Removal of color and turbidity and comparison of means (Fisher’s LSD test) for the color parameter.

Treatment (coagulant concentration, mg·L^−1)	Removal of color (%)	Removal of turbidity (%)
100	66.92^c	82.23
110	80.27^b	86.50
120	80.27^b	85.83
130	83.76^a	89.76

Same letters indicate the same means for the removal of color among the treatments ( value > 0.05).
