Wastewater from various industries contains a high concentration of dyes. Dyeing wastewater discharged into natural receiving waters without treatment; they are dangerous for both of the environment and human health.Therefore, it is necessary to remove the dyes before it is discharged to the receiving environment. In this study, full factorial modeling of methyl red removal was studied by using adsorption method which is widely used in dye removal with natural and modified prina adsorbent. 23 factorial design is used in the modeling method. In there 3 factors; adsorbent content (0.03g/30mL - 0.3g/30mL), initial dye concentration (30mg/L - 300mg/L) and adsorbent type (natural and biochar pomace) were selected. These factors were studied in two low (-1) and high (+1) levels. Effects of selected factors on adsorption efficiency; adsorbent type > initial concentration> adsorbent dosage. In addition, removal efficiencies up to 88% were obtained with biochar prina and it was found that prina is a good alternative adsorbent for methyl red removal.
