The advantages and disadvantages of UV Sterilizer
1.Advantages of UV sterilizer
Effective – Destroys 99.99% of microorganisms
Chemical free – no harmful chemicals need to be added
Environmentally Friendly –Go green! UV is an environmentally friendly alternative to chlorine disinfection and has no disinfection byproducts
Essentially trouble-free – once installed, annual service is usually all that is required
Reliable – works night and day, 24/7, consistently keeping water safe
Safe – no handling of chemicals
Cost-Effective –only lamp & sleeve replaced annually
Clean – no dirty parts to dispose of
Quick Process – water flows through the system without need for holding tank or reaction times
More effective than chlorine or chloramines – especially on some water borne cysts
Low energy usage – low electrical needs
FDA Approved – one of only 4 methods approved for disinfection by US Food & Drug Administration (FDA)
Conserves water – The UV purification process does not waste any water
Taste and odor – Chemical disinfection methods (such as chlorine) change the taste & odor of water and produce byproducts. UV does not.
Most ultraviolet water treatment systems require only an annual change of lamp – as simple as changing a light bulb – and a periodic change of a Filter cartridge that protects the lamp. Although the initial cost of some UV applications are a bit more than chlorination, the low operating costs make it pay for itself in no time.
2. Disadvantages Of Ultraviolet Water Purification
While there are many advantages of UV water treatment, some attention must be paid to the challenges it poses.
UV light is only able to eliminate microorganisms in water. 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. Other filtration methods should be employed with UV to ensure that all contaminants are removed from the water.
UV water systems need electricity to operate. A UV may not be suitable for all applications such as rural, emergency needs or survival needs if electricity is not available.
UV light is only able to work if water is clear. If the water is murky or contains [floaties," a pre-filter should be used; UV light cannot effectively reach microorganisms because the rays are blocked by the other particles.
Overall, UV water treatment is an outstanding way to meet your water purification needs. UV has proven to be one of the most reliable, quick, and cost-effective methods for disinfecting water at both point-of-use (kitchen tap) and point-of-entry (whole-house) applications.
