  • The Best Ground Water Treatment Methods

    Many homes and businesses depend on ground water or surface water as a vital water source. Unfortunately, much of this water has not been filtered through municipal water treatment and distribution technology. This means that the water many people consume, cook with, and use for basic hygiene can contain potentially harmful particles, including pathogens, tiny organic matter, sediment, ...

  • UV Minimises Risks for Major Food Retailers

  • A computational fluid dynamics analysis of placing UV reactors in series

    Ultraviolet (UV) light water treatment reactors are commonly used in both wastewater and drinking water disinfection. UV technology can effectively inactivate a large number of pathogens at low UV doses, however adenovirus requires a substantially higher dose than most pathogens of interest. In order to meet adenovirus inactivation requirements, UV reactors are often placed in series and the ...

  • Fabrication of sponge biomass adsorbent through UV-induced surface-initiated polymerization for the adsorption of Ce(III) from wastewater

    The recovery of rare earth ions from industrial wastewater has aroused wide concern in recent years. In present work, we synthesized a novel three-dimensional adsorbent (denoted as LF-AA) by grafting loofah fiber with acrylic acid via ultraviolet radiation. The LF-AA was washed by boiling water and subjected to soxhlet extraction with acetone and then fully characterized by attenuated total ...

  • Forecasting of UV-Vis absorbance time series using artificial neural networks combined with principal component analysis

    This work proposes a methodology for the forecasting of online water quality data provided by UV-Vis spectrometry. Therefore, a combination of principal component analysis (PCA) to reduce the dimensionality of a data set and artificial neural networks (ANNs) for forecasting purposes was used. The results obtained were compared with those obtained by using discrete Fourier transform (DFT). The ...

  • 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 ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
