Air Flotation Equipment Sewage Treatment
Description Of The DAF Machine
DAF machine mainly made up of dissolved air flotation system , scraper system and electric control
1) Dissolved air flotation system : Feeding the clean water into dissolved air tank by the backflow pump from the clean water tank. Meantime,air compressor press the air to the dissolved air tank . Release to inside of the tank after mixing air and water by the releaser
2) Scraper system :scrape the scum floating on the water into the scum tank
3) Electrical Control : The electrical control make the DAF machine reach the best effect
Application
The flotation machine can be used as followed:
1)Separate the tiny suspending matter and algae from the surface water
2)Retrieve useful matter from the industrial waste water. For example the pulp
3)Instead of the second sedimentation tank separation and sludge of concentrate water
Working 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 COD etc. -

DAF sedimentation tank – flotation system Industrial Waste Water Treatment Equipment
Description:
Dissolved Air Floatation Machine is mainly used for solid-liquid or liquid-liquid separation. Large sum of micro bubbles
produced by dissolving and releasing system adhere to solid or liquid particles which with the same density as waste water to moke
the whole float to the surface thus achieve the goal of separation. -
Palm oil screw press
Multi-Disk Screw Press( Hereinafter referred as MDS ) belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

Solid liquid separation for wastewater treatment
Features
1 Small footprint, Low energy consumption; Easy operation; Simple management;
2 Efficient dissolved air; Stable treatment effect ; Full-automatic operation;
3 HB Type Dissolved Air Systerm is used in this device. It has ingenious structure, and its efficiency of dissolving air is as high as 90%. But its volume is only one-fifth of the other kind of dissolved air system. In addition, it still has the super anti-clogging ability which is incomparable;
4 Release effect and the mean diameter of microbubble is only between 15 to 30 microns. In addition that,this kind of dissolved air releasers also has the self-cleaning ability;
5 This device also applies HB Type Chained Scum Skimmer, works Smooth and reliably and skims scum efficiently.

High-Efficient Dissolved Air Flotation System
Dissolved air flotation is one of the most effective methods whose specific gravity is close to 1.0 from water.Dissolved Air Flotation is liquid/solid or liquid/liquid separation process to remove tiny suspended solids that density close to the water, colloid , oil and grease etc. Benenv dissolved air flotation is an innovation combined with traditional dissolved air flotation concept and modern technology.

Rotary drum thickener
The semi-centrifugal rotary drum thickener can filter the free water by means of external force. It has high requirements for the polymer and the binding force of sludge. In comparison with the belt thickening machine, our rotary drum sludge thickener can offer the thickened sludge with lower water content. The sludge with its water content of over 1.5% is a better choice.

Polymer preparation unit
Our automatic polymer preparation unit is one of the indispensable machines within this industry for the preparation and dosing of the flocculating agent. Flocculation is considered as the most necessary and economically feasible method to separate the suspended particles from the liquid. Therefore, flocculating agents are commonly used in all kinds of water treatment industries. With many years of successful experience in water treatment industries, HaiBar has developed the HPL series dry-po... -
Volute Sludge Dehydrator
Working Procedure for volute sludge dewatering ① Through the sludge pump, sludge to be delivered to the sludge conveyor port ② Sludge to be transported to the flocculation box after adjusting the flow by metering tank ③ After the mixing to form a large alum flowers, it will be sent to the screw body ④ The alum flowers do the gravity concentration while move to the dehydration part ⑤ The space between fixing and moving plates becomes smaller and smaller, and dewaters again by adjusting outle... -
Multi Disk Sludge Dehydrator
The dewatering body is formed by a screw axis with fixing and moving plates overlapping, as the inner diameter of screw axis is larger than the moving plate, the moving plate do the circular motion with the screw axis to prevent clogging. The space between the fixing and moving plates becomes smaller and smaller along the direction of mud discharge. After gravity concentration, the sludge is transported to the dehydration parts, it dewaters under the inner pressure of outlet back plate. -
