Pressure dissolved air flotation machine specifications and process composition
- Jun 29, 2018 -

Pressure dissolved air flotation machine refers to the purpose of dissolving air in water by pressurization, and then releasing micro-bubbles by decompression to adsorb suspended solids in water to achieve solid-liquid separation. In addition, this type of air floater also uses a mechanical scraping device. This kind of air flotation machine belongs to the air flotation equipment, and it is a kind of widely used air flotation equipment. It is suitable for all kinds of wastewater treatment, sludge concentration and water supply treatment, especially for wastewater treatment.


Pressure dissolved air flotation machines, if they are divided according to the amount of treated water, there are 5, 10, 20, 30, 40, 50, 75, 100, 125, 150, 200, 300 and 400 and other specification types, which are The model number is for QFJ.


The pressure dissolved air flotation process in the pressure dissolved air flotation machine consists of pressure dissolved air system, dissolved air release system and air floatation separation system.

Pressure dissolved gas system: mainly includes water pumps, air compressors, pressure dissolved gas tanks and some ancillary equipment. In the pressure dissolved gas tank gas supply, it is achieved through the air compressor.

Dissolved gas release system: It consists of two devices, the releaser and the dissolved gas line. The dissolved gas releaser releases gas from the water and quickly adheres to the impurities in the water.

Air flotation separation system: Generally, there are three kinds of advection, vertical flow, and integrated type, so that the micro-bubbles in the water are in full contact with the flocs, thereby realizing the separation of the air-entrained flocs and the clear water.
