Abstract

Dissolved air flotation (DAF) is an efficient means of separating solids from liquids by extracting suspended solids to the surface for removal. A patented air-dissolving system has been developed for use in laboratory bench-study and field pilot-scale studies. This system evaluates the removal efficiency when remediating the groundwater of a RCRA (Resources Conservation and Recovery Act) site (SITE) for solids and metals. The DAF effluent has been found to yield a turbidity as low as 4 NTU compared to 7∼10 NTU obtained from the current sedimentation process.
