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

Coagulant (a) Flocculant (b)
Both ferromagnetic and nonferromagnetic soilds are co-precipitated into flocs that can be picked up by the powerful ReMagDisc separator
