High-efficiency shallow air flotation machine is the use of small bubbles or tiny bubbles to make the impurities in the medium float out of the water surface machine.
In the water supply and drainage treatment process program, solid and liquid separation technology and its equipment is one of the key processes.
For the specific gravity close to the water of the tiny suspended particles to go, air flotation is the most effective method. This equipment is designed by successfully applying "shallow pool theory" and "zero speed" principle, and it integrates flocculation, air flotation, slag skimming, sedimentation and mud
scraping, which is a kind of high-efficiency and energy-saving water purification equipment and is widely used in water supply and drainage treatment projects.
The main structure of the shallow air flotation machine: the main machine of the high-efficiency shallow air flotation equipment refers to the separation part of the air flotation equipment, which includes: the pool body, the scum collection device, the overflow adjustment device, the rotating water inlet and water distribution mechanism.
The use of zero-speed principle - water from the center of the pool into the water, water pipe clockwise rotation, the water from the pipe reverse spray; water relative to the pool wall speed close to zero speed, no stirring of the water in the pool, so that the particles in the water in the static upward or settlement, high degree of purification, the removal rate of suspended solids up to 90% or more.
Utilizing the shallow pool theory - the water depth is typically 600-700mm - the uplift path is short, low resistance and fast.
Utilizing the theory of dissolved air - the use of higher pressure dissolved air tube, unit dissolved air efficiency is high, up to 90%, air flotation effect is good.
