Why are there many disgusting things after electrolyzed water in Jinan?

Because the water quality in Jinan is not very good, of course, unless it is spring water, tap water generally contains a lot of rust substances. When it decomposes, water contains hydrogen and oxygen, so we can see another separation in scale. That's what you call "disgusting things". Therefore, the water after the solution must be left for a period of time to precipitate before drinking, otherwise it will easily lose hair and yellow teeth.
