Description

Metal contamination in the environment is a persisting global issue. The metal reservoirs in the earth have declined due to society’s needs and due to uncontrolled mining activities. Therefore, the idea to recover metals from waste streams has emerged.

In this thesis, cost competitive technologies such as adsorption using agro-wastes and precipitation using an inverse fluidized bed (IFB) reactor were investigated, with special emphasis on the recovery of base metals. Groundnut shell showed good potential for metal (Cu, Pb and Zn) removal. From artificial neural network modeling, the performance of the sulfate reducing bacteria (SRB) was found to be strongly pH dependent; the removal efficiency of Cu and Zn in the IFB at pH 5.0 was >97%. Electronic waste is a good candidate as secondary metal resource. The recovery of Cu from computer printed circuited boards (PCBs) using biogenic sulfide precipitation was investigated as well. Using this technology, Cu could be recovered at ~0.48 g Cu/g PCBs.

About the Author

Suthee Janyasuthiwong was born in 1986 in Bangkok (Thailand). He obtained his diploma in Bachelor of Science in Biology (Botany) in 2008 from Kasetsart University (Bangkok, Thailand) with second class honors under the fellowship from Science Achievement Scholarship of Thailand (SAST) by the Human Resource Development in Science Project. From 2008 to 2010, he pursued his post graduate study with specialization in Environmental Technology Toxicology and Management. This is a collaboration between the Chulabhorn Research Institute (CRI), Mahidol University (MU) and Asian Institute of Technology (AIT) under the fund from the S&T Postgraduate Education and Research Development Office (PERDO) and Royal Thai Government fellowship. From November 2011, he started his doctoral degree with the joint doctorate program supported by the Erasmus Mundus Joint Doctorate in Environmental Technologies for Contaminated Solids, Solis, and Sediments (ETeCoS3). His research was mainly carried out at UNESCO-IHE Institute for Water Education (The Netherlands), and partly at the University of Cassino and Southern Lazio (Italy). The main focus of Janyasuthiwong's research was on metal removal and recovery from waste streams.

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.
