The effect of air flotation machine on removing solid suspended matter is remarkable. It mainly generates a large number of fine bubbles in the water, causing these bubbles to attach to the suspended particles and reduce their overall density, thereby using the buoyancy principle to make them float on the water surface and achieve solid-liquid separation. This process can effectively remove suspended solids in water, such as sludge, oil, etc.
Both experimental data and practical application cases show that the air flotation machine performs well in treating sewage containing different concentrations of suspended solids. Especially for the vortex concave air flotation machine, its effect in removing solid suspended matter is more obvious. Studies have shown that the removal rate of water quality indicators such as COD and BOD5 by the vortex air flotation machine is above 90%. At the same time, factors such as bubble size, water quality and water temperature may affect the removal effect of the vortex air flotation machine. For example, small bubbles can better adhere to the surface of solid suspended solids and improve the removal rate; while an increase in water temperature can effectively improve the removal rate of the vortex air flotation machine.
In addition, air flotation machines are not only used for industrial wastewater treatment, but are also widely used in drinking water treatment, oil-water separation, physical and chemical treatment, recovery of useful materials in sewage, and concentration treatment processes for residual sludge in sewage treatment plants.
