Dissolved Air Flotation Plant
Air floatation machine is a device to remove solid suspended matter, grease and various jelly in various industrial and municipal sewage. The equipment is widely used in the treatment of industrial wastewater and municipal wastewater such as oil refining, chemical industry,...
Send InquiryDissolved air flotation plant introduction
At present, there are many types of air floatation machines in the industry, including electrolytic air floatation, diffused air floatation, dissolved air floatation, combined air floatation, high-efficiency shallow air floatation and so on. Among them, the pressure-dissolving method of the advection pressurized dissolved air flotation machine is pressurized jet. This type of air flotation is widely used in China at present. The structure is relatively simple. The on-site operation and installation are relatively simple. Pretreatment and partial follow-up treatment of municipal wastewater.

Equipment characteristics
The dissolved air method of the vertical flow pressurized dissolved air floatation machine is pressurized jet. This type of air float has a complex structure, high height, and difficult operation and maintenance. It is relatively more effective than the horizontal flow pressurized dissolved air floatation. Great discounts only have an advantage in terms of floor space.
The multi-phase miscible air floatation machine uses a negative pressure suction in front of the pump. This type of air floatation is currently used more. Because it does not require air compressors and pressure vessels, it can basically replace the traditional For pressurized dissolved air flotation in the form of a machine, a dissolved gas tank, etc., a high-efficiency dissolved gas pump is generally selected.
The dissolved gas method of the high-efficiency shallow air floatation machine is pressurized jet. This type of air floatation is also widely used, especially in the paper industry, and other industries have begun to use it slowly in recent years. Due to the complex structure and relatively technical content High, suitable for projects with large water volume. It is recommended to use dissolved air flotation for water volume less than 100m³/hr.
