In the case of our present job, the strong alkali solution will be used locally to neutralise ,acidic wastewater, from other plants. Whatever process you use, somewhere you have to dispose of the salt. The solid residue remaining from pure chemicals is carbonaceous and slurried with oil that leaves as fuel, in our case to a controlled incinerator, who charges for the privilege.

More plates and power means the surface area the water has to spend in the ionization process is longer. Longer times in the chamber means that you will get a better pH spectrum on the alkaline and ,acidic, side PLUS increase the -ORP at drinkable pH levels (9.5 to 10.5 pH). More molecular ,hydrogen, is also produced at these beneficial pH levels.
