【 摘 要 】

In this work, theefficiency of clarification treatment (coagulation, flocculation and sedimentation)with polyaluminum chloride (PAC) and aluminum sulfate (SA) as coagulants wasevaluated in the removal of 7 microcontaminants (diclofenac - DCF, sulfamethoxazole- SMX, ethinylestradiol - EE2, bisphenol-A - BPA, estradiol - E2, estrone -E1 and estriol - E3) in water of low and high turbidity. The clarification treatmentled to poor removal rates (40% at most) for all microcontaminants except SMXwhich exhibited intermediate removal efficiency (67 to 70%). Overall, PAC applicationyielded better performance compared to SA.
