  • Characteristics of natural organic matter and formation of chlorination by-products at Masaka waterworks

    To minimise the formation of chlorination by-products (CBPs) it is imperative that attention is directed towards the structure and occurrence of natural organic matter (NOM) in raw water sources, and its flow and fate during water treatment processes. In this study, an assessment of the characteristics and flow of NOM along the treatment train at the full scale treatment plant at Masaka, Uganda, ...

    First SELCOPERM unit installed within the Czech Republic to serve for potable water disinfection through the electrical chlorination method ŽLUTICE, Czech Republic: 1/3 of the total capacity of the waterworks at Žlutice has been designed for supplying drinking water to a group of communities found within the catchment area of Žlutice (approximate population of 14,000), the remaining 2/3 ...


  • Removal of natural organic matter and trihalomethane formation potential in a full-scale drinking water treatment plant

    A multidisciplinary approach was applied in this work to characterise natural organic matter and evaluate the performance of a full-scale waterworks treating organic-rich surface water. It was shown that the combination of the treatment processes considered efficiently removed the dissolved organic matter, including its specific fractions. Most of the dissolved organic carbon and nitrogen (DOC ...

  • Characterization and comparison of iron oxyhydroxide precipitates from biotic and abiotic groundwater treatments

    Removal of iron is an important step in groundwater treatment for drinking water production. It is performed to prevent organoleptic issues and clogging in water supply systems. Iron can be eliminated with a purely physico-chemical (abiotic) method or biotically with the help of iron-oxidizing bacteria (FeOB). Each of the purification methods requires different operating conditions and results ...

  • Water–energy–carbon nexus: a case study of Bangkok

    An understanding of the nexus between water and energy and greenhouse gas (GHG) emissions is essential for sustainable water resources management. While a number of such studies on understanding this nexus have been carried out in the recent past, there have been virtually no studies that have done so for Asian cities. This study aims to plug this gap by analyzing the water–energy–carbon (WEC) ...
