DAF Dissolved air flotation units for slaughter wastewater treatment machine
1. Add flocculant and intermixture into sewage.Air compressor send air to air tank 2. Pump send flocculating suspended wastewater to the pool. 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. The dissolved air water will be sent to air flotation tank. 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. 6. Surface sludge rollers will collect the solid on the water surface.
Advantages of the DAF plant
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.
Slagging remove system
Slagging remove system is consist of Scraper plate, motor, reducer,chain,gear etc. 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.
Because different country use different national standard of pipes, so this diameter of this pipes maybe defferent.
Our company provide supporting flange, client only need to weld the pipes with this flanges is ok, very easy and convenient.
Funnel shaped sewage outlet .
Usually the sludge at bottom of dissolved air flotation is sucked out by sludge pump or flow out by gravity. Use pump to suck out would add running cost, and flow out by gravity will very flow,this will effect machine running.
So, our company developed funnel shaped sewage outlet, so sludge can flow out by gravity easily and not use pump.
The pipeline flocculator have 9 model,here are the list:
1 - 1
2 - 5
Make sure PAM PAC liquid with wastewater mixed enoughly
