  • Importance of measuring UV transmittance (UVT) for UV disinfection

    UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm. UV Disinfection Dose and UV Transmittance (UVT) The effectiveness of a UV disinfection system is ...

  • Development and evaluation of a small scale water disinfection system

    Provision of microbiologically safe drinking water for people living in the rural areas of developing countries remains a major challenge to date. A simple gravity-driven membrane point of use system was developed based on woven fabric microfiltration (WFMF) membranes. The WFMF is a loose type of membrane (0.45 μm). However, complete disinfection is not achieved with the WFMF, hence it was ...
