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.

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.

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
