Magnetic separation and transfer of wastewater contaminants using magnetic travelling wave and micro magnetic bead

Water treatment technologies have been developed to purify wastewater containing contaminants much and efficiently. In a typical chemical method, reagent and polymer material are added to the wastewater in a stirring process and then the contaminants in the wastewater form flocculation by the chemical additive. The formed flocculation sinks to the bottom of precipitation tank by gravity. In this process, a huge precipitation tank and a long process time are needed. Furthermore, the addition of the chemicals requires much cost, and can be also another source of environmental problems.
