Wastewater treatment using DAF for process water

Dissolved air flotation (DAF) is a separation process based on the generation of microbubbles (Santana et al., 2012) and can be used as an alternative for the wastewater treatment for water reuse in apatite flotation. DAF is based on the variation of the air solubility in water

Application of dissolved air flotation on separation of

2012-7-1  Highlights The dissolved-air flotation is applied on separation of waste plastics. The depressing ability of TA on waste plastics is higher than that of LS. Increasing conditioning time benefits the adsorption of wetting agent. W-ABS and w-PS could be separated by dissolved-air flotation using 25 mg L −1 TA. A hydrogen bonding adsorption model with hydration shell as a mesophase is proposed.
