The Latest Sewage Treatment Equipment—–Super Atomization Dissolved Air Flotation.

Super atomized dissolved air flotation is to release fine and dispersed micro-bubbles dissolved in water and adhere to organic matter, oil and suspended matter in sewage after adding chemical agents to become floating matter, so that organic matter, oil and suspended matter can be separated from sewage;

The first generation of dissolved gas air flotation is to pour water droplets into the air saturated tank, the particle size of the water droplets is several mm, and the air and water contact under pressure to achieve dissolved gas, and the dissolved gas efficiency and the dissolved gas effect are poor;

The second generation of dissolved gas air flotation uses jet tubes to inhale and disperse the air in the air saturated tank into the pressure water. The particle size of the air bubble is several mm, so as to achieve dissolved gas. The dissolved gas efficiency is slightly improved, but the dissolved gas efficiency and the dissolved gas effect are still poor, and the processing accuracy of the jet tube is very high.

The IEPP’s independent research and development of super atomization dissolved gas flotation technology belongs to the third generation of dissolved gas flotation technology, including super atomization dissolved gas technology, adjustable anti-blocking spin-mixed gas release technology, swirling flocculant technology, scraping slag concentration technology four core technologies, completely subdue the working principle of the second generation dissolved gas flotation, air flotation treatment effect is better, no blockage, stable and reliable operation. At present, it has been widely used in animal husbandry, slaughtering, oil, food and other high-slag (oil) wastewater treatment industry.

Working principle

IEPP’s self-developed super atomizing air flotation system has a unique atomizing jet device, and through the unique structural design inside the dissolved gas tank, the dissolved gas water forms a secondary high-speed impact, resulting in super-efficient dissolved gas effect, and can complete the entire dissolved gas reaction process within 0.6 seconds.

Scope of application

1. It is suitable for high-concentration sewage pretreatment, low-concentration sewage advanced treatment and purified water treatment where the proportion of suspended pollutants and colloidal pollutants is close to that of water. It is also suitable for sludge separation by sewage aerobic activated sludge method (instead of secondary sedimentation tank), and is not suitable for sewage treatment projects where the proportion of suspended pollutants and colloidal pollutants is too large.

2. Suitable for aquaculture, slaughtering, oil, paper, printing and dyeing, food, fermentation, oil refining, chemical, pharmaceutical and other industrial wastewater treatment, but also suitable for domestic sewage treatment.

Technological advantage

1. The gas dissolving device has high gas dissolving efficiency, good gas dissolving effect, no blockage, high gas release efficiency;

2. Small floor area, large processing capacity, high dissolving gas efficiency, power consumption saving, easy operation, simple management;

3. A large number of fine bubbles are produced in the water by the uniquely developed super atomized dissolved gas and rotary mixing cutting and releasing system. The diameter of the bubbles is below 40μm, so that hydrophilic organic matter and grease adhere to the surface of the bubbles and rise to the surface by buoyancy;

4. Air floating slag scraping system adopts new structural design, the system operation friction resistance is small, the number of scraper is sufficient, the slag scraping efficiency is high;

5. The unique structural design of the dissolved gas system makes the dissolved gas water form a secondary high-speed impact, resulting in ultra-efficient dissolved gas effect, and can complete the entire dissolved gas reaction process within 0.6 seconds;

6. The unique steady flow system in the air flotation device is designed to avoid the disturbance and destruction of the scum layer when scraping slag, so that the gas can not reach the ideal effect;

7. Oxygenating the water during operation has an obvious effect on removing surfactants and odors in the water, and provides favorable conditions for subsequent treatment due to the increase of dissolved oxygen in the water;

8. The super-atomized air flotation device has a high removal rate in the pretreatment stage of aquaculture, slaughtering, grease and other sewage, and the removal rate of grease, suspended matter and insoluble COD can reach more than 90%, which simplifies the selection and design load of the follow-up treatment process, reduces the volume of the follow-up treatment system, and reduces the equipment, civil construction investment cost and operating cost;

9. The new type of rotary mixing cutting release is not easy to plug, and the efficiency of the release is more than 99%.
