Direct membrane filtration of municipal wastewater in Norway

Real raw municipal wastewater is treated abiotic in combination of chemical and mechanical treatment with microfiltration as the final treatment step. This rather new treatment concept is described as direct membrane filtration and has been tested in a smaller scale in Sweden. The presented concept in this study is significantly larger (386 times) and is built in Norway to compare both studies performed in Sweden and Norway. The expected outcome is high carbon and phosphorus removal which makes it very interesting for wastewater treatment in the Norwegian but also European ( 99 % removal of microplastics which is a world-wide hot topic. The presented direct membrane filtration concept is claimed to be the largest tested concept within Scandinavia. (Less)
