Influences of NOM and Turbidity on PAC Adsorption/DAF Hybrid Process for the Simultaneous Removal of Trihalomethanes and Suspended Solids |
| 초록 |
The influences of NOM and turbidity on the hybrid process consisting of PAC adsorption and dissolved air flotation were systematically investigated for the simultaneous removal of trihalomethanes (CHCl3, CHBrCl2, CHBr2Cl and CHBr3) and suspended solids. Before studying the hybrid system, adsorption equilibrium and kinetics of trihalomethanes were examined using powdered activated carbons (PAC). Three types of powdered activated carbons (wood-based, coal-based, coconut-based) were used. On the other hand, the removal efficiency of suspended solids was evaluated from the results of conventional gravity sedimentation and DAF. A kinetic model for DAF process was employed to describe the bubble-floc collision and agglomeration, as well as the rising velocity of bubble-floc agglomerate. It was found from our study that the hybrid process consisting of PAC adsorption and DAF can be widely applied for the water and wastewater treatments. |
