van den Brand, Tessa (author), Snip, Laura (author), Palmen, Luc (author), Weij, Paul (author), Sipma, Jan (author), van Loosdrecht, Mark C.M. (author)The application of sulfate reducing bacteria (SRB) to treat municipal wastewater is seldom considered. For instance, due to low sludge yield it can reduce the amount of excess sludge produced significantly. Several studies, mainly at laboratory-scale, revealed that SRB can proliferate in artificial wastewater systems at temperatures of 20°C...journal article 2018

(author), Brdjanovic, Damir (author)The concentration of sulphate present in wastewater can vary from 10 to 500 mg SO<sub>4</sub> <sup>2−</sup>/L. During anaerobic conditions, sulphate is reduced to sulphide by sulphate-reducing bacteria (SRB). Sulphide generation is undesired in wastewater treatment plants (WWTPs). Previous research indicated that SRB are inhibited by the...journal article 2017

Zahmatkesh, M. (author), Spanjers, H. (author), van Lier, J.B. (author)In this study, we tested a new approach to facilitate the application of white rot fungi (WRF) under non-sterile conditions, by introducing grain sorghum as carrier and sole carbon and nutrient source for WRF. To this end, Trametes versicolor was immobilized on sorghum, and its ability to remove humic acid (HA) from synthetic and real...journal article 2017

Hu, J. (author)In the recent years, the removal of micro-pollutants from treated wastewater has been highly advocated throughout Europe and the rest of the world. The relevant regulations and the suitable techniques have been proposed accordingly, which promoted the innovation of the conventional wastewater treatment plants (WWTPs). Activated carbon adsorption...doctoral thesis 2016

Van den Brand, T.P.H. (author)The depletion of fresh water sources forces to design innovative integral solutions for the urban water cycle. Usual practice in most cities is to use drinking water to transport waste outside the city via sewer system. For toilet flushing the water quality is less important and seawater could be used as alternative to use of drinking water. Due...doctoral thesis 2014
