Book excerpt: Selected Proceedings of the IWA International Conference, held in Kuala Lumpur, Malaysia, 29-31 October 2001. The IWA Conference on Water and Wastewater Management for Developing Countries was the first conference specially organized for developing countries after the merger between the International Association on Water Quality (IAWQ) and the International Water Services Association (IWSA). Its aim was to promote the concept of appropriate technologies for water and wastewater management, and to enhance linkages between institutions, practitioners and research groups working on low-cost treatment and waste recycling systems, and promote collaborative R&D. The outcome was a highly successful and well attended conference, with more than 300 participants from 21 countries. From this large and high quality programme (there were over 130 oral presentations), 42 articles have been selected after peer review. They cover the three major subject areas of the conference: operation and management; water supply and treatment; and wastewater technology. These proceedings thus contain not only the important details on the outcomes of the conference, but also demonstrate the significant advances being made in research and development on water and wastewater management in developing countries by researchers and practitioners, from developing and developed countries alike.

Book Effects on Surface Area Intake Capacity and Regeneration of Monoethanolamine

Download or read book Effects on Surface Area Intake Capacity and Regeneration of Monoethanolamine written by Saad Khalil and published by . This book was released on 2018-10-09 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2018 in the subject Engineering - Chemical Engineering, The University of Malaya, language: English, abstract: Granular palm shell activated carbon (AC) was impregnated separately with monoethanolamine (MEA) and 2-amino-2-methyl-1-propanol (AMP) to improve its natural capacity and selectivity for carbon dioxide (CO2) adsorption. The total surface area, micropore volume, as well as the heterogeneity of the impregnated AC particles was considerably reduced due to impregnation. CO2 intake of impregnated 500 μm AC particles improved significantly and adsorptive capacity of 500 μm MEA-impregnated AC particles improved by 172 % and 44 % comparing to non-impregnated and AMP-impregnated AC particles respectively. Solid state amine stoichiometric results indicated that adsorption capacity of unhindered amine (MEA) is higher than that of hindered amine (AMP) by 50 % contrary to liquid amines standard stoichiometry. Exhausted AMPimpregnated beds were regenerated by sweeping at room temperature with stream of pure nitrogen (N2) flowing at 60 ml/min for 4 hours. Heating up to 75 °C was required to regenerate exhausted MEA-impregnated beds. Increasing feed gas flow rate has adverse effect on breakthrough time more than increasing bed operating temperature. Breakthrough time was utilized to evaluate the performance of the different adsorption beds.

Book Kinetic Study of Activated Carbon from Palm Kernel Shell for Copper Removal

Download or read book Kinetic Study of Activated Carbon from Palm Kernel Shell for Copper Removal written by Nur Hidayu Binti Misran and published by . This book was released on 2016 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of alternative activated carbon has been resolved to replace the costly activated carbon to remove unwanted heavy metals from contaminated water at low cost. Heavy metals are very toxicity and can harm human body. The environmental pollution became increase due to the discharge of wastewater including heavy metals and toxic nature of copper affects water resources. In this study, activated carbon produced locally from palm kernel shell was examined for the copper removal from aqueous solution by using adsorption process. Palm kernel shell not just available to get but inexpensive material that have ash content, fixed carbon, high carbon and low inorganic content. Adsorption studies conducted in completely to shown the ability of the produced activated carbon to remove copper from aqueous solutions in certain range of pH. The investigation was carried out by studying the influence of pH (1-5), adsorbent dosage (0.3-1.5 g) and initial concentration (150-350 mg/L). The result of the study shown that activated carbon from palm kernel shell with large surface area has high percentage capacity of copper removal compared to small surface area. From the result showed that the optimum parameters for maximum removal efficiency were follows as adsorbent dose (1.5 g), pH (5) and initial concentration (150 mg/L). Based on the batch adsorption experiment, the adsorption isotherm studies indicated that Langmuir model fits better for the present case. While adsorption kinetic indicated that pseudo second order model is the best for the present case.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of batch laboratory studies were conducted in order to investigate the practicability of palm kernel shell (PKS)-based activated carbon for removal of basic dye, Basic Blue 9 (BB 9) and acid dye, Acid Orange 52 (AO 52) from their aqueous solutions. Three different particle sizes of PKS were used and categorized as PKS - S, PKS - M and PKS - L. The adsorption capacities of the PKS-based activated carbons were compared with those of commercial grade coal-based activated carbons at the same conditions. All batch experiments were carried out at a constant temperature of 28oC (±2oC) using incubator shaker that operated at 150 rpm. Batch equilibrium study shows that Adsorption of BB 9 and AO 52 were highly pH dependent. Removal of BB 9 increased with pH with maximum removal observed at pH 7.0, and decreased thereafter with further increase in the initial pH. However, pH effect on AO 52 removal shows that AO 52 removal decreased with an increase in initial pH with the optimum initial was observed at 3.5. batch equilibrium data also a had good agreement with the Langmuir, Freundlich and Redlich-Peterson isotherm models with correlation coefficients > 0.9. Overall, the Redlich-Peterson isotherm showed the best fit for all adsorbents under investigation in terms of correlation coefficient as well as error analysis of the results. For all the systems in this study, the analysis of isotherm shape factor showed that adsorption was favorable. For the adsorbents under investigation, PKS-S has the highest adsorption capacity followed by PKS-M. PKS-L and commercial coal based pellet form have almost equally-balanced adsorption capacity. Of all the adsorbents, commercial coal-based in powder form exhibits the lowest adsorption capacity. Obtained results revealed that PKS based activated carbon is a highly potential alternative adsorbent for treatment of dye-containing wastewater. The maximum capacity of the adsorbents for BB 9 were 333.33 mg/g, 322.58 mg/g and 212.77 mg/g for PKS - S, PKS - M and PKS - L, respectively, while for powder and pellet commercial grade coal based, the capacities were 204.08 mg/g and 217.39 mg/g, respectively. On the other hand, the maximum capacities of the same adsorbents for AO 52 were 344.83 mg/g, 333.33 mg/g, 263.16 mg/g, 238.09 mg/g and 322.58 mg/g, respectively. Adsorption capacities of the same adsorbents were found to be higher for adsorption of AO 52 compared to those of BB 9 due to the smaller molecular size of the former. Batch kinetic studies were also performed to investigate the rate limiting of the adsorption process. Results obtained revealed that the adsorption of both BB 9 and AO 52 was rapid at the beginning, but approached equilibrium slowly. Experimental data can be modeled using pseudo-second-order kinetic model as first order kinetic model does not represent the whole range of adsorption process. Other than that, intraparticle diffusion was found to be prominent at a certain stage of adsorption but it would not be the only limiting step that controlled the adsorption dynamic. Kinetic data also showed that the adsorption rates were a function of initial adsorbate concentration, adsorbent particle size and adsorbent mass. For all systems under consideration, the values of k2 increased significantly as adsorbent dose increases. Nevertheless, the values of k2 were inversely proportional to the initial adsorbate concentration and adsorbent particle size. On the other hand, values of kp were found to be directly proportional to the initial adsorbate concentration but decreased gradually as adsorbent particle size and adsorbent dose increases.
