Air flotation machine

Air flotation machine is a water treatment equipment that generates a large number of micro bubbles in the water by the dissolved air system, causing air to adhere to suspended particles in the form of highly dispersed micro bubbles, resulting in a density less than water. It uses the principle of buoyancy to float on the water surface, thus achieving solid-liquid separation. Air flotation machines are divided into super efficient shallow air flotation machines, concave air flotation machines, and horizontal flow air flotation machines. It has applications in water supply, industrial wastewater, and urban sewage treatment. The advantage of an air flotation machine lies in its solid-liquid separation equipment, which has the characteristics of low investment, small floor area, high degree of automation, and convenient operation and management.

Air flotation machine is a machine that uses small bubbles or small bubbles to surface impurities in the medium. This air flotation device can be used for small particles with a specific gravity close to that of water, which are difficult to sink or float due to their own weight.

In terms of water supply and drainage, the pre-treatment water quality, except for some raw water bodies with high sand content and sewage with heavy mechanical impurities, is mostly composed of lightweight suspended particles. For example, algae in lakes, reservoirs, and some rivers; Plant residues and small colloidal impurities; Dye particles in the printing and dyeing industry; Short fibers in the papermaking and chemical fiber industries; Microdroplets of petroleum and organic solvents in the refining and chemical industries; Heavy metal ions in electroplating and pickling wastewater; Electrophoretic paint wastewater, etc; They are lightweight particles with a specific gravity very close to that of water. For these raw water, if traditional sedimentation methods are used, the effect will inevitably be poor, especially in low temperature winter conditions, where coagulation and hydraulic conditions deteriorate, making it more difficult to ensure the treatment effect. It can be imagined that if it is difficult to settle flocs, forcing them to sink will inevitably result in half the effort. Instead, it is better to use the situation to artificially introduce bubbles into the water body, making them adhere to the flocs, thereby greatly reducing the overall density of the flocs, and using the speed of bubble rise to force them to float up, thus achieving rapid solid-liquid separation. In this sense, the emergence of air flotation technology is a revolution in the gravity sedimentation method, which has opened up new fields of solid-liquid separation technology.

Purpose of air flotation machine:

OLTE air flotation machine is a device for removing solid suspended solids, fats, and various colloidal substances from various industrial and municipal wastewater. This equipment is widely used for the treatment of industrial wastewater and municipal wastewater in oil refining, chemical engineering, brewing, vegetable oil production and refining, slaughtering, electroplating, printing and dyeing, etc.
