Description

Sorption technique was employed to remove heavy metals from gold mining effluent using natural and plant materials for sustainability. An assessment of the effluent quality of a gold mining company in Ghana indicated that arsenic, copper and cyanide were the major pollutants in the process effluent. Arsenic and copper were successfully removed from the effluent by the studied materials. The research showed that the down-flow fixed-bed treatment configuration is an ideal system for the simultaneous removal of copper and arsenic from low concentration gold mining effluent, in addition to other heavy metals present in very low concentrations.

Reviews

"The authors of this book set out to achieve the goal of presenting electromagnetics for electrical machines in a simple and systematic manner. I think they achieve that goal. They reduce Maxwell’s equations to Laplace’s equation, Poisson’s equation, wave equation, and eddy current equation and apply them to electrical machines."

—Matthew Sadiku, Prairie View A&M University

"I particularly value the approach taken of developing accurate theoretical electromagnetic models for several electrical machine structures. Traditional approaches of using lumped element models for machine parts, and then trying to modify the resulting equivalent network by taking into account the effect of these elements having non-zero physical size in a piece-meal fashion do not develop the user’s basic comprehensive insight into all aspects of the electromagnetic fields which can have some effect on machine behavior."

—Philip H. Alexander, Electrical and Computer Engineering, University of Windsor

About the Series

IHE Delft PhD Thesis Series

IHE Delft PhD programme leads to a deepening of a field of specialisation. PhD fellows do scientific research, often with conclusions that directly influence their region. At IHE Delft, PhD researchers from around the world participate in problem-focused and solution-oriented research on development issues, resulting in an inspiring research environment. PhD fellows work together with other researchers from many countries dealing with topics related to water and the environment.

PhD research is often carried out in the ‘sandwich’ model. Preparation and final reporting – the first and last portion of the programme – are carried out in Delft, while actual research is done in the fellow’s home country, under co-supervision of a local institute. Regular contacts with the promotor are maintained through visits and long-distance communication. This enables researchers to employ solutions directly to problems in their geographical region.

IHE Delft PhD degrees are awarded jointly with a university. The degrees are highly valued and fully recognised in all parts of the world.
