  • Evaluation of novel hollow fibre membranes for NOM removal by advanced membrane autopsy

    A full-scale inside out hollow fibre membrane module was operated in a pilot-scale water treatment plant in Sweden for a period of 12 months from August 2013 to July 2014. Liquid chromatography– organic carbon detection (LC-OCD) chromatogram indicated the membranes could effectively remove 86% of dissolved organic carbon and 92% of humic substances from the feedwater. Routine cleaning-in-place ...

  • Key issues of ultrafiltration membrane water treatment plant scale-up from laboratory and pilot plant results

    Industrial-scale ultrafiltration (UF) membrane systems have gained wide acceptance for producing safe drinking water. Laboratory and pilot plant studies are often carried out prior to the design of full-scale water treatment plants. Emphases are laid on how accurately these laboratory and pilot plant studies represent actual industrial-scale systems and the limitations. A case study which ...

  • Membrane Technology in Water Treatment in the Mediterranean Region

    Water is the most essential resource of life. About 97,5 % of the World’s water resources (1.386 Mio km³) are salty seawater, not usable for agriculture, technical purposes or simply quenching the thirst of about 6 Billion people on Earth. Just 2.5 % of the world’s water is fresh water, but only 30 % of it are accessible for us, either as groundwater or as surface water bodies. ...
