1. As a result of the new technology structure of rotating distribution and catchment of water, water is basically in a static state inside the tank, the suspended particles will rise up efficiently in vertically trend without interference.
2. In the new equipment, the distributing flow has no interference in the water flow while the traditional one does, additionally the floating condition is better. Thereby the depth of the tank is substantially reduced.
According to the design manual of the traditional flotation system, the required depth is 2-2.5 m, however, the shallow tank flotation only needs 0.4-0.5 m. Resulting from the smaller distance of flotation, so the efficiency of solid-liquid is increased significantly.
3. Base on the higher efficient of airflotation, the detention time of water inside tank is shortened from the traditional approx. one hour to about 4-6 minutes now, which helps enhance the treatment rate of 10-15 times.
4. The shallow tank flotation devices is a integration of reaction, air and deposition, not only remove the micro suspended materials in the water, but also remove greater density particles.
5. Since the water in tank is basically in a static state, thus it can remove the suspended solids efficiently. Rotating water collecting pipe is lag behind in the tank to avoid the situation in traditional system, where some of heavier particles enter into the collecting pipe in the fixed bottom of the tank with the flow during their setting. Thus the effluent quality is better than the traditional flotation.
6. Compared with the traditional airflotaion, the shallow flotation system can save flocculant 10-20%. For the hydroentanglement process circulating water, the removal rate of fiber is up to 85-95%.
7. Thanks to the shallow tank, the required pump lifts is lower( for conditional water can be self-flow) and the necessary flocculant is also small, thus the operating cost is lower than traditional flotation.
8. Shallow tank is thin and light in weight, you can stack several tank arrangement, also can be placed on the floor or roof, it’s available for small area installing water treatment facilities. In a follow-up process, water treatment facilities can be installed above on the follow-up equipment for saving area.
9. For sewage treatment, airflotation system can increase the dissolved oxygen in the water, and improve the water quality.
10. The price of shallow tank flotation devices is significantly lower than the traditional devices, on the other side, it’s easy to operate and observe the operation.
