摘要：

Response surface methodology using the Central Composite Rotatable Design (CCRD) model was used to optimize parameters for Acid Mine Drainage (AMD) remediation with shrimp and aquaculture farming waste (shrimp-shell and mussel byssus). The CCRD (23) consisting of three-factored factorial design with five levels was used in this study. The dependent variables were agitation, shrimp-shell and byssus content. The results were derived by computer simulation applying least squares method using STATISTICA 7 StatSoft software. Coefficient of determination and the standard errors results from the analysis of variance have shown the model to be adequate. Predicted values were found to be in good agreement with experimental values. This study has shown that the CCRD can efficiently be applied for the modeling of AMD remediation with biomaterials and it is economical way of obtaining the maximum amount of information in a short period of time, with the fewest number of experiments.
