Toelichting (Engels) This research was conducted during 01.02.2011 and 31.07.2011 in the SLIK (Sanitaire Lozingen Isala klinieken) project of Waterboard Groot Salland. The study was mainly to compare the effect of three water treatment methods in Parameters of wastewater treatments plant (WWTP). The wastewater sample came from the Isala Clinic in Zwolle, which was contaminated by pharmaceuticals, with an average inflow of 200 m3 per day. The designed flow for WWTP is 10m3/h. From the calculated concentrations at different sampling points (SP), elimination efficiencies show very different. Membrane bioreactor combined with results showed that MBR could filter most of 99 kinds of pharmaceutical compounds. Some compounds, for instance paracetamol is almost eliminated to 100%. But to eliminate the rest contaminations, UV/H2O2 and ozone techniques showed effective performance: UV disinfection is most effective for treating a high clarity purified reverse osmosis distilled water, but the wastewater flow rate can be neither too high nor too low; for the high flow rate water; Ozone has a very strong oxidizing power with a short reaction time, which is the more effective method for advanced step water treatment. Granular Activated carbon (GAC) serving as a post treatment eliminates most compounds completely or at a high rate.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
