Hello, I'm a chemical engineer working in the shipping industry. In a few words,there are many technologies emerging lately due to a new Marine convention that forces all vessels to treat ballast water (disinfection) before discharging it in order to minimize consequences from the mix of different sea ecosystems. One Korean system uses a combination of filtering, UV radiation and Plasma shockwaves to achieve the necessary levels of disinfection. My problem is i don't have the necessary knowledge to understand how this Plasma system works. I would like someone to take a few mins to read through the subject and explain to me how this sytem works. Here is a link describing this system : http://mykomec.blogspot.gr/2012/04/ara-plasma-ballast-water-treatment.html I'm looking forward to your replies. Thank you in advance. PS.Excuse my flawed English, i am Greek PS1. Feel free to move this thread to a more suited section, if there is one. I understand this is not a ''typical'' engineering question.
