flocculants - an overview | sciencedirect topics

Polymers can be combined with magnetoresponsive Fe 3 O 4 nanoparticles to separate the flocculated microalgae from the medium in a magnetic field (Lee et al., 2013; Lim et al., 2012; Xu et al., 2011). This magnetic separation is a faster method to separate the flocs from the medium than gravity sedimentation or flotation
