UV Water Purification

When to replace the Ultra Light bulb

How often should I replace my UV bulb?

That’s a good question. You see, many manufacturers recommend to replace your uv bulb once every 12 months of continuous use. However, it really depends on the condition and specific unit in question.

Although the ultra-violet bulb appears to be in working condition, that is you see it emitting visible light, it still may not be good enough to emit at the required 254nm wavelength; therefore it’s advisable not to rely on a simple visual test.

In addition to the above, you may wish to clean the glass whenever you are replacing the bulb since any blockage might impair the effectiveness of the UV light, resulting in a ultra violet malfunction.


Chlorine Vs. UV Ultraviolet Water Purification

Major soft drinks groups use Ultra Violet disinfection to provide micro-biologically pure water, which helps add shelf life to their products. Soft drinks and bottled water producers build their reputations around the purity of their products, emphasizing the fact that they’re natural.
