  • Comparison of optional process configurations and operating conditions for ceramic membrane MF coupled with coagulation/flocculation pre-treatment for the removal of NOM in drinking water production

    The increase of Natural Organic Matter (NOM) in natural water sources, partly caused by progressing climate change issues, is a growing concern for drinking water production. In recent years, membrane technology like Reverse Osmosis (RO) or Nanofiltration (NF) has been successfully applied as a robust solution for NOM removal to produce potable water. However, coagulation/flocculation ...

  • Nano this and Nano that?

    Several terms, each with the prefix “nano-”, are now in use in the fields of filtration and its related separation processes, and it is important to be able to differentiate among their nuances of meaning. Firstly, there is nanometer itself, from which the others derive, and which is precise, measuring one thousandth of a micrometer or one millionth of a millimeter. It is thus a very ...

  • Ideal treatment of laundry wastewater with ultrafiltration installations

    Treatment of very dirty work clothing also produces heavily polluted, oily/greasy wastewater. It is the aim of laundry wastewater treatment to reduce fresh water consumption and to minimise the volume of residuals. At the same time, adherence to the limit values according to appendix 55 of the General provisions on hydrocarbon, heavy metal and AOX contamination in wastewater must be guaranteed. ...

  • Picking Their Membranes - Part I -

    Membrane use by water suppliers may not be new, but suppliers are considering membranes in new ways -- by number and variety of applications. Membranes can work on a wider range of resource waters, more efficiently and for less cost than before. Among membranes' attractions as substitutes for conventional water-treatment technologies, such as filtration, distillation and ion-exchange are: ...


  • Ozone Brings Better Bottled Water
