In recent years ever-increasing amounts of pharmaceuticals are being detected in the aquatic environment and in some cases, they have even been discovered in drinking water. Their presence is attributed mainly to the inability of sewage treatment plants to ...
The operation of wastewater treatment plants is challenging for many small communities for economical and technical reasons. In this work, optimal control of the aeration system is considered to improve the efficiency and reliability of the activated sludg ...
The aim of this study was to characterize hospital effluents in investigating the CHUV importance as source of pollutants, the range and amounts of pharmaceuticals that are used in the hospital and the need of source treatment of the hospital sewage. The C ...
Aerobic granulation is considered as a promising alternative to conventional activated sludge in biological wastewater treatment. Instead of forming flocs the bacterial communities aggregate to dense granular biofilms. In the present study, granules were c ...
Pharmaceuticals and personal care products (PPCPs) represent pollutants of emerging concern, originating in surface and drinking waters largely from their persistence in wastewater effluent. Accordingly, a wealth of recent investigations has examined PPCP ...
Stabilization ponds and water lettuce-based systems in West and Central Africa - State of the art, removal performances and design criteria Despite several projects undertaken so far, sanitation remains a huge challenge in West and Central Africa. Big citi ...
The aerobic granular sludge process optimization is linked to the interdependence of process, biofilm and microbial scales. Stable dense fast-settling granules composed of bacterial guilds for the simultaneous removal of carbonaceous, phosphorous and nitro ...
Reverse osmosis (RO) concentrate samples were obtained from a RO-membrane system that uses effluents of wastewater treatment plants (WWTP) as feed water for the production of drinking water. A number of different pharmaceuticals (e.g. antibiotics, contrast ...
The use of dynamic optimisation methods to provide optimal operating strategies for small size wastewater treatment plants is investigated. The optimisation objective is to determine the aeration profile (air-on and air-off periods) which minimise the conc ...
