Combination of ozone, H₂O₂, and adsorption using granular activated carbon for shampoo synthetic wastewater treatment

Shampoo is one of the pollutants found in domestic liquid waste which is usually disposed of directly into the environment without first processing so it is harmful to the environment. This research uses the principle of Advanced Oxidation Process (AOPs). The combination of advanced oxidation method with ozone, H₂O₂ and activated carbon adsorption is known to be able to degrade the content of harmful organic and inorganic compounds. This study compared four methods, namely ozonation, H₂O₂, activated carbon adsorption and a combination of the three. To determine the optimal conditions for processing liquid shampoo, variations were made on ozone doses of 1.2, 3, and 5 g / hour and the amount of activated carbon used was 50, 100, and 150 grams. This study aims to evaluate the effect of ozone concentration, H₂O₂ and activated carbon absorbent on the performance of shampoo wastewater oxidation process and evaluate the degradation in optimum conditions. Based on the research and analysis carried out, the best results obtained was the combination of advanced oxidation method with ozone, H₂O₂ and activated carbon adsorption using ozonator 3 gr/hr, 1,5 mL H₂O₂ with 4 times injections and 150 gram GAC, which decreased the COD value by 51.43%, TOC by 39, 31%, Surfactant by 32.2%, and pH by 7.68%, but it is not effective in reducing the value of TDS in shampoo wastewater.
