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.

Download or read book Treatment of Micropollutants in Water and Wastewater written by Jurate Virkutyte and published by IWA Publishing. This book was released on 2010-08-14 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years there has been a growing concern over the increasing concentration of micropollutants originating from a great variety of sources including pharmaceutical, chemical engineering and personal care product industries in rivers, lakes, soil and groundwater. As most of the micropollutants are polar and persistent compounds, they are only partially or not at all removed from wastewater and thus can enter the environment posing a great risk to the biota. It is hypothesized that wastewater is one of the most important point sources for micropollutants. Treatment of Micropollutants in Water and Wastewater gives a comprehensive overview of modern analytical methods and will summarize novel single and hybrid methods to remove continuously emerging contaminants - micropollutants from the aqueous phase. New trends (e.g. sensor technology, nanotechnology and hybrid treatment technologies) are described in detail. The book is very timely because the new techniques are still in the development phase and have to be realized not only in the laboratory but also on a larger scale. The content of the book is divided into chapters that present current descriptive and analytical methods that are available to detect and measure micropollutants together with detailed information on various chemical, biological and physicochemical methods that have evolved over the last few decades. Treatment of Micropollutants in Water and Wastewater will also enable readers to make well informed choices through providing an understanding of why and how micropollutants must be removed from water sources, and what are the most appropriate and available techniques for providing a cost and technologically effective and sustainable solutions for reaching the goal of micropollutant-free water and wastewater. The book will be suitable for water and wastewater professionals as well for students and researchers in civil engineering, environmental engineering and process engineering fields.

This book was released on 2019-05-21 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents recent challenges related to new forms of pollution from industries and discusses adequate state-of-the-art technologies capable to remediate such forms of pollution. Over the past few decades the boom in the industrial sector has contributed to the release in the environment of pollutants that have no regulatory status and which may have significant impact on the health of humans and animals. These pollutants also referred to as "emerging pollutants", are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. It is recurrent these days to find water treatment plants which no longer produce water that fits the purpose of domestic consumption based on newly established guidelines. This situation has prompted water authorities and researchers to develop tools for proper prediction and control of the dispersion of pollutants in the environment to ensure that appropriate measures are taken to prevent the occurrence of outbreaks due to sudden load of these pollutants in the water system. The chapters in this book cover a wide range of nano and bio-based techniques that have been designed for the real time detection of emerging contaminants in environmental water sources, geochemical models that are continuously improved for the prediction of inorganic contaminants migration from the mine solid wastes into ground and surface waters. Remediation strategies are also discussed and include effective techniques based on nanotechnology, advanced membrane filtration, oxidative and bio-degradation processes using various types of nanocatalysts, biocatalysts or supporting polymer matrices which are under advanced investigations for their implementation at large scale for the removal of recalcitrant pollutants from polluted water. Nano and Bio-Based Technologies for Wastewater Treatment: Prediction and Control Tools for the Dispersion of Pollutants in the Environment is divided is two sections. The first section covers the occurrence of emerging pollutants in environmental water while the second section covers state-of-the-art research on the removal of emerging pollutants from water using sustainable technologies. A total of 13 chapters addressing various topics related to the two sections are essentially based on recent developments in the respective field which could have a significant impact on the enhancement of the performance of wastewater treatment plants around the world, and especially in developing countries where access to clean and safe water remains a daily challenge.
