Manganese Removal from Groundwater Role of Biological and Physico-Chemical Autocatalytic Processes

Manganese Removal from Groundwater Role of Biological and Physico-Chemical Autocatalytic Processes

In The Netherlands Belgium and other European countries manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate cost effective and sustainable because it does not make use of strong oxidants such as O3 Cl2 ClO2 and KMnO4 with the associated risk of by-product formation and over or under dosing. However application of aeration-filtration is also facing drawbacks especially the long ripening time of filter media. Due to the long ripening time water companies have to waste large volumes of treated water making this process less sustainable. Also costs associated with filter media ripening (man power electricity operational and analysis costs) are high. Therefore decreasing the filter ripening time regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal the controlling mechanisms especially of the start up face of filter media ripening are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria e. g. by limiting the back wash frequency and / or intensity. Additionally this thesis also shows that the use of freshly prepared manganese oxide containing Birnessite can completely eliminate filter media ripening time. | Manganese Removal from Groundwater Role of Biological and Physico-Chemical Autocatalytic Processes

Fluoride Removal from Groundwater by Adsorption Technology

Fluoride Removal from Groundwater by Adsorption Technology

In the Eastern corridor of Northern region of Ghana presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is however known about the factors contributing to the occurrence of high fluoride in this part of Ghana and it’s spatial distribution. Treatment of the fluoride-contaminated groundwater by adsorption is also hampered by the lack of suitable adsorbents that are locally available. Based on principal component analysis and saturation indices calculations this thesis highlights that the predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes both of which deplete Ca from the groundwater and promote the dissolution of fluorite. The mechanisms also include F-/OH- anion exchange processes as well as evapotranspiration processes which concentrate the fluoride ions hence increasing its concentration in the groundwater. Spatial mapping showed that the high fluoride groundwaters occur predominantly in the Saboba Cheriponi and Yendi districts. The thesis further highlights that modifying the surface of indigenous materials by an aluminium coating process is a very promising approach to develop a suitable fluoride adsorbent. Aluminum oxide coated media reduced fluoride in water from 5. 0 ± 0. 2 mg/L to ≤ 1. 5 mg/L (which is the WHO health based guideline for fluoride) in both batch and continuous flow column experiments in the laboratory. Kinetic and isotherm studies thermodynamic calculations as well as analytical results from Fourier Transform Infrared Spectroscopy and Raman spectroscopy suggest the mechanism of fluoride adsorption onto aluminium oxide coated media involved both physisorption and chemisorption processes. Field testing in a fluoritic community in Northern Ghana showed that the adsorbent is also capable of treating fluoride-contaminated groundwater in field conditions suggesting it is a promising defluoridation adsorbent. The adsorbent also showed good regenerability potential that would allow re-use which could make it practically and economically viable. Additional research is however required to further increase the fluoride adsorption capacity of developed adsorbent. | Fluoride Removal from Groundwater by Adsorption Technology

Autotrophic Nitrogen Removal from Low Concentrated Effluents Study of System Configurations and Operational Features for Post-treatment of A

Autotrophic Nitrogen Removal from Low Concentrated Effluents Study of System Configurations and Operational Features for Post-treatment of A

This book reports the first systematic monitoring and modelling study on water availability water quality and seawater intrusion of the Shatt al-Arab River (SAR) on the border of Iraq and Iran where causes and concentration levels of salinity have not yet been fully understood let alone addressed leading to conflicting perceptions of its origin (external or internal) the natural conditions and the practices that can explain the current critical conditions. Current scientific knowledge on the SAR salinity problem is deficient partially due to the complex and dynamic interaction between marine and terrestrial salinity sources including return flows by water users of the different water sectors in the Euphrates and Tigris rivers upstream of the SAR. The development of a new series of monitoring stations and various modelling approaches helped to better understand the interactions between these different sources. The comprehensive and detailed dataset formed the basis for a validated analytical model that can predict the extent of seawater relative to other salinity sources in an estuary and for a hydrodynamic model that can predict salinity changes. The adaptability of the models to changing conditions makes them directly applicable by water managers. The procedure can be applied to other comparable systems. | Autotrophic Nitrogen Removal from Low Concentrated Effluents Study of System Configurations and Operational Features for Post-treatment of A

Introduction to Green Chemistry

Introduction to Green Chemistry

Interest in green chemistry and clean processes has grown so much in recent years that topics such as fluorous biphasic catalysis metal organic frameworks and process intensification which were barely mentioned in the First Edition have become major areas of research. In addition government funding has ramped up the development of fuel cells and biofuels. This reflects the evolving focus from pollution remediation to pollution prevention. Copiously illustrated with more than 800 figures the Third Edition provides an update from the frontiers of the field. It features supplementary exercises at the end of each chapter relevant to the chemical examples introduced in each chapter. Particular attention is paid to a new concluding chapter on the use of green metrics as an objective tool to demonstrate proof of synthesis plan efficiency and to identify where further improvements can be made through fully worked examples relevant to the chemical industry. NEW AND EXPANDED RESEARCH TOPICS Metal-organic frameworks Metrics Solid acids for alkylation of isobutene by butanes Carbon molecular sieves Mixed micro- and mesoporous solids Organocatalysis Process intensification and gas phase enzymatic reactions Hydrogen storage for fuel cells Reactive distillation Catalysts in action on an atomic scale UPDATED AND EXPANDED CURRENT EVENTS TOPICS Industry resistance to inherently safer chemistry Nuclear power Removal of mercury from vaccines Removal of mercury and lead from primary explosives Biofuels Uses for surplus glycerol New hard materials to reduce wear Electronic waste Smart growth The book covers traditional green chemistry topics including catalysis benign solvents and alternative feedstocks. It also discusses relevant but less frequently covered topics with chapters such as Chemistry of Long Wear and Population and the Environment. This coverage highlights the importance of chemistry to everyday life and demonstrates the benefits the expanded exploitation of green chemistry can have for society. | Introduction to Green Chemistry
