.

Product Application
Here are some common applications of dissolved gas releasers:
Wastewater Treatment: Dissolved gas releasers are widely used in industrial and municipal wastewater treatment processes. In the DAF process, for example, air is dissolved under pressure into the wastewater, forming tiny bubbles that attach to suspended solids, oils, and other contaminants. These bubbles then float the contaminants to the surface, where they can be easily removed, resulting in clarified water.
Drinking Water Treatment: Dissolved Air release valves for water syste can also be applied in the treatment of drinking water. For instance, in the dissolved ozone flotation process, ozone gas is dissolved in water and then introduced into a flotation tank, where it helps in the removal of organic matter, color, and odor-causing compounds, leading to the production of high-quality drinking water.
Industrial Process Water Treatment: Various industries utilize dissolved gas releasers for the treatment of process water, such as cooling water systems, where the removal of suspended solids and organic matter is essential to maintain system efficiency and prevent equipment fouling.
Oil and Gas Industry: In the oil and gas sector, dissolved gas releasers are utilized for the treatment of produced water, which is water extracted along with oil and gas. Through processes like dissolved gas flotation, undesirable constituents such as oil and suspended solids are separated from the produced water, allowing for the recovery and reuse of water and the proper disposal of contaminants.
Mining and Mineral Processing: The mining industry uses dissolved gas releasers for the treatment of mining wastewater, which often contains high levels of suspended solids and metals. The flotation process involving dissolved gases aids in separating valuable minerals from the wastewater and in reducing the environmental impact of mining activities.
Food and Beverage Industry: Dissolved gas releasers are employed for the treatment of wastewater generated in food processing and beverage production facilities. By using flotation processes with dissolved gases, these industries can effectively remove organic matter, suspended solids, and fats, oils, and greases (FOG) from their wastewater streams.
Agricultural Wastewater Treatment: In agriculture, DAF Air water releasers can be used for the treatment of agricultural runoff and wastewater from animal husbandry operations. Flotation processes with dissolved gases help in removing nutrients, organic matter, and suspended solids, thereby mitigating the impact of agricultural activities on water quality.
