Stipulated according to People's Republic of China country standardGB10789-1996 that, the bottled tap water is refers to the seal tomodel in the glass jar, the glass jar or other vessels does notcontain any chemical additive may directly drink with the water.

1st, bottled tap water minute which how many kind?
(1) drinks with the native ore water seepage: Stems from theunderground deep place, includes a quota the mineral salt, the traceelement or the carbon dioxide gas, and is not the underground mineralwater which pollutes.
(2) drinks with the pure water: Take conforms to the life tap waterhealth standard water as the water source, uses ��, theelectrodialysis law, leaves �ӷ� or the ion exchange technique, thecounter- osmosis process and other suitable processing methods,removes water which processing and so on in water mineral substance,organic ingredient, deleterious substance and microorganism makes.
(3) other tap water: By conforms to life tap water health standardpicking from underground to form flows either is higher than thenatural water level to the surface water seepage the natural aqueousstratum blowout water seepage or the deep well water and so on thewater which results in for the water source processing system.

2nd, how does the pure water is invent?
In 1950, the American scientists observed in the sea the sea gull,could drink the highly concentrated salt the sea water survival. Afterthe research discovery, sea gull in vivo has an extremely thinmembrane, drinks into the sea water hydrone may seep the membrane,transforms the sea water as the fresh water, in the sea watersalinity, the impurity and so on cannot spit through the membrane�� outside. Because is opposite with the nature seepage direction,therefore calls the counter- seepage. According to this principle, in1953 the counter- seepage membrane developed successfully, the purewater only then was published.

3rd, what water is the distilled water?
The distilled water is through �� assumes the water heatingebullition the vaporization condition, then becomes the vaporcondensation the distilled water. The distilled water belongs to thepure water category.

4th, what water is the outer space water?
The outer space water is the American outer space bureau for theastronaut in the outer space work, life use Shui Er names. In order toreduce the spaceship carrying capacity, cannot the energy band be veryjuicy, only can has used the sewage, including the urine and so on��к the thing, process purification processing, becomes achieveddrinks with the standard resurgent water, the circulation use. Thiswas under the outer space special environment does not have alreadythe means, the spaceman returned to the Earth not to be able to drinkthis kind of water. But in the market sells "the outer space water",certainly is not circulates the resurgent water in the outer spacewhich the purification system results in, but is the ordinary waterthe pure water which through side legal system and so on counter- theseepage results in. Called "the outer space water" is the commercialname, basic has nothing to do with with the outer space.

5th, what the mineral water and do the pure water have to distinguish?
The pure water is take the river, the river, the lake water or therunning water and so on as a water source, uses ��, watertechnology and so on electrodialysis law, ion exchange technique,counter- osmosis process, had achieved the water is pure, the health,but while except bacterium and deleterious substance, also except tothe human body beneficial mineral substance and the trace element, haslost the potable water nutrition function.
The mineral water and the pure water common ground is the health, thesecurity, its different spot is, the mineral water is takes from theunderground deep place natural mineral water, includes a quota to thehuman body beneficial mineral substance and the trace element, thephysiological function is strong, has the health care function to thehuman body; The pure water except the mineral substance trace element,has lost the potable water nutrition function.

6th, what the mineral water and do the natural water seepage have todistinguish?
The shallow layer water which the natural water seepage is whichunderground gushes out in the water seepage or the mountain flows out,generally burial depth shallow, with underground rock layer contactduration short, the current capacity is unstable, is easy to pollute,also includes some to the human body beneficial mineral substance andthe trace element, but these characteristic component content, butalso has not achieved the mineral water the boundary target request,therefore cannot call it the native ore water seepage. The mineralwater includes the common water seepage deficient lithium, thestrontium, the selenium, the zinc, the idodine, the bromine, themolybdenum, the chromium and so on the trace element, has the healthcare function to the human body, is the common water seepage is unableto compare.
