Introduction
High-speed ion flotation mainly introduces a large number of tiny bubbles into the water, so that pollutants such as suspended matter and colloids in the water adhere to the bubbles, forming a floating body with a specific gravity less than that of water, which floats to the water surface and is removed. Its uniqueness lies in the use of a high-speed ion generator to generate a large number of charged ions. On the one hand, these ions can neutralize the charge of pollutants in the water, making it easier to combine with bubbles; on the other hand, they can change the surface tension of water and promote the formation and stability of bubbles.

Structure And Working Process
Super efficient shallow air flotation machine equipment is composed of air flotation tank, dissolved air system, dissolved air water return pipeline, dissolved air water release device, scraper and electronic control system.
Air flotation mainly plays the role of solid-liquid separation (at the same time it can reduce COD, BOD, chromaticity, etc.). Coagulant and flocculant are added to the raw water. After the effective flocculation reaction time, the raw water enters the combined air flotation contact zone. In the contact zone, the microbubbles in the dissolved air water and the flocs in the raw water adhere to each other and enter the separation zone together. Under the buoyancy of the bubbles, the flocs and bubbles rise to the liquid surface together to form scum. The scum is hung to the sludge area by the scraper. The clean water in the lower layer flows to the clean water tank through the water collection pipe. Part of the clean water flows back for use in the dissolved air system, and the other part is discharged.
The refluxed clean water passes through the jet suction device, and under a certain working pressure, the air is dissolved into the water to the maximum extent, becoming dissolved air water. The dissolved air water is released in the contact area of the flotation tank through the rapid decompression of the release device, forming microbubbles with a diameter of 5-10μm. The microbubbles can bond with the flocs in the raw water.
Technical advantages
The shallow air flotation machine system adopts an integrated combination method, which effectively reduces space requirements, occupies a small area, has low energy consumption, and is easy to install and transport.
It has a high degree of automation, is easy to operate, and is simple to manage.
The dissolved air efficiency is high, the treatment effect is stable, and the dissolved air pressure and dissolved air water reflux ratio can be adjusted according to needs.
According to different water quality and process requirements: a single dissolved air device or a double dissolved air device can be provided.
High speed ion flotation uses an efficient releaser to improve the utilization efficiency of dissolved air water and ensure the stability of the flotation equipment.
The low-noise compressor is used to solve the noise problem that has plagued people for a long time.
The high speed flotation system adopts standardized configuration, and any accessory can generally be purchased locally or commissioned for processing.
