DAF System Air Flotation Machine Applied To Leather Wastewater
Treatment
Features
(1) Large capacity, high efficiency and small occupying space.
(2) Compact structure, easy operation and maintenance.
(3) Silt expansion elimination.
(5) Aerate to the water while air floating, it has an obvious
effect to the elimination of active
agent and foul smell in water. Meanwhile, the increased dissolved
oxygen provides a
favorable condition to the follow-up process.
(6) It can achieve the best effect in adopting this method when
disposing the water with lower
temperature, lower turbidity and more algae.
Suitable area:
slaughtering, starch, pharmaceuticals, papermaking, printing and
dyeing,
leather and tannery, petrochemical industry, domestic wastewater,
etc.
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.
Application
(1) Remove oil and TSS.
(2) Separate small particles and algae in groundwater.
(3) Recover valuable products in industrial sewage such as paper
pulp.
(4) Act as secondary sedimentation tank to separate and concentrate
suspended particles
and sludge.
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.
