Product Description

 

High efficiency dissolved air flotation machine is mainly used for solid-liquid or liquid-liquid separation.  A large number of fine bubbles are generated in water through a dissolved and release gas system, in which the fine bubbles are adhered to solid or liquid particles in wastewater with similar density , so that the overall density of particles is less than that of water, and the fine bubbles are lifted to the water surface by buoyancy, thereby achieving solid-liquid or liquid-liquid separation.

Product Parameters

 
PARAMETERS:
 

Model	Water Volume (m³/h)	Length (mm)	Width (mm)	Hight (mm)
LQF -01	5	3600	1600	2000
LQF -02	15	5200	2000	2000
LQF -03	25	6800	2000	2500

WORKING PRINCIPLE:

The sewage is sent into the gas-liquid contact reaction area of the air flotation machine by the water inlet pump. In the gas-liquid contact reaction zone, the gas-liquid mixer will generate enough microbubbles to cause oil droplets, suspended solids and other pollutants in the water to adhere to the bubbles, and then bring the pollutants to the water surface in the separation zone to form scum.

The purified sewage overflows through the overflow weir and is discharged from the outlet pipe. The scum on the surface of the air flotation machine is scraped off the water surface by the slag scraper and enters the scum pool.

Then sent out by screw conveyor. Scum can be discharged through continuous scraping, but it is better to use intermittent scraping to reduce the moisture content of the scum, reduce the amount of scum, reduce interference with the water body, and stabilize the effluent quality.



ADVANTAGES:
  
Advantage 1 of the dissolved air flotation machine: short residence time, no backflow water and small footprint. During the flotation process of the dissolved air flotation machine, the hydraulic retention time is about 20~30 minutes.

Advantage 2 of the dissolved air flotation machine: simple structure, easy operation and maintenance. The main control parameter of the dissolved air flotation machine is the speed of the gas-liquid mixer. Its console can be installed indoors for centralized control, while the operation of the dissolved air system in dissolved air flotation is more complicated.

Dissolved air flotation machine has three advantages: low energy consumption and low investment. Compared with a device with a sewage treatment scale of 100m3/h, an air flotation machine generally only needs one gas-liquid mixer to meet the requirements, and its power is about 0.75kW. The dissolved gas and release system of a conventional pressure dissolved gas flotation cell generally consists of a return water pump, an air compressor, a dissolved gas tank, a dissolved gas release group and supporting pipelines. It not only has many static and dynamic equipment, but also requires high investment. And the energy consumption is also high.
