Comparison of Physicochemical Concentration on Temperature Effect of Crude Oil Contaminated Water Environment

Abstract

The bio-adsorbents used are plantain stem fiber, banana stem fiber and palm fruit fiber and the investigation was aimed to examiner  the effect of temperature on the performance of the bio-adsorbents in a packed bed unit for the mitigation (reduction or removal) of total petroleum hydrocarbon (TPH) from the fresh water medium using agro based fibre, which was prepared by subjecting the agro materials into sun and room dried before grounding into powder form of particle size of 50   and  and the mass of the used adsorbent is 1500g with particle size ratio of 1:1:1 in terms of , , and , was placed in the packed bed unit connected in series. The investigation was performed at packed bed unit adsorption of  of flow rate, constant packed bed unit height of 27cm. The effect of temperature was monitored with respect to change in physiochemical properties microbial count, total petroleum hydrocarbon (TPH) mitigation, resident time and rate of TPH remediation.The comparison of the microbial count concentration of the HUB isolated and identified in each biounits with the effect of temperature reveals the degree of microbial in this order of PSRTR1 > PFFRTR1 > BSRTR1 > PSRTR1 > PFFSDR1 > BSSDR1, PSRTR2 > PFFRTR2 > PSSDR2 > BSRTR2 > PFFSDR2 >BSSDR2 and PSRTR3 > PFFRTR3 > PSSDR3 > BSRTR3 > PFFSDR3 > BSSDR3. In this case, the plantain fibre of room dried performance was high compared to others in the packed bed units R1, R2 and R3. The effect of temperature on bio-adsorbent performance in terms of the penetration and diffusion of the fluid from inlet to outlet {residence time) is dependent of temperature and this is a major contributing factors in bio-adsorption. The research work predicted that the best operating temperature for contaminants removal using bio-adsorbent of the ratio of particle size of 1:1:1 mixture of 50µm, 150µm and 200µm was achieve at temperature of 45^oC. Indeed, this thesis has revealed the significance of temperature effect on bio-adsorbent performance in bioremediation treatment of contaminants in packed bed unitss, especially the effectiveness of plantain fiber.
