--------------------------------Dissolved Air Floatation (Flat-flow type)

1. Description

YW series Dissolved Air Floatation is mainly for solid-liquid or liquid-liquid separation. Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or liquid particles with same density as waste water to make the whole float to the surface thus achieve the aim of solid-liquid or liquid-liquid separation.

2. Application

(1) Remove oil and TSS.

(2) Separate small particles and algae in groundwater.

(3) Recover valuable products in industrial sewage such as paper pulp.

(4) Act as secondary sedimentation tank to separate and concentrate suspended particles and sludge.

3. Features

(1) Large capacity, high efficiency and small occupying space.

(2) Compact structure, easy operation and maintenance.

(3) Silt expansion elimination.

(5) Aerate to the water while air floating, it has an obvious effect to the elimination of active agent and foul smell in water. Meanwhile, the increased dissolved oxygen provides a favorable condition to the follow-up process.

(6) It can achieve the best effect in adopting this method when disposing the water with lower temperature, lower turbidity and more algae.

4. Suitable area:

slaughtering, starch, pharmaceuticals, papermaking, printing and dyeing,

leather and tannery, petrochemical industry, domestic wastewater, etc.

Dissolved air flotation

Dissolved air flotation machine (DAF) is manufactured by our factory and mainly used for solid-liquid separation and liquid-liquid separation.

Work Principle:

The air will be send by air compressor into air tank, then take in air dissolved tank by jet flow device, the air will be force to dissolve into water under 0.35Mpa pressure and forming dissolved air water, then send to air flotation tank. Under the circumstance of sudden release, the air dissolved in water will be dissolve out and form vast microbubble group, which will be fully contact the flocculating suspended matter in sewage, the suspended matter was sent by pump and flocculation after adding medicine, the ascending microbubble group will adsorb in the flocculated suspended matter, made its density reduce and floated to water surface, thus reach the purpose of removing SS and CODcr etc.

Characteristics

1)Dissolved air pump edge bibulous the edge is inspiratory, pump pressurized mix within, gas to liquid efficient dissolving, small bubbles than 30 um.

2) Low voltage operation, the dissolved gas efficiency is as high as 99%, release rate as high as 99%.

3) Tiny bubbles and suspended particles of efficient adsorption, improve the SS remove effect.

4)Dissolved gas water dissolving efficiency 80-100%, than traditional dissolved gas floating high efficiency three times.

5) Pressure-capacity curve smooth, easy to achieve automatic control, easy to operate, easy maintenance, low noise.
