Wang, F. (author), Zhang, Lu (author), Wei, L. (author), van der Hoek, J.P. (author)During drinking water treatment, advanced oxidation process (AOP) with O3 and H2O2 may result in by-products, residual H2O2 and BrO3−. The water containing H2O2 and BrO3− often flows into subsequent granular activated carbon (GAC) filters. A concentrated H2O2 solution can be used as GAC modification reagent at 60 °C to improve its adsorption...journal article 2021

Zhou, Xinyan (author), Zheng, Huabao (author), van der Hoek, J.P. (author), Yu, Kefei (author), Cao, Yucheng (author)Large quantities of natural and synthetic hormones contained in livestock waste and wastewater (LWW) can cause serious problems in our environment. Composting and anaerobic digestion cannot remove hormones efficiently, so they should be modified to enhance the treatment processes. In addition, constructed wetlands show decent rates for...review 2021

Ahmad, J.I. (author), Dignum, Marco (author), Liu, G. (author), Medema, G.J. (author), van der Hoek, J.P. (author)Drinking water distribution systems (DWDSs) have been thoroughly studied, but the concept of thermal energy recovery from DWDSs is very new and has been conceptualized in the past few years. Cold recovery results in a temperature increase of the drinking water. Its effects on drinking water quality and biofilm development are unclear. Hence, we...journal article 2021
