The product of the present invention can be widely applied to direct and potable water contact the surface such as water dispenser, water purifier, aqueduct and drinking water carries out the effect of bactericidal thus improving the sanitary standard of drinking water. May insure that the water that is stored in water butt because of the long period need not and not breed bacteria, it is therefore prevented that the pure water after purification is because leaving the secondary pollution formed in water butt in. Prior art generally utilizes the time to calculate for the service life of RO reverse osmosis membrane, and ignores RO reverse osmosis membrane self work because water quality, flow are used for the impact in life-span, generally changes RO reverse osmosis membrane by the cycle of 2-6 month. RO reverse osmosis membrane is higher as relative price in water purifier and the equipment that plays a major role, and such way generally has two problems, and one is that RO reverse osmosis membrane does not damage itself, and temporally changes the use cost adding user undoubtedly; Another one problem is that RO reverse osmosis membrane has damaged but also not to the replacement cycle, and now uses the water quality purified beyond doubt to go wrong and energy consumption increasing.
