Dissolved air flotation: Is it really a suitable solution for industrial purification processes?

There is no doubt that one of the most important problems we face today is water scarcity as a result of increasing urbanization and climate changes. This situation necessitates sustainable water management. Although many methods have been implemented to control water pollution from past to present, the interest to usage of flotation (dissolved air flotation) as physical treatment method, has been gradually increasing its application areas in recent years. In this review, the recent developments in the application of dissolved air flotation in waste/recirculating water treatment processes was examined to provide a comprehensive understanding of the current status.
