Direct membrane filtration of municipal wastewater in Norway
AI summary Read the abstract
This Norwegian study tested a large-scale direct membrane filtration system for treating raw municipal wastewater, combining chemical and mechanical treatment with microfiltration as the final step. The approach is notable for its potential to remove more than 99% of microplastics while achieving energy-neutral operation through high carbon capture.
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 (< 10 000 PE) perspective. Furthermore, the concepts potential is to treat wastewater energy neutral due to high carbon rejection and a Finish study showed high >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.

Treating wastewater for microplastics to a level on par with nearby marine waters
AI summary Read the abstract
Researchers studied microplastic removal at one of Sweden's most advanced wastewater treatment plants and found that it achieved a 99.98% removal rate, bringing discharge concentrations down to levels comparable to the surrounding marine waters. The mechanical pre-treatment stage was responsible for the largest share of removal, with activated sludge acting as the main collection point for captured particles. The study demonstrates that well-designed modern treatment plants do not have to be significant sources of microplastic pollution.
