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

Activated Carbon Adsorption

Activated Carbon Adsorption

High surface area a microporous structure and a high degree of surface reactivity make activated carbons versatile adsorbents particularly effective in the adsorption of organic and inorganic pollutants from aqueous solutions. Activated Carbon Adsorption introduces the parameters and mechanisms involved in the activated carbon adsorption of organic and inorganic compounds. This text brings together the most significant research on surface structure and processes adsorption theories and isotherm equations and applications from the latest literature on carbon adsorption. The book clearly explains the surface-related interactions of activated carbons their energetics and the applicability of adsorption isotherm equations and their deviation from adsorption data. It then explores numerous applications in a wide range of areas such as nuclear technology vacuum technology food technology pharmaceuticals and medicine gas storage oil refining and environmental remediation. Topics include: oils and fats molecular sieves refining of liquid fuels pesticides dyes drugs and toxins. Three chapters are dedicated to environmental applications including the adsorption of halogenated organic compounds and the removal of hazardous gases and vapors organo-sulphur compounds and other inorganic compounds from wastewater and groundwater. Activated Carbon Adsorption presents a complete survey of the growing number of state-of-the-art applications supported by a compilation of the latest perspectives in research concerning carbon surfaces and their adsorption processes from aqueous solutions. Its unified approach promotes further research towards improving and developing newer activated carbon adsorbents and processes for the efficient removal of pollutants from drinking water and industrial effluents.

Biological and Biotechnological Control of Insect Pests

Biological and Biotechnological Control of Insect Pests

Pest and disease management continues to challenge the agricultural community. The rise in new pest and crop problems juxtaposed with public concern over pesticide use and more stringent environmental regulations creates the need for today's agricultural producers to stay current with new technologies for producing quality crops profitably. Biological and Biotechnological Control of Insect Pests presents an overview of alternative measures to traditional pest management practices utilizing biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals caused by concerns over environmental health and public safety has resulted in the development of alternative reduced risk crop protection products. These products less toxic to the environment and easily integrated into biological control systems target specific life stages or pest species. Predation - recognized as a suitable long term strategy - effectively suppresses pests in biotechnological control systems. Biological and Biotechnological Control of Insect Pests covers these topics and more. It explores the current approaches in alternative solutions such as: biological control agents parasites and predators pathogenic microorganisms pheromones botanical insecticides genetic control genetic engineering of plants and biocontrol agents and government regulations for biocontrol agents and recombinant DNA technology. This book will be a useful resource to entomologists agronomists horticulturists and environmental scientists.

Novel Bioremediation Processes for Treatment of Seleniferous Soils and Sediment

Novel Bioremediation Processes for Treatment of Seleniferous Soils and Sediment

The aim of this Ph. D. was to develop a technology for the remediation of seleniferous soils/sediments and to explore microbial reduction of selenium oxyanions under different respiration conditions and bioreactor configurations. Seleniferous soil collected from the wheat-grown agricultural land in Punjab (India) was characterized and its soil washing was optimized by varying parameters where addition of oxidizing agents showed a maximum selenium removal efficiency. Aquatic plants Lemna minor and Egeria densa were used to study phytoremediation of the selenium-rich soil leachate containing oxidizing agents. Additionally migration of the soluble selenium fraction from the upper to the lower layers and its subsequent reduction and accumulation in the lower layers of the soil column was observed during soil flushing. Furthermore the soil leachate containing selenium oxyanions obtained from soil washing was treated in a UASB reactor by varying the organic feed. Ex situ bioremediation of selenium oxyanions was studied under variable conditions. An aerobic bacterium (Delftia lacustris) capable of transforming selenate and selenite to elemental selenium was isolated and characterized. Anaerobic bioreduction of selenate coupled to methane oxidation was investigated in serum bottles and a biotrickling filter using marine sediment as inoculum. Finally the effect of contamination of other chalcogen oxyanions (tellurium) on selenium bioreduction was studied in a continuous system (UASB reactor). | Novel Bioremediation Processes for Treatment of Seleniferous Soils and Sediment
