  • What is dissolved air flotation (DAF)?
  • Dissolved air flotation (often abbreviated DAF) is water treatment process in which suspended solids, metals, and also particulate matter are removed to clarify the wastewater. The clarified water, resulting from the DAF treatment, can be reused or discharged to the sewer depending on the type of wastewater treatment.
  • What are the different types of flotation processes for wastewater treatment?
  • There are two types flotation processes for wastewater treatment: (a) dissolved air flotation and (b) dispersed air flotation or induced air flotation or IAF. The expression “flotation” or DAF is used for dissolved air flotation in this chapter.
  • What is a DAF treatment?
  • DAF treatment clarifies wastewater and although it uses more energy than for the sedimentation process because energy is needed to compress the air and design implementation is required for wastewater treatment on a large scale, a DAF treatment assists in meeting water regulatory standards.
  • Can DAF be used to treat petroleum refining wastewater?
  • The feasibility of using DAF for treating the petroleum refining wastewater has been demonstrated by professional engineers many times worldwide. LIWT and KEC together have designed and installed too many DAF (Supracell) and DAFF (Sandfloat) units for major petroleum refineries around the world.
