INTEWA UV units for disinfection of water

The UV  units are used for the sterilization of water. The UV light reliably inactivates pathogens and functions without the production of disinfection by-products. The UV lamps used are characterized by a long service life, high disinfecting perfomance and low energy consumption. The compact design allows easy removal and replacement of the lamps after expiry of their useful service life. For cleaning purposes, the quartz glass can be easily removed.

Electromagnetic spectrum

The low-pressure, mercury lamps operate in the UV-C spectrum at a wavelength of 254nm for effective virus disinfection.

  1. To properly dimension, first pick your application for the required radiation dosage.
  2. Determine the maximum flow rate for your application. This can be found with a pump curve (RAINMASTER or other pump).
  3. In the top row of the table you can find the appropriately sized UV units.

Safety precautions

The UV units should never be operated outside of the reactor chambers without special protective measures (UV-opaque safety clothing and protective eyewear)!

The possibility to save drinking water has enhanced strongly the last years.
