 seated aeration machine for water treatment

1. Work principle
This aeration machine consists of submersible pump, jet device, scattered flow device, the suction and hose five parts as shown in the diagram below. Based on the traditional jet mechanism of shirt-sleeve advanced scattered flow technology, using jet aeration way.

Runtime, pump impeller in submersible motor driven by high speed rotating, will push the jet device facade mixture formed around the jet, the jet negative pressure produced area, will air through the suction nozzle negative pressure area, inhaled jet in jet device in the pipes of gas, water and mud, and fully mixing is spread by jet the kinetic energy of jet gradually transform into pressure can enter scattered flow device. In scattered flow containers, gas, water, mud mixture, forcing gas continue to further blended shear, crushing and emulsification, guarantee most of the oxygen dissolves in water. Meanwhile, in jet under the effect of fluid pressure, jet carrying oxygen molecules and tiny bubbles, from the scattered flow of the nozzle tilted down is out of water, forming, diffusion and the impact of biochemical sludge, stirring bottom bottom, after rising to the surface by slowly, tiny bubbles in the water retention time for 30 seconds or above average, make the oxygen in air is fully dissolved and absorption, improve the oxygen transfer efficiency and oxygen-rich ability.

This equipment can make sturry the jet device with air produced inside higher suction pressure and strong turbulence, mixing, shear, prompting liquid membrane and gas membrane high frequency oscillation, make the bubble diameter reduced substantially, the bubble, increase the number of bubbles more than surface area, also contentious liquid film thinning, can greatly reduce mass transfer resistance, make oxygen from the air better phase transfer to liquid.

Jet in high speed progress within the distributor, in the role of high-speed, high velocity, make jet with strong penetration, the tiny bubbles in the water, enhance stirring, travel far pushing flow and increasing oxygen ability.

2. High dissolved oxygen
Unique design, make scattered flow device with the air inhaled facade mix evenly, have a bubble small and numerous, dissolved oxygen rate is high. Oxygen transfer efficiency as high as 30%, than traditional drum wind aeration improve 35%.

3.Stir fully.
High speed rotating gas, water and mud mixture (i.e. activated sludge) strong penetration, make the oxygen in water transfer efficiency high, and achieve good mixing effect, can ensure the mixing of activated sludge remained active sludge, a suspended state. At the same time, because of tyre mixing flow, improving the function strong capacity utilization of aeration.
