Here is plasma reactor + active carbon filter  for perfect disinfection of all bacteria and removal of heavy metals and arsenic  in the under ground water .. and no chemical, no ozone, no RO,
simple to use .. physical treatment......  http://bbnworld.net/water/awp15_techdoc.pdf 

The plasma high voltage pulsed discharge is induced directly in the effluent stream generating multiple oxidants and radicals such as OH, O, H, O3, H2O2, etc.

Such aggressive oxidant species are nonselective and oxidize all contaminants in the effluent. A high intensity UV light released during the process is used for bacteria disinfection. 

The price is USD7500 and delivery by FeDex  within a month. bbn@bbnworld.com  Frank Choi
