ELECTROLYSED WATER

Top of Document

There is a growing interest in special kinds of treated water with properties which differ from those of ordinary water. Electrolysed water is an example. Salty water is placed in a electrolytic tank divided into two by a diaphram. A weak electric current is passed through the water, between the cathode on one side of the diaphram and the electrode on the other.

The cathode water can be used to restore the quality of rice or soybean that has been stored too long and has deteriorated slightly. There have been reports that it prolongs the life of cut flowers, promotes the growth of plants and improves the health of livestock who use it as drinking water.

The anode water has strong bactericidal activity, and is being put to various kinds of medical use. Agricultural uses are also being studied. It is seen as a possible control of plant pathogens. Some studies suggest that spraying crops with anode water may help prevent disease. Another potential use being studied is the disinfection of rice seeds.
