SUMMARY

This discussion centers on the feasibility of using magnetic fields to purify water for reuse in a CO2 scrubber project. Participants concluded that while moving charges in a magnetic field experience a Lorentz force, the forces involved are insufficient for practical desalination or purification. The consensus is that even with charged plates, the electric fields would not generate adequate force for effective water treatment. Established methods for water purification, such as deionization, are recommended instead.

PREREQUISITES
  • Understanding of Lorentz force and its implications in charged particle movement.
  • Basic knowledge of water chemistry, specifically ions like K+ and CO3-2.
  • Familiarity with electric and magnetic fields and their applications in purification processes.
  • Awareness of established water purification methods, particularly deionization.
NEXT STEPS
  • Research the principles of Lorentz force and its applications in fluid dynamics.
  • Explore the process of deionization and its effectiveness in water purification.
  • Investigate the use of electric fields in water treatment technologies.
  • Examine alternative methods for CO2 scrubbing and water reuse in industrial applications.
USEFUL FOR

Students, researchers, and engineers interested in water purification technologies, particularly those exploring innovative methods for CO2 scrubbing and water reuse.

I'm looking to make a CO2 scrubber for a school project and I was wondering if I can purify water to re-use it with magnetic fields. The ions would be K+ and CO3-2.

If this can be done can you explain what variables I have to look into to make sure it works, some variables I thought of was attration of ions and water, force of water flow, and the type of magnet used.

If you can give me your feedback and advice that would be great! Thanks!

Yes, but no.

Yes - moving charges in the magnetic field are shifted to sides (google for Lorentz force), no, forces acting on these charges are way too low to be used for practical desalination.
 
Is it possible to make the force great enough?
 
No, you won't be able to produce magnetic fields strong enough.
 
Ok what about positive and negatively charged plates?
