Why SCIMEE Addicts to Rare-earth Permanent Magnets?

•  Strong magnetic force (640-fold of its weight)

•  Low decay rate (<5% in 10 years)

•  Green (Elicit magnetic force without consuming electricity)

•  Cost-effective (China is rich in rare earth minerals)

(1) Precipitate both dispersed and suspended solids into flocs by sequentially adding coagulants (a) & flocculants (b) in a 3-min process

(2) A ReMagDisc Separator continuously removes floating flocs without requirement of their settlement by gravity
