How Does Ultraviolet Water Purification Work?

Chemicals are not introduced into the water so this lessens the possibility of chemicals posing harm to the human body. Ultraviolet water purification is a simple but effective process that destroys around 99.

These lamps emit nearly monochromatic UV radiation at a wavelength of 254 nm, which is in the optimum range for UV energy absorption by nucleic acids about 240-280 nm. We fetch water from the rivers or harvest from the rain in rural Kenya and store them in tanks of 50L, 100L, 200L.

Understanding UV Water Purification

See your local water specialist to discuss how this is done. UV disinfection is approved by the EPA, and is an environmentally-friendly disinfection method as it is a chemical-free process and creates no byproducts.

Significantly, UV rays are invisible to the naked eye. Because of the low pressure inside the lamp, it can emit radiation that is around 2537 A.

It is important to avoid drinking any water that is potentially contaminated from bacteria to protect yourself from any water-borne bacterial diseases. Last reviewed: UV technology does not remove any other contaminants from water such as heavy metals, salts, chlorine or man-made substances like petroleum products or pharmaceuticals.

This can easily result in situations where a malfunctioning or ineffective UV system continues to be used for extended periods of time. Class IIb. If a microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact.

Flow Rates in gpm. Aside from drinking water at homes, it is also used in untreated private water systems such as when camping. One of the biggest advantages of using a UV water purifier is that it is very cost effective at killing a majority of the harmful microbes associated with most common water-borne illnesses. March 22, 2011 at 7: Homeowner Water Testing. Any harmful microbes and bacteria that are present in the water are rendered sterile by the exposure to the germicidal radiation.

The UV light causes this glass to solarize and inhibits the transmission of UV light. Hardness in your water will cause possible scale formation on the lamp protecting the quartz sleeve.
