1. Description
Dissolved air flotation machine is mainly for solid-liquid and liquid-liquid separation.
2. Working theory
YW series Dissolved Air Floatation Machine is mainly used for solid-liquid separation. Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or liquid particles which with the same density as waste water to make the whole float to the surface thus achieve the goal of separation.
3. Application
1) Separating small particles and algae in groundwater.
2) Recovering valuable matters in industrial sewage such as paper pulp.
3) Acting as secondary sedimentation tank to separate and concentrate suspended particles and sludge.
4.Features of DAF
1).Design treatment capacity:5-300 m3/h.
2).High-rate clarifier for high SS water (light particles, oil and colloid).
3).Fully(100%) manufactured in the factory, and no need secondary welding. It costs 3h for 2 manpower to assemble.
4).Indoor or outdoor layout (environmental temperature should be over 0°C).
5).Apply to automatic & continuous operation.
6).Design life: Carbon steel material:>10years;
            304 Stainless steel material:>20years.
            316 Stainless steel material:>25 years.
5.Advantages of DAF
1).Extremely high scraping speed (2-3 times faster than conventional design) and safety operation because of using fully reverse and closed scraper.
2).High hydraulic load and low footprint because of horizontal plates in the separation zone, more effective separation and optimization hydraulic flow in the separation area.
3).Better outlet water quality because of W-shape sludge sedimentation hopper.
4).Effectively minimize chemical consumption because of re-flocculation performance of reverse scraping design.
5).No blind angle in scum collection chamber.
