    The water source water in the environment through the purification Amway傳銷 water treatment plant to provide households, do you know, these meet the national testing standards water, in the household use, may also suffer secondary contamination, and thus bring risks to health, and household drinking water health risks mainly from microbial contamination.

    What high-risk stages of the household water process can lead to microbial secondary contamination?

    Inappropriate stages in the water supply process

    Leakage of the tap water network system: Due to the dilapidated water supply network, the network is damaged and the wastewater sludge etc. from the surrounding environment enters the water supply system, causing contamination of tap water.

    Cistern (tank) pollution: multi-storey buildings use roof tanks, cisterns or pressurized water pumps to carry out water supply, if these assistance equipment is not disinfected and maintained on time, there is usually a potential pollution problem.

    Siphoning backflow at the water point: When the main pipeline network is disconnected for some reason, and the pressurized pump is still running normally, the water in the wastewater tank will siphon backflow and flow into the short layer or neighboring building customers, causing pollution.

    Wrong connection of pipe network: For example, the wrong connection of sewage pipe and water pipe will lead to the waste water into the water pipe network.

    Improper application of home drinking fountains

    While the water dispenser is dispensing water, as the pressure inside the bucket decreases, gas will enter the dispenser and the bucket, and airborne microorganisms will live and breed in the bucket and the dispenser.

    Inappropriate stage in drinking habits

    Drinking cold water: Cold water, especially natural water, may contain bacteria, viruses and parasites that are harmful to humans. Drinking cool water containing microorganisms can easily cause acute gastroenteritis, viral hepatitis, typhoid, dysentery and parasitic diseases.

    Drinking water for a long time: water boiled, placed too long, the air microorganisms will enter theamway濾水器, so that the body of water suffered contamination.

    Barrel water contamination: some barrels of water overdue applications, and cleaning and disinfection is not in place, serious contamination in the barrel; barrels of water in transport, very few health safety measures, most outdoor transport, very vulnerable to external environmental pollution.

    Microbial removal methods

    The current approach to removing microorganisms from drinking water, there are two main chemical methods and physical methods.

    Chemical methods, that is, the traditional disinfection method, chlorination, ozone, heavy metal ionization method and other oxidant methods. Among them, chlorine is commonly used because of its strong disinfection ability, cheap price, easy chlorination equipment, convenient residual chlorine measurement, and easy quantitative adjustment; however, these disinfection solutions will have residuals in the water and produce halogenated hydrocarbons, which pose a threat to health. Ozone disinfection itself does not produce halogenated alkanes and total organic halogens, but other disinfection by-products such as aldehydes, ketones, and alcohols can produce trihalomethanes and Artistry評價 to health if chlorinated.

    The main physical disinfection methods are mechanical filtration, heating, radiation, microelectrolysis, ultraviolet light and microwave disinfection. Because of the advantages of strong sterilization effect, short disinfection time, no disinfection by-products, low cost, UV sterilization method is gradually becoming one of the miniaturized drinking water disinfection methods. However, UV sterilization must overcome some of its own defects: 1.

    1, the germicidal efficacy of UVC is not continuous, only effective during the irradiation period.

    2, suspended matter in the water will affect the effect of germicidal UVC.
