In this chapter, samples taken from the wastewater treatment plant inlet were mixed with 5 different activated carbons produced by chemical activation for 2 minutes at 150 rpm and 20 minutes at 40 rpm, and then left to stand for 60 minutes. Experiments were conducted on these prepared samples to determine Chemical Oxygen Demand (COD), pH, electrical conductivity, turbidity, and color values. Additionally, Surface Analysis and Porosity (BET), density, Fourier Transform Infrared Spectroscopy (FT-IR) analysis, and Field Emission Scanning Electron Microscopy (FE-SEM) images were interpreted. The results of this study also revealed that activation with zinc chloride is a more effective method than phosphoric acid in improving micro- and mesopore structure. These f indings once again demonstrate the critical impact of activation agents and process parameters used in activated carbon production on material properties. Furthermore, this study resulted in the conversion of waste products into more economical products, and showed that the produced activated carbons are more usable compared to commercial activated carbons.
