  • Water quality testing: solutions from catchment to waste

    Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused.1Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle ...

  • LG Sonic to automatically predict algal blooms

    LG Sonic will make use of Artificial Intelligence (AI) to further develop the software algorithm which will make it possible to predict algal blooms based on water quality data automatically. Furthermore, it will provide detailed information about the intensity and the impact of the algal bloom on the ecosystem of the water body. The updated algorithm will be implemented in LG Sonic’s ...

  • The effect of sodium thiosulfate dechlorination on fecal indicator bacteria enumeration: laboratory and field data

    In microbiological water quality testing, sample dechlorination with sodium thiosulfate is recommended to ensure that results accurately reflect the water quality at sample collection. Nevertheless, monitoring institutions in low-resource settings do not always dechlorinate samples, and there is limited research describing how this practice impacts drinking water quality results. The effect of ...
