Removal of plant pathogenic bacteria during agricultural managed aquifer recharge to produce irrigation water and protect plant health

Fresh water is an essential resource for life. Yet, overexploitation of water resources, rainfall shortages, and a decrease in water quality by pollution increase water scarcity worldwide. Since agricultural production consumes about 70% of the available fresh water resources, it is particularly vulnerable for water scarcity. Therefore, this...

The contribution of deeper layers in slow sand filters to pathogens removal

Slow Sand Filtration is popular in drinking water treatment for the removal of a wide range of contaminants (e.g., particles, organic matter, and microorganisms). The Schmutzdecke in slow sand filters (SSFs) is known to be essential for pathogen removal, however, this layer is also responsible for increased head loss. Since the role of deeper...

Removal of bacterial and viral indicator organisms in full-scale aerobic granular sludge and conventional activated sludge systems

The aim of this study was to evaluate the effectiveness of the novel aerobic granular sludge (AGS) wastewater treatment technology in removing faecal indicator organisms (FIOs) compared to the conventional activated sludge (CAS) treatment system. The work was carried out at two full-scale wastewater treatment plants (WWTP) in the Netherlands,...
