Inclined Plate Clarifier Oil Separator Dissolved Air (DAF) for Sludge Treatment
This machine is mainly used for solid-liquid or liquid-liquid separation. Large sum of micro bubbles produced dissolving and releasing system adhere to solid or liquid particles which with the same density as wastewater to make the whole float to the surface thus achieve the goal of separation.
Working Principle
1. Add flocculant and intermixture into sewage. Air compressor
sends air to the air tank
2. Pump sends flocculating suspended wastewater to the pool.
3. Jet flow device takes 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 the air flotation tank.
5. When the press reduces 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 removing SS and CODcr etc.

Main Structure
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.
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 realized water and air fully
contact, speed up air dissolve, which is a closeness Withstand
Voltage steel tank, it is inside equipped with baffle plate,
sleeve, to speed up air and water speed, improve dissolved air
efficiency.
3) Chemical dosing system: metering pump, mixing motor, PE tank.
Equipped Equipment
1. Chemical dosing system: add PAC PAM liquid to wastewater.
2. Pipeline flocculator: Make sure PAM PAC liquid with wastewater mixed enough
