ABSTRACT

The study examined the impact of temperature on the performance of the bioadsorbents in a packed bed unit for the mitigation (reduction or removal) of total petroleum hydrocarbon (TPH) from the fresh water medium using agro-based fiber, which was prepared by subjecting the agro materials to sun and room drying before grinding into powder form of different particles. The bioadsorbents used are plantain stem fiber, banana stem fiber, and palm fruit fiber. The investigation was performed at packed bed unit adsorption of o.2m3/sec of flow rate, constant packed bed unit height of 27cm. The impact of temperature on changes in physiochemical characteristics, microbial count, mitigation of total petroleum hydrocarbons (TPH), resident time, and pace of TPH remediation was observed. However, the equilibrium uptake and rate constants of Yoon-Nelson (KYN), Thomas (KTh), and Bohart-Adams (KAB) were determined using the adsorption parameters of the Yoon-Nelson, Adams-Bohart, and Thomas models. In fact, changes in KYN, KTh, KAB, and q0 were discovered, and correlation coefficients between these variables were found to be between 0.9165 and 0.9999. Performance efficiencies of up to 99.99% were displayed in operating temperature breakthrough plots, which illustrate how temperature influences adsorbent performance. Each packed bed unit's fluctuation in Total Petroleum Hydrocarbon (TPH) concentration as well as the physicochemical characteristics of the pollutants were observed before and after treatment. As polluted water medium travels through each of the packed bed units, the TPH concentration decreases, and this decline is regulated by temperature fluctuation.
