【 摘 要 】

In order to investigate the action of the flocculating agents Panfloc and Panclar a full factorial design 23 and a Central Composite design 22 were carried out. The control variables were the flocculant concentration, pH and temperature. The response variables were phenolic compounds reduction and spectral area reduction. The best conditions of treatment was hydrolyzate at pH 9 for both coagulants, but the use of Panfloc was more effective in the phenolic compounds reduction (73.9%) and spectral area reduction (65.8%).
