Plastic production is increasing yearly and so is the amount of discarded plastic. This contributes to the formation of microplastics. In the final thesis, we identified concentrations and sources of microplastics, presented different filtration methods, analyzed membrane filtration and different types of membranes, and identified the current best technology. We found out that the membranes removal efficiency is high but depends on the size and shape of the microplastic particles. Frequent replacement of the membranes is necessary, since they are subject to fouling and abrasion.
