What are the harmful substances in the water?
People say, “a drop of water is a world”. Even if it looks very “clean” water, also contains a variety of substances. For people’s health, there may be a number of harmful substances. First, toxic inorganic substances, such as mercury, lead, arsenic and nitrite and so on. Second, pathogenic bacteria. Third, some of the toxins secreted by algae. These substances are often natural, often said the “water quality” often depends on the content of these ingredients.
Human beings “make” all kinds of carcinogens in order to sterilization
Pathogenic bacteria can produce immediate harm to the human body, so the water for sterilization treatment has become a regular step in drinking water. For tap water, chlorine or hypochlorite treatment is often used. This is a very significant means of sterilization, for reducing the disease caused by pathogenic bacteria has a significant effect. However, it was later discovered that this treatment produced a by-product, there are a number of carcinogenic. So scientists have been looking for ways to be able to have a relatively small treatment, such as the ozone treatment for bottled water, for example, is a relatively good way to deal with it. But its by-products bromate is also a possible human carcinogen. At present already tried or are trying to water treatment, there have been dozens of disinfection by-products to be pulled out.
The table list of harmful substances:
|Not soluble in water||Suspended solids||Sediment, rust||Excessive iron content, long-term drinking will increase the burden on the kidneys, resulting in endocrine disorders, high blood pressure, etc.|
|Pathogenic||Giardia, Cryptosporidium||Disease vector, can cause diarrhea, dysentery, typhoid, cholera, etc.|
|Bacteria||Escherichia coli, Staphylococcus, mould|
|Viruses||Norwark virus, spiral virus|
|Soluble in water||Nitrate, nitrite||Nitrite poisoning, carcinogenic|
|Disinfection by products||Halogenated hydrocarbon||carcinogenic|
|Natural organic matter||Humus, protein, lipids etc.||Most of the decomposition, the impact of turbidity, odor|
|Artificial organic matter||Formaldehyde, pesticide||Endocrine disorder, can cause cancer, malformation|
|Inorganic ions||Arsenic, fluoride||Will accumulate in the body, not easy to discharge, there are mutagenic, carcinogenic, and malformation|
|heavy metal ion||Lead, cadmium, chromium, mercury|
General size of the harmful substances:
Sediment, rust: 50 micron
Bacteria: 0.5 micron
Viruses: 0.02 micron
Heavy metal ion: 0.005 micron.
Now you know the kinds of harmful substances and the features, so should make great attentions to the filtration mode of the filter or purifier, get the good result as you wish.
