The water is the source of the life.Along with life the exaltation of the level, people of life is changing toward the middle-class family type from WEN BAO3 XING2.Improve the drinking quantity is already the urgent target that large people's crowd pursue, is in recent years particularly, the drinking water consume to have already been accept by many citizenry, consuming the market more and more big, the market competition is also very vigorous.But each kind of waters all have it each from of characteristics.What water should to know drink, should have to each kind of water a probably of understanding.Underneath, introduce toward everyone once a few main drinking water that promote on the market currently:

Drink the purified water drinks the purified water with match the water of the living drinking water health standard as headwaters, adopt to distil the method, the electricity seep method, ion exchange method, anti- permeate the method and other appropriately process method do away with the water that the aquatic mineral quality, organic composition, harmful material and microorganism etc. processes to make into.According to process the craft dissimilarity, drink the purified water to also be called the distilled water, pure water of the water, space...etc., is main product of the drinking water market.The above drinking water of 90% produces the business enterprises to all produce the purified water.The purified water fluid matter is pure, transparent, eating good.Because the purified water has no the mineral quality, the fluid matter be partial to sour, so be the life to the purified water in the only one drinking water to the human body health whether have the influence, have been topic that expert issue.

Drink the natural mineral spring drink natural mineral spring is gush from a nature of or was make public by artificial of did not be subjected to polluting of underground mineral water, imply the certain quantity mineral salt, little chemical element or the carbon dioxide airs, under the condition of usually, its chemistry composition, discharge, water temperature etc. the dynamic state is within the scope of natural motion opposite stability.The mineral spring implies the more mineral quality, the some and particular chemical element has the function of health care to the human body healthily.The mineral spring of the region of Shanghai takes out from the deep well, to enrich the mineral spring with Strontium(Sr) and be partial to Si sour is characteristic.Because groundwater of Shanghai in the ion of Na , the chlorine ion content is higher, the aqueous degree of hardness is also high at the same time, making the eating of the mineral spring been partial to up salty, if heat the boiling words, will still produce the mineral quality to precipitate, the fluid matter appears the muddy, can't make some consumers accept.

Mineral quality water

The mineral quality water increases a little amount mineral to turn the chemical element to make into on the purified water foundation.The emergence of that type of water mainly aims at the purified water not to contain the mineral quality and drink over a long period of time healthy to the human body disadvantageous this ory breaks but develops.Along with the turn worse of issue, the type's water contain the trend of the further extension.In recent years, have not a few purified waters production business enterprise to produce the mineral quality water at the same time, with the orientation the dissimilarity consumes the demand of the community.But have no nation the standard because of the mineral quality water, its quantity is only ability from business enterprise oneself establishment the business enterprise standard to control.But the mineral quality water that different business enterprise produce, its mineral turns the chemical element category different from contents are all.Some business enterprises even add the chemistry to try in the water directly, the concentrated liquid of the business enterprise usage background unidentified mineral quality that also have, these safeties and usefulnesseses that increase the material did not carry on the argument, content of how much also have no science according to.

The spring water( natural water) Shanghai is on the market the spring water( or call the natural water) of the sale is draw from the river, Guang on taking to pollute the less of river, lake in or the water of the underground, filter through depth, make into after disinfecting the processing.This water implies one mineral quality of the fixed amount, but the content is is low in the mineral spring, can not reach the index sign of the mineral spring national standard provision, so nothing of is a mineral spring.And among them some minerals quality content is also unsteady.In addition to local business enterprise directly selling in Shanghai, these waters are mostly after Shanghai produce the business enterprise to entrust the region to infuse to pack, the above sea produces the name of the business enterprise to carry on the sale.This water because of producing the place in the another province City, Shanghai City don't as to it's the execution allows to produce the certificate management and directs to make selective check.The product quantity mainly from produce the business enterprise to request to carry on the control according to the business enterprise standard.

The choice of the drinking water of ¡î

Choose and use the drinking water, should notice following several aspectses:

1.Whether check a cover of the hogshead water seal completely or not.A cover does not seal completely, the water is easily pollute by germs.Especially in summer, the bucket covers the easy occurrence to loosen to move.Can try to revolve a cover by hand, see a cover can turn to move.Or pour bucket put in a short while, whether an of observation has the exudation of water or not.Explain the bucket that the cover does not seal completely if have the exudation of water,,.

2.Whether fluid matter in the careful observation bucket is clear or not, whether suspend the thing.Explain that the fluid matter is subjected to the pollution if discover to have already suspended the thing, foreign body or s in the water in the bucket muddy,,, can't drink.

3.Choose a water for pack as far as possible, an usage time is long, will slip not only inside the wall, depositting the bucket of the mineral spring especially, producing the mineral quality to precipitate easily inside the wall, not easy and pure clean, will stir up the germs.Observe a wall, can't appear the green weed.Discover the green weed, explain the water already drive the microorganism pollution, can't drink again.

4.Taste a water.The normal water should have each each kind of water from the normal eating, sometimes there will be the slight ozone flavor, this is normal.Can't drink again if have other strange smells or the plastics flavor,,.

5.Notice the date of production of product, drink the product produce in the near future possibly.Once a Kaifeng drink, should drink to finish as soon as possible.General on board barrel water in the drinking, drink to expect shouldn't over a week, otherwise, fluid matter easily be subjected to the air the pollution of the germs.

6.The Water Drinking Machine should place in clean and well ventilated environment.Periodically use to disinfect the liquid to clean the disinfection, assurance Water Drinking Machine hygiene.The mineral spring and spring waters should keep at cool, avoid the light, avoid the sunlight irradiation.Because under the function of the sunlight, alga will breed quickly, causing green weed appear.

The main technique request of the drinking water

Drink the national standard of purified water difference for GB17323-1998 ¡¶ bottle packs to drink the purified water ¡· and GB17324-1998 ¡¶ bottle packs to drink the purified water hygiene standard ¡· .All ruled the sense organs index sign, the physics and chemistry index sign and microorganism index signs in those two standards.

Feeling view index sign:The sense organs index sign includes the color degree, muddy degree, smelly and flavor, and can see without the aid of instruments 4 of thing, is basic request of the purified water.The color degree should not over 5 degrees, and can not have other different colors;The muddy degree is not over one degree;The just like flavor, the difference is smelly and can see without the aid of instruments the thing.

PH value:The pH value is to mean the aquatic and sour alkalinity.The purified water produces because of producing the craft reason of water be partial to the acidity.The pH value scope is in 5.0~7.0.

Electric conductivity rate:The electric conductivity rate means the pure degree of the purified water, is the characteristic index sign of the purified water.The electric conductivity rate is more low, explaining the water more pure, the miscellaneous quality in water is more little.The electric conductivity rate is in the standard provision purified water should 10 ¦Ì S/ cms of ¡Ü .

The high potassium manganate consumes the quantity:The high potassium manganate depletion quantity mean the 1 L water in the revivification material the oxygen milligram that consume while was under certain condition oxidize by the high potassium manganate number, the content of the organic compound in its main reflection water.The high potassium manganate consumes the quantity more low, elucidation the organic compound in water is little, pollute little.Some disinfection liquids remain and also will make the high potassium manganate consume the quantity to increase high.The high potassium manganate consumes in the purified water quantity should 1.0 mgs/ l of ¡Ü .

Swim to leave the chlorine: pure aquatic mainly swim to leave the chlorine is the bucket cleans the ill success, making contain the chlorine disinfection liquid to remain to resulted in chemistry pollute in the water.Standard the provision swims to leave chlorine should 0.005 mgs/ L of ¡Ü .

Lead, arsenic, copper:The lead, arsenic, copper is the harmful metals chemical element, will result in hurt to the human body health, should be more low in the water more good.Standard provision lead ¡Ü 0.01 mgs/ L, arsenic ¡Ü 0.01 mgs/ L, copper ¡Ü 1 mg/ L.

The germ falls the total amount:The pure and aquatic germ fall total amount is express that the purified water be subjected to to the pollution extent of marking.Standard provision, the germ falls in the purified water total amount should 20 cfus/ ml of ¡Ü .

Coliform:The main source of the coliforms is a person the raise excrement, so that index sign is the excrement pollution index sign to evaluate the health quantity of the purified water.Standard provision purified water in coliform should 3 MPNs/100 mls of ¡Ü .

With the result that germ:With the result that the germ means and would cause mankind the paroxysm germs, is mainly a surname germ, ambition congratulate surname germ, golden color staphylococcus of sand and dissolve the guts streptococci in the food.Can not check in the standard provision purified water with the result that germ.

Fungi:Pure and aquatic fungi mainly is be subjected to produce the environment in the fungi of pollution or bucket don't be pure to clean to result in after are open-air deposit the pollution.The fungi will produce the toxin, resulting in endanger to the human body healthily.Standard provision purified water in can not check a fungi.
