The study of the Blue Cibacron (BC) treatment process through an experiment factorial design allows us to determine a function ƒ such that (Y= ƒ(X1, X2, …, Xn)) existing between magnitude Y which is the decrease of coloration (called response), and variables Xi , which are biomass (m), pH and Temperature (called factors). A complete factorial design (23) was made in order to determine the factors and their interactions which have a statistically significant influence on the studied response. Temperature has a significant effect on the reduction of coloration; by contrast, pH and biomass (m) does not have a significant effect. On the other hand, the interactions between the three factors have significant effects on the decrease of coloration.
