  • Can dissolved air flotation be used in industrial wastewater treatment?
  • Applications in industrial wastewater treatment Dissolved air flotation (DAF) has been successful in treating industrial wastewaters. In many cases, such as in poultry effluent treatment, DAF proves to be an effective pre-treatment technology by reducing the organic load of the wastewater.
  • 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 are the applications of dissolved air flotation?
  • The applications for dissolved air flotation are expanding into more areas of industrial pretreatment, resource recovery and water treatment. Improvements in DAF design, including shape and whitewater systems, have improved process performance and reduced the size and cost of DAF systems.
  • What is dissolved air flotation (DAF) technology?
  • Dissolved air flotation (DAF) technology is one of the efficient techniques for purification of many types of wastewaters which contain pollutants less dense than water. Nowadays, due to high quality standards, wastewaters should be treated with high quality wastewater treatment techniques which meet the appropriate standards.
