 Dissolved Air Flotation Separator for Landscape Wastewater Treatment       Product Description   Principle of SDAF   The SDAF Separator provides effective separation of suspended solids, fats, oils and greases from liquids by dissolved air flotation. Flotation of the solids is accomplished by the introduction of tinny air bubbles into the process water. As the bubbles rise, they attach themselves to the particales in suspension and carry them to the surface for removed.   Application Corresponding  water quality : high SS, and the specific gravity of suspended solids or contaminants is generally slight greater than water, settle effectively and have a pretty clear tendency to precipitate, like:     Oil and Fats, Food Industry effluents with high solids concentration,
    Sludge Thickening,
    Galvanizing Electroplanting,
    Pharmaceutical Industry,
    Leather Industry,etc.   Features of SDAF3-150   1. Design treatment capacity: 120m3/h   2. High-rate clarifier for high SS water (light particles, oil and colloid)
  3. Fully(100%) manufactured in the factory, and no need secondory 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 & continious operation.
  6. Design life: Carbon steel material: >10years;
                      Stainless steel material: >20years.     Advantages of SDAF3-150   1. Extremely high srcaping speed (2-3 times faster than conventional design) and safty operation because of using fully reverse and closed scraper (Patent No:ZL 2011 2 0092349 . 4).
  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 V-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.   Specifications of SDAF3-150
