Dissolved Air Flotation Unit DAF Wastewater Treatment

Product Description

The technology of dissolved air flotation is widely used in drainage and waste water treatment, it can remove the frivolous floc which is difficult to precipitate in the waste water. It has the advantages of high processing capacity, high efficiency, small square, wide range of application, it is widely used in sewage treatment of petroleum, chemical industry, printing and dyeing, paper making, oil refining, leather, iron and steel, machining process, food, starch and so on.

Due to the loose requirements for flocculation conditions, the dosage of flocculant can be saved.

Application

The dissolved air flotation unit is widely used in sewage treatment of petroleum, chemical industry, printing and dyeing, paper making, oil refining, leather, iron and steel, machining process, food, starch and so on.

The dissolved air flotation unit DAF wastewater treatment is applied to the following aspects:

1. Separate the tiny suspended matter, algae and other microaggregates from surface water.

2. Recovery the useful substances from industrial waste water, such as paper pulp from the waste water.

3. Replace the separation of secondary sedimentation tank and concentration of sludge in the water.

Technological Process

The air flotation system integrates water inflow, flocculation, separation, water collection and effluent A stable flow chamber and dissolved gas release chamber make the treatment performance more stable and the effect is more superior.

1. Stabilization Room

The flow rate of raw water through folded plate reaction is very high, it will dissipate tiny bubbles, affect the effect of bubbles adhering to flocs, thus reducing air floatation treatment efficiency, if the steady flow chamber is added, the kinetic energy consumption of turbulent raw water will be uniform it can enter the dissolved air water release chamber quickly, thus effectively ensuring the removal effect.

2. Dissolved Air Release Chamber

The dissolved gas release chamber and the separation chamber are in a tank body. separated in the middle, dissolved air water and flocculation the finished raw water adheres here, rises slowly, and enters the air flotation separation chamber to ensure the contact space and time between floc and micro bubble make the release rate of dissolved air water reach 80-100%.

3. Dissolved Air System is The "Heart" of Air Flotation Equipment

For air flotation equipment, dissolved air system is just like air flotation equipment "heart" is also the most important part of the air flotation equipment, in this stage, the air with water in the pump inlet - start suction, shear pressure, mixed into dissolved air, water, gas the maximum gas content of the whole system is up to 10% and the solubility of the gas is 100%, which makes the micro bubble fraction of the gas disperse the average bubble diameter is less than 0um. the dissolved gas system 1s a kind of traditional gas flotation improvement and technological innovation have improved the separation efficiency of air flotation and greatly reduced the equipment production and operation costs.

4. Slag Scraper

The operation mode and speed of slag scraper directly affect the water quality and sludge of air flotation effluent solid content, the system adopts rotary slag scraper, which can connect scum with scum furthermore, the scum is scraped into the scum tank evenly to reduce the mutual collision of scum the scraper with adjustable degree can better adapt to various operating conditions equipment to reduce the moisture content of sludge.

5. Control System

The control system adopts advanced electrical components (delixi or chint) to ensure the equipment long term effective operation of.

Our Advantages

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

2. Compact structure, easy operation and maintenance.

3. Silt expansion elimination.

4. 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.

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