Apparatus for recovery of magnetic nanoparticles and apparatus and method for forward osmosis membrane filtration using the same

摘要

The present invention recovers magnetic nanoparticles that can separate and discharge high-purity treated water while maintaining a constant concentration of the induced solution by recovering and reusing magnetic nanoparticles in a forward osmosis membrane filtration process using magnetic nanoparticles as an inducing solute. Apparatus and a method and apparatus for forward osmosis membrane filtration using the same, the forward osmosis membrane filtration device using the magnetic nanoparticle recovery device according to the present invention is to concentrate the raw water and the treated water using the magnetic nanoparticles as the inducing solution of the induction solution Receiving the forward osmosis membrane unit separated by water and the diluted induction solution of the forward osmosis membrane unit, and injecting the magnetic nanoparticles into the diluted induction solution to adjust the concentration of the induction solution to induce the forward osmosis membrane unit. Induced solution concentration adjustment tank for supplying the induction solution to the solution tank and receiving the diluted induction solution from the induction solution concentration adjustment tank, And a magnetic nanoparticle recovery device for separating the pottery solution into magnetic nanoparticles and treated water, recovering the separated magnetic nanoparticles, and supplying the magnetic nanoparticles to the induction solution concentration adjusting tank.
