　　The human body is the relatively stable, and it is in the alkalescence. Our body fluid should be in alkalescence, and the PH value is 7.35-7.45, which can keep the normal physiological function and metabolism.

　　It is self-evident that water can keep the acid-base balance of our body fluid, because water can be absorbed by the digestive system directly, then enters into the body fluid. The drinking water experts suggest that: if the PH value of drinking water is close to that of human healthy blood, it is the best.(PH value should be 7.35-7.45)

　　Which kinds of water are acidic?

　　The PH value of water is up to the dissolved mineral elements and gas in the water. Generally speaking, the urban tap water is as the raw water, then the production water is the acidic water. Such as pure water(or ultrapure water, distilled water), we add acidic mineralized solution into mineral water which is on the basis of acidic pure water, such as magnesium sulfate, the mineral water will be more acidic than pure water.

　　Which kinds of water are alkalescent?

　　The natural water from high quality water source is usually alkalescent, PH value is about 7.3, including the necessary mineral substances and microelements for human body, such as potassium, calcium, sodium, magnesium and metasilicic acid and so on, the types and contents are in the overall and balanced condition, which conform with the needs of human body, which also can maintain the acid-base of body fluid.

　　Life tips: how to choose the healthy drinking water?

　　Three keys of healthy water:

　　1. No-pollution, free of pathogenic bacterium, heavy metal and harmful chemical substances, moderate hardness;

　　2. Including the necessary natural mineral substances and microelements for human body;

　　3. Small molecule of water, which is alkalescent.

　　Applications of ultrafiltration technology: early industrial ultrafiltration was applied to sewage and waste water treatment. In recent 30 years, with the development of ultrafiltration technology, the application fields of ultrafiltration membrane has been widely used in many industries: including food, beverage, dairy, biological fermentation, biomedical, pharmaceutical chemicals, biological preparation, Chinese medicine preparation, clinical medicine, printing and dyeing sewage, food industry waste water treatment equipment, resource recovery and environmental engineering and so on.

　　Small-scale pre-filter, it is usually installed after inlet pipeline meter, in order to prevent human body from harm of much precipitation contamination, and protect the concealed pipeline, spigot, apparatus actively. Pre-filter is the bane of second pollution, which is the reliable contamination filtration device.

　　Characteristics and effects

　　Remove the visible solid impurities and some harmful chemicals in the pipeline, mainly including iron rust, mud and sand, algae, colloid and so on, protect the pipeline, spigot, apparatus actively.

　　Once the impurities without pre-filtration enter into the pipeline, what the dangers to human body will be. Pipeline and other relevant water equipments(such as washing machine, dish-washing machine, water softener, water purifier and water heater etc.) maybe damaged, even destroyed completely. We have to change the relevant valves, joints and filter screen. That is why Germany issued the above injunctions in 1988, thus which avoid a lot of unnecessary maintenance and cost. In Germany, the law prescribes that every family should install the pre-filter(after inlet pipeline water) to ensure that the large amount of contamination impurities in the pipeline network won’t do harm to human body, and protect the concealed pipeline, spigot, apparatus and so on actively. Pre-filter is the bane of second pollution, which is a reliable impurities filtration device. The aperture is between DN20-DN32, which can filter the impurity particles of 5-120 mm, which can make water quality reach the factory standard. The pre-filter with reducing valve can make the feedwater pressure constantly, in order to eliminate the noise of water hammer and the damage of pipeline brought from the sharp change of water pressure, meanwhile, which can save a lot of water cost. It is suitable for households and independent device, for examples: water purifier, dish-washing machine, dentistry treatment system, water heating device, agricultural irrigation(such as micro-irrigation, drop-irrigation system and pre-filtration) and so on, which can remove the pollution and avoid the pipeline rusting.
