Advantages Of Central Composite Design, The star points are at some distance from the center based on the properties desired for the design and the number of factors in the design. All experiments for Fenton oxidation were designed according to RSM using central composite design CCD with the aid of design expert Version. Central composite designs are much more flexible with respect to the issue of 2 way interactions.

Types of CCD 1. Using either the Central Composite or Box Behnken design to fit a cubic model requires more experimentation so that there is at least one experiment for each term in the model. Box-Wilson Central Composite Designs CCD designs start with a factorial or fractional factorial design with center points and add star points to estimate curvature A Box-Wilson Central Composite Design commonly called a central composite design contains an imbedded factorial or fractional factorial design with center points that is augmented with a group of star points. CCC designs are the original form of the central composite design.
Central composite designs can create orthogonal blocks letting model terms and block effects be estimated independently and minimizing the variation in the regression coefficients.
The engineer creates a central composite design folio performs the experiment according to the design and then enters the response values into the folio for further analysis. A full quadratic model is fitted to the data. CCD on the other hand requires 5 different levels and 20 runs for 6 central points. They are comprised of a standard 2k factorial center points and axial points. If we had utilized a 3k design one that quickly becomes unreasonably large then we would have been able to estimate all of the higher order interactions. According to the literature review the most important parameters which affect the efficiency of Fenton process are pH initial concentrations of Dye Fe 2 and H 2 O 2 4 33 34.
