| Abstract: | In this research, the possibility of filtering nutrients out of the inlet water of Land van Maas en Waal is researched. In times of drought, more water needs to be let into Land van Maas en Waal. This water comes from rivers and canals and has a high nutrient concentration and contains a lot of algae. This lowquality water causes problems in Land van Maas en Waal because a high nutrient concentration and warm temperature are good circumstances for toxic blue-green algae to bloom. Making the water not safe for use. The research question is: What type of filter is most suited to remove the nutrients from the inlet water at the five inlet points in het Land van Maas en Waal? The research was performed by reviewing available literature and having interviews with experts of Waterschap Rivierenland. The filters have been compared with the use of a multi-criteria decision analysis. From the research, it became clear that a discontinuous sand filter would be the most suited filter for filtering inlet water, of the filters that have been analysed. While the filter is most suited for filtration and is deemed to be cost-effective more research needs to be done to see if filtering inlet water is a viable measure to improve the water quality and prevent algae blooms. |
