The Use of Factorial Design for Analysis of Mercury Removal Efficiency Using Palm Oil Fuel Ash

A two-level half fractional factorial design was employed to evaluate the factors that have the greatest effect on the mercury removal efficiency. Several factors can influence the mercury removal using palm oil fuel ash (POFA). The aim of this study was to examine the main and interaction effects o...
