“…To this day, MSF has been implemented in the treatment of chemical mechanical polishing (Chin et al, 2006) as well as backside grind ing (Wan et al, 2011) wastewater and achieved excellent removal efficiencies when seed and target particles were oppositely charged. Electrostatic interactions also presented themselves as the driving force in the separation of organic dyes in wastewater (Fang et al, 2010). Furthermore, multiple studies showed that the removal of heavy metals can be accomplished in an efficient manner by MSF (Terashima et al, 1986;Karapinar, 2003).…”

h i g h l i g h t s Efficient removal strategies for microplastics are lacking. Magnetic seeded filtration showed high separation efficiencies ($95%) for dilute suspensions. Electrostatic interactions between particles were shown to be process determining. A parameter study identified relevant process variables and yielded clear application guidelines. The measurement of agglomeration kinetics enables further optimization.

“…They could reduce the turbidity of wastewater from paper factory lower than 60 NTU under 2 L/min of flow late. M. Fang [9] removed industrially used organic dyes with magnetic seeding by magnetic separation and got high separation efficiency. The results showed that electrostatic interaction is one of the main interactions between organic dye and ferromagnetic particles and the adsorption of organic dye can be controlled by removal of anion and adjustment of pH.…”

Superconducting High Gradient Magnetic Separation (HGMS) is widely used with its advantages of high separation efficiency, high processing speed, low-running cost and low-space requirements. The basic theory of superconducting HGMS and the applications of superconducting HGMS on environmental protection in recent years were discussed in this paper. Superconducting HGMS technology has shown a promising future.

We propose a magnetic separation system using superconducting bulk magnets to effectively separate organic dyes in wastewater. Two key technologies are applied in this system: magnetic seeding and magnetic separation. Magnetic activated carbons (MACs) are used to adsorb organic dyes Orange II and Crystal violet, which serve as magnetic seeds. We set up a magnetic separator by placing an acrylic pipe between the magnetic poles of a face-to-face superconducting bulk magnet for high gradient magnetic separation (HGMS) with the use of a stainless steel filter, composed of ferromagnetic wire stuffed into acrylic pipe. The experimental results show that the adsorption ratios of 99% and the separation ratios of over 97% were achieved at low flow rate for the organic dyes.
