Weak Alkaline Electrolysis is not really used in the west but it is still around in China and Japan. In Chinese with English abstract: “A system of alkalizing water comprising electrolytes in ionic form. Weak alkaline electrolysis uses rare gases (such as oxygen, nitrogen, argon, etc.) and / or metal ions to excite water using an electrolysis cell.” That’s about all the information I have on this subject. I do not know if it is useful for disinfection or not, but it does have a weird sound to it when you explain it to a friend.
This type of water purification system has a couple of advantages. First of all, the main limiting factor is that you must use a strong current. If your water is strong enough to pass through the top of the container where the galvanized object lies, you can then use a much smaller second coil as the part of the current path that goes through the top of the container, and it just so happens. that the current from the galvanized object passes through the small gap between the two coils. Thus the current you are using is very high frequency. Theoretically, you could get away with a low-frequency electrical current, but there is the problem of destroying your galvanized object if you do not protect it properly.
That brings me to my last major point. If the food control level in your area is not too high, you may want to consider using an Electrochemical approach to food control. The idea of this approach is to use a low-frequency electrical current to destroy the microorganisms responsible for most disease problems. Thus, the theory goes that by controlling the environment and doing away with the food supply, we can return the microorganisms to a state of normalcy. There are many patents filed on this technology, and it has been embraced by some of the big names in the food control industry.
