Product Description

Oil Water Sepatator, Sewage Treatment Machine, Daf Dissolved Air Flotation




 

1. Introduction
Dissolved air flotation machine (DAF) is manufactured by our factory and mainly used for solid-liquid separation and liquid-liquid separation. Flotation device will produce large amounts of tiny bubbles by dissolved gas and release system in the water, to make the adhesion in the waste water and water close to the density of solid or liquid particles, causing the whole condition of density smaller than water, and depend on the ascend to the surface flotage, so as to achieve the purpose of the liquid-solid separation, liquid-liquid separation.

2. Main effect:
Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including:
2.1.Product recovery and reuse
2.2.Pretreatment to meet sewer discharge limits
2.3.Pretreatment to reduce loading on downstream biological treatment systems
2.4.Polishing of biological treatment effluent
2.5.Thickening of biosolids
2.6.Product recovery and reuse Pretreatment to meet sewer discharge limits 
2.7.Pretreatment to reduce loading on downstream biological treatment systems Polishing of biological treatment effluent ,thickening of biosolids   

3. Main Structure
3.1  Air flotation machine:steel structure, it is the main body and core of DAF, which inside is composed of releaser,uniform distribution device,sewage pipe,outlet pipe,sludge tank and scraper system etc.
Releaser set in the central of air flotation machine, it is the key parts of producing microbubbles. The dissolved air water from dissolved air tank is fully mixed sewage in here, suddenly release, producing vigorous agitation and vortex, then form diameter 20-50UM microbubbles, it adhere to flocculating constituent in sewage, thus reduce the flocculating constituent proportion and ascend, cleaning water will be separated out thoroughly. Outlet pipe uniform distribution the bottom,and via 1pc erect main pipe connect to top overflow, overflow exit equipped with water level regulating handle, convenient to adjust water level in tank,. Discharge pipe install in bottom of tank, used to discharge sediment deposit in tank bottom.  The tank body equip with sludge tank, the scraper set in the sludge tank, the scraper rotation constant, continuous scrape the floated sludge into sludge tank, then flow automatically into sludge pond.
3.2 Dissolved air system is mainly composed of dissolved air tank, air storage tank, air compressor and high pressure pump, dissolved tank is the critical parts of system, its function is realize water and air fully contact , speed up air dissolve, which is a closeness Withstand Voltage steel tank, its inside equip with baffle plate,sleeve, to speed up air and water speed, improve  dissolved air efficiency.
3.3 Grouped equipment for DAF machine
 Chemical dosing system : metering pump, mixing motor, PE tank .add PAC PAM liquid to wastewater.
 Pipeline flocculator : Make sure PAM PAC liquid with wastewater mixed enoughly

4. Work Principle of DAF machine
4.1. Add flocculant and intermixture into sewage.Air compressor send air to air tank
4.2. Pump send flocculating suspended wastewater to the pool.
4.3. Jet flow device take air to dissolving-air tank,the air will be forced to dissolve into water under 0.35Mpa pressure and forming dissolved air water.
4.4. The dissolved air water will be sent to air flotation tank.
4.5. When the press reduce suddenly,air will dissolve out the water and form vast microbubbles,then fully contact the flocculating suspended matter and float to the surface.
4.6. Surface sludge rollers will collect the solid on the water surface.removing SS and CODcr etc.

5. Feature:
5.1 Dissolved air pump edge bibulous the edge is inspiratory, pump pressurized mix within, gas to liquid efficient dissolving, small bubbles than 30 um.
5.2 Low voltage operation, the dissolved gas efficiency is as high as 99%, release rate as high as 99%.
5.3 Tiny bubbles and suspended particles of efficient adsorption, improve the SS remove effect.
5.4 Dissolved gas water dissolving efficiency 80-100%, than traditional dissolved gas floating high efficiency three times.
5.5 Pressure-capacity curve smooth, easy to achieve automatic control, easy to operate, easy maintenance, low noise.
5.6 Large treatment capacity,high efficiency,occupies less.
5.7 Technology process and equipment sample,easy to use and maintain.
5.8 Can eliminate sludge bulking.
5.9 When working,the aerator will send air to the water,can remove the surfactant and odour effectively.At the same time,aeration can add the dissolved air quantity in the water,which will provide advantages to follow-up units.
5.10 For low temperature,low UTN,algae-containing water,air flotation technology will be the best choose.

6. Applications :
Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including:
Product recovery and reuse
Pretreatment to meet sewer discharge limits
Pretreatment to reduce loading on downstream biological treatment systems
Polishing of biological treatment effluent
Thickening of biosolids
There is a wide range of industrial and municipal applications for DAF including:
Product recovery and reuse Pretreatment to meet sewer discharge limits 
Pretreatment to reduce loading on downstream biological treatment systems Polishing of biological treatment effluent ,thickening of biosolids   
Industrial Applications
