Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The water of Queshan reservoir (Jinan, China) which derived from Yellow River was treated by the technology of dual-media flofilter with GAC and sand, and the flocculation conditions, the flotation parameters and the filtration parameters were separatedly optimized. Based on the test result, PAFC was suited for Queshan reservoir water, and the optimum dosage was 2.0 mg A13+/L. HCl was added to adjust the pH of raw water, the influence of removal efficiency on turbidity was small, while the influence of removal efficiency on organic substance was comparatively large, and the influence result indicated: UV254 >; CODMn >; turbidity. The optimal value of dissolved air pressure was 0.30 MPa, and the optimal value of reflux ratio was 20% in the flotation unit. The filtration rate could not exceed 8m/h, and the filtration cycle was 3 days.
