51 Rui Ferreira Marta Frolova Haoyu Wang My name is Rui Ferreira and I am 22 years old. I come from Portugal and I am at TU Delft doing my Master Thesis in order to obtain the degree of Master in Environmental Engineering from Faculty of Engineering of University of Porto (Portugal). I am working at the Sanitary Engineering section of Faculty of Civil Engineering and Geosciences on Specic Methanogenic Activity and Phosphatase Activity of an anaerobic reactor used to treat the sludge resulting from marine Recirculation Aquaculture Systems. My research is supported by the project Emission Minimization of Marine Aquaculture Recirculation Systems (EM-MARES) carried out by PhD researcher Xuedong Zhang who is my daily supervisor . I am also being supervised by professor Mark van Loodsrecht and Dr. Ir. Henri Spanjers. I was born in 1990, in Rezekne, that is a town on the East of Latvia (one of the most beautiful countries in the world). I am studying in the 4th year out of 5 in Riga Technical University in the bachelor study program Heat, Gas and Water Technology in the faculty of Civil Engineering. I have been studying in Norwegian University of Science and Technology as an exchange student in autumn 2010 and this year came to Delft for an internship for a time period 20.02.2012 – 20.08.2012. Here I work together with Ran Shang and my topic is “Rejection of EfOM and ions from WWTP efuent water by back-washable ceramic tight UF membranes (BCNF)”. I really like this nice city and all the people around. Hopefully this will be an interesting and productive 6 months and I will learn many new things. Research exchange I was born in 1985 in the city of Harbin, which is named as “Pearl on the swan’s neck” in China. Both my bachelor degree (2008) and master degree (2010) were gotten at the major of Environmental Science and Engineering from Harbin Institute of Technology (HIT). Now I am a PhD candidate at State Key Laboratory of Urban Water Resource & Environment at HIT. Sponsored by Chinese Scholarship Council (CSC), I started working at the Sanitary Engineering section of UNESCO-IHE as a PhD researcher for two years from December 2011. Since this February I started doing research at TU Delft for several months. At TU Delft, I join in a project which focuses on wastewater treatment by using EGSB system, cooperating with DSM. My previous studies were about microbial fuel cell (MFC) and microbial electrolysis cell (MEC). I like yoga very much. Moreover , I like playing chess and enjoying movie. I got married in the summer of 2011 and my husband Yu Tao is also a PhD researcher at the Sanitary Engineering section of TU Delft. I am an Associate Professor in the Department of Civil and Environmental Engineering at the University of Auckland (UoA) in New Zealand and am visiting TU Delft for a period of 5 months (February to June) as a part of my Sabbatical leave. During this time I will be working on the “Emerging substances: Towards an absolute barrier (ESTAB)” project. This area overlaps with the investigation of fate, transport, and impact of endocrine disrupting chemicals (EDCs) and pharmaceutical and personal care products (PPCPs) being carried out by me research group. Funding for my visit to TU has been provided by De Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO) via a “visitors” grant to Prof. Jan Peter van der Hoek. Naresh Singhal
