Many consumers saw the so-called water electrolysis experiments, all panicked: Is it really that dirty water?
To this end, the City Council special advisory director of Water Quality Monitoring Center Ltd. Foshan Water Group Huang Jianming. Huang Jianming said water becomes turbid phenomenon is a normal reaction of the electrolysis of water. Since calcium and magnesium ions in tap water containing iron bar genus electrolyte, anode electrolysis apparatus into the water, electrolyzed iron is dissolved in water, form a divalent iron ion (yellow-green), ferric hydroxide (gray) oxide iron (red-brown), tri-iron tetroxide (black); and pure water no conductive calcium and magnesium ions, the electrolytic reaction does not occur, so that pure water does not change color. In fact, water electrolysis experiment is not false, but sales personnel to the principle experiment distorted, misleading consumers, this is purely unscrupulous businessmen gimmick.

Huang Jianming also said that if there are additional requirements on the taste of water, and the like, commercially available household consumers can choose water treatment equipment, such equipment can achieve the effect of improving the taste.
