   The main purpose of a

microbial treatment of drinking water is to reduce, remove or inactivate all pathogens, to acceptable levels, despite the treatment of drinking water and to improve sanitation of public health intake is effective enough but sporadic cases of infectious diseases caused by water and point source outbreak, still appear from time. Drinking water may contain a wide variety of pathogens to humans or animals probably or definitely pathogenic, they damage the skin or through contact, inhalation, drinking, or exhaled, nose, ears, mouth, genital mucosa in direct contact with the eye endanger human health.

  

80 known natural water many possible pathogens, such as front Pseudomonas, Serratia, glandular bacteria, Bacillus pigment, Achromobacter, Aeromonas, etc., Bacillus coli, Enterobacter, Klebsiella, Actinomyces and Streptomyces spp or vegetables from door Xiang Wei: from time to time people rushed a body of water, which may soon enter the water plant pathogens can be attached to the water treatment equipment or the biofilm regrowth in the water distribution pipeline.

  

manure, sewage treatment and disposal system failure, or overload operation waterworks will not only cause water pollution, and can cause epidemics. Common outdoor activities such as swimming, boating, camping and water skiing, actors or swallowed by direct contact with contaminated water is suffering from enteritis, pharyngitis, folliculitis, go far ear induced disease risk among water, overcrowded parks and recreation can contaminate surface water and groundwater.

  

1985 to 1994, the United States due to the infectious diseases caused by contaminated drinking water outbreaks total of 21 times.

  

guarantee microbiological safety of drinking water is based on the barrier from the intake point to multiple users, prevent pollution and reduce the level without causing health hazards on. If including water resources and water conservation, proper selection and operation of a series of water distribution system contamination control measures to deal with a variety of barriers, security will increase. The preferred strategy is to focus on preventing or reducing the pathogen into the drinking water and reduce management method for removing pathogens rely on the water treatment process. Water should prevent contamination of human and animal waste as much as possible, because a lot of bacteria, viruses, protozoan parasites and pathogens that may contain. World Health Organization: Avoid drinking water do the potential impact of biological pollution on health, the most important is to control drinking water sources and water treatment work to do.

  

Microorganisms in largely changing rapidly, short occurring pathogensRelative peak periods may increase the risk of disease. And can lead to outbreaks of infectious diseases caused by water, for disinfection measures we can not rely solely on water quality management, but also need to tap water, even if the increase in the frequency of drinking water microbiological safety tests, based on a result of the lag, they can not predict signs of unsafe water quality.

  

above are taken from "Drinking Water and Management" Paez kitchen water, central water purifier, using the world patent "Golden filter media" technology, effectively removing harmful chlorine in tap water, heavy metals substances retain beneficial calcium and magnesium ions, the purified water weakly alkaline, more suitable for human consumption, without power machine, of the box, that the drink. Paez water purifiers, water treatment experts in the central and terminal, whole house water purifier brand of choice
