High fluoride concentration in groundwater has made many drilled boreholes unusable for drinking in parts of Northern region of Ghana. Treatment of the groundwater by adsorption is also hampered by the lack of suitable locally available adsorbents. This thesis highlights through principal component analysis and saturation indices calculations that predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes, which deplete Ca from the groundwater, and promote the dissolution of fluorite. Additionally, aluminium oxide coated media…mehr

Produktbeschreibung
High fluoride concentration in groundwater has made many drilled boreholes unusable for drinking in parts of Northern region of Ghana. Treatment of the groundwater by adsorption is also hampered by the lack of suitable locally available adsorbents. This thesis highlights through principal component analysis and saturation indices calculations that predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes, which deplete Ca from the groundwater, and promote the dissolution of fluorite. Additionally, aluminium oxide coated media is capable of reducing fluoride in water, suggesting it is a promising defluoridation adsorbent.

Autorenporträt
Abdulai Salifu is a Civil and Environmental Engineer, and obtained his BSc. degree (Civil Engineering) from the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. He obtained his Post-Graduate diploma degree (passed with distinction) in Community Water Supply and Sanitation, from Loughborough University of Technology (LUT), England (U.K) and his MSc. degree in Environmental Engineering from the University of Newcastle upon Tyne, England (U.K). He worked for several years in the water sector in Ghana as a Water and Sanitation Engineer, where he worked in multi-disciplinary team professionals comprising of; Hydrogeologist, Sociologists, Health and Hygiene Education Specialist, IT Specialist and Planners, involved mostly in the provision of water supply and sanitation facilities as well as health/hygiene education to rural communities and small urban towns. He was involved in the planning and implementation of several water and sanitation projects in the Northern region of Ghana, financed by several External Support Agencies (ESAs), including the World Bank, European Union (EU), Agence Francais de Developpment (AFD), UNICEF, Japanese International Corporation Agency (JICA) and the Canadian Development Agency (CIDA).
