This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated carbon is a widely used functional material. One of the most significant and resource demanding areas of activated carbon application is wastewater treatment in industry scale. The largest challenge, manufacturers face nowadays is the cost of commercially produced activated carbon. Moreover, the process of activated carbon regeneration is often complicated and cost demanding. The aim of this study is to investigate suitable conditions for production of activated carbon from raw materials, namely - from olive pits. This would provide a profitable methodology of production of activated carbon from the cheap and renewable material. Four factors, known to affect the process of carbon activation were investigated in this study: nitrogen gas flow rate (200 - 400 mL/min), concentration of zinc chloride, as a chemical activator (25 -- 50 %), temperature of activation (600 - 800 °C) and activation time (1.5 - 3 hours). The quality of activation was refereed by comparing specific surface area for each of the factor combinations --

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was designed to investigate optimal conditions of the activated carbon preparation from date pits using zinc chloride solution as a chemical activator. Activation conditions varied were inert (N2) gas flow rate, impregnation ratio, activation temperature and time. Factorial analysis and analysis of variance were implemented to study the mutual influence of these conditions on the surface properties of the activated carbon samples prepared. It was found that the iodine number and the surface area are influenced by all four activation parameters. In the same time, the methylene blue number is only influenced by the activation temperature and time. The optimal conditions for the preparation of the activated carbon from date pits were found to be 200 mL min−1 of nitrogen gas flow rate, 25% zinc chloride solution concentration, 800 °C activation temperature and 3.0 hours of activation time. These activation conditions allowed to achieve 407.150 mg g−1 of iodine number, 25.38 mg g−1 of methylene blue number and 390.50 m2 g−1 of the surface area --

This book was released on 2018 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated carbon is and has been one of the most efficient agents applied in water and wastewater treatment. However, commercially produced activated carbon can be expensive and is normally produced from non-renewable sources. In this study the aim is to generate activated carbon from a renewable and low-cost materials that occur naturally and are generally discarded. Factors studied influencing the efficiency of the activation process included activation temperature (600 °C, and 800 °C), carbonization time (1 hr, and 3 hr), and nitrogen flow rate (200 mL/min, 400 mL/min), impregnation ratio (25% ZnCl2, and 50% ZnCl2) and activation by ZnCl2 as chemical agent. Impregnation ratio refers to the concentration of chemical agent that was used to activate the carbon. The maximum surface area of activated carbon is 557.2 m2/g at 200 mL/min of flow rate, 50% of ZnCl2, 800 °C, and 3 hr of activation time --

Book Synopsis Adsorption Technology in Water Treatment by : Eckhard Worch
Download or read book Adsorption Technology in Water Treatment written by Eckhard Worch and published by Walter de Gruyter. This book was released on 2012-08-31 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption processes have played a central role in water treatment for many years but their importance is on the rise with the continuous discoveries of new micropollutants in the water cycle (pharmaceuticals for example). In addition to the classical application in drinking water treatment, other application fields are attracting increasing interest, such as wastewater treatment, groundwater remediation, treatment of landfill leachate, and so on. Based on the author's long-term experience in adsorption research, the scientific monograph treats the theoretical fundamentals of adsorption technology for water treatment from a practical perspective. It presents all the basics needed for experimental adsorption studies as well as for process modelling and adsorber design. Topics discussed in the monograph include: introduction into basic concepts and practical applications of adsorption processes; adsorbents and their characterisation, single and multi-solute adsorption equilibria, adsorption kinetics, adsorption dynamics in fixed-bed adsorbers and fixed-bed adsorber design, regeneration and reactivation of adsorbents, introduction into geosorption processes in bank filtration and groundwater recharge. According to the increasing importance of micropollutants in the water cycle, particular attention is paid to their competitive adsorption in presence of background organic matter. Clear illustrations, extensive literature references and a useful index make this work indispensible for both scientists and technicians involved in water treatment.

Book Synopsis Biochar for Environmental Management by : Dr. Johannes Lehmann
Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.
