Description
Dissolved Air Floatation is mainly for solid-liquid or
liquid-liquid separation.
Large sum of micro bubbles produced by dissolving and releasing
system adhere to solid or
liquid particles with same density as waste water to make the whole
float to the surface thus
achieve the aim of solid-liquid or liquid-liquid separation.

Advantage
1. Flow rate of one set: 1-300 m³/h.
2. Recycle flow dissolved air flotation.
3. High efficiency pressurization system providing high quantity
dissolved-air water to create
large quantities of small bubbles.
4. Custom design on different dissolved air flotation equipment and
recycle flow ratio
according to the type of wastewater and treatment requirement to achieve target
removal
effect and stability.
5. Adjustable stainless steel chain type skimmer to suit the
different quantity of sludge.
6. Integrated coagulation tank and or flocculation tank and
cleaning water tank(as optional)is
available to save the space and cost.
7. Automatic and remote controllable.
8. Material of construction: carbon steel epoxy painted, carbon
steel FRP line, stainless steel
SS304/SS316L.
