UV Disinfection Technology for Water Treatment

Posted on April 3, 2019 UV Disinfection Technology for Water Treatment

UV Water Disinfection Technology

In  UV water disinfection technology, Ultraviolet light of wavelength 253.7 nanometers is used for disinfection of bacteria, viruses, molds, algae, and other microorganisms, which multiply and grow.  UV disinfection technology destroys the DNA of microorganisms which leaves them dead and unable to grow further. UV disinfection technology can be used for drinking water disinfection, process water disinfection, wastewater disinfection, and surface disinfection. Other than disinfection applications, this technology can also be used for TOC removal and Ozone destruction.

Effective – All known microorganisms are susceptible to UV light

Economical – Lowest operating cost amongst disinfection systems

Safe& Chemical Free – No addition of chemicals hence no danger of overdosing

Fast – It is on-contact purification &  therefore Instant

Easy to Manage – Well designed systems like the Alfaa UV disinfection systems come with many advanced features like CFD (Computational Fluid Dynamics), high-efficiency electronic ballasts, and extremely precise UV intensity monitors which make them highly effective and easy to manage.

Maintenance of UV Disinfection Systems:

There may be some cases where the water is not adequately pre-treated and turbidity levels are higher than desired. In such cases, routine inspection and cleaning can be carried out every 6 months. In the case of high turbidity and hardness, the cleaning frequency might need to be increased. Finally, the UV lamp has a limited life and must be replaced once it is exhausted. In the unlikely event of premature failure of the lamp, the monitoring circuit will provide the signal to advise replacement.
