The transmembrane pressures applied were 1.0, 2.0 and 3.0 bar, and temperature was kept constant at 20ºC.

The clarification process with membranes achieved a reduction of turbidity and color superior to 92 and 16%, respectively. In the clarification by adding coagulating agents we verified a reduction superior to 78 and 46% to turbidity and color, respectively. </span></span></span></p><p><span style="font-family: Times New Roman; font-size: small;"> </span><span style="font-size: x-small;"><span style="font-family: Aldine401 BT;"><span style="mso-ansi-language: EN-US;" lang="EN-US"> </span></span></span></p><p><span style="font-family: Times New Roman; font-size: small;"> </span></p> |
