This so-called magnetic flocculation can provide easier separation due to larger magnetic forces compared to the effect of the Stoke's drag force and Brownian motion; furthermore, this larger force also results in easier filtration due to the larger size of aggregates compared to single particles (Schwaminger et al., 2019b). The drawback is ...
