Stainless Steel DAF Standard Air Flotation Machine 2 - 150 m3/h

Air flotation work and system principle.
Air flotation separation is the air and water under certain pressure and conditions, so that the gas is dissolved into the water to a great extent, and strive to be in a saturated state, and then the formation of pressure dissolved gas water through a special device to release the pressure, the rapid production of a large number of micro-bubbles, and the water is the floating material (after the addition of flocs) in full contact with the purple particles of the "net catch", "wrapping", "bridging" effect, bubbles and is the floating material to form a stable entrained gas floc, the density of which is less than that of the water. In the purple particles of the "net catch", "wrapping", "bridge" role, the bubbles and is floating to form a stable air-filled floc, its density is less than water, so the air-filled cai body quickly rose to the surface, is floating in the liquid surface agglomeration of slag, slag scraping, removal that is, to achieve the separation of solid-liquid The purpose of solid-liquid separation. The effect of solid-liquid separation depends mainly on the following three aspects.
1, the characteristics of floc formation after dosing in the water body is hydrophilic or hydrophobic (appropriate dosing). 2, the mixing reaction, to ensure that there are enough micro-bubbles in time to fully contact with flocs
3, separation reaction, solid, gas, liquid mixture should have appropriate residence time and smooth flow pattern, so that the "entrapped flocs" float to the liquid surface, forming scum. Control of liquid flow is one of the keys to the separation effect.

Air flotation Machine applicable to industry fields.

1, industrial wastewater pretreatment: food processing, pharmaceuticals, textile printing and dyeing, semiconductors, machinery, steel, chemical industry, aquaculture and other industries wastewater

2, sewage treatment plant: sewage pretreatment, upgrading, phosphorus removal

3,Water treatment plant: algae removal

4,Ecology: river, lake purification, landscape water treatment

5,Desalination project

Features and advantages.

Overall complete set, compact structure, cost-effective market retention, high maturity, stable performance, reliable operation

Hydraulic load: 4~6m3/(m2.h)

The allowable concentration of floating matter can be up to 3000mg/L.

Floaters can realize automatic skimming, the solid content can be as high as 30~100g/L applied to solid flocs density is generally lighter than water or close to water, precipitation phenomenon is weak water quality.
