Integrated membrane systems have been recently proposed as suitable alternatives to overcome existinglimitations in traditional seawater reverse osmosis desalination plants. By this approach, submerged hollowfiber ultrafiltration have been chosen as pretreatment because of the lower energetic consumption and thegreat significance for reducing particles deposition on the membrane. This work focuses on the study of theinfluence of a set of operating conditions and the fouling dynamics when operating submerged ultrafiltrationunder subcritical flux conditions for relatively long-time.According with results, submerged hollow fiber ultrafiltration can be considered as a feasible pretreatment inreducing natural organic matter from seawater, provided that the opportune operating conditions were wellidentified and optimized.

Abstract
Integrated membrane systems have been recently proposed as suitable alternatives to overcome existinglimitations in traditional seawater reverse osmosis desalination plants. By this approach, submerged hollowfiber ultrafiltration have been chosen as pretreatment because of the lower energetic consumption and thegreat significance for reducing particles deposition on the membrane. This work focuses on the study of theinfluence of a set of operating conditions and the fouling dynamics when operating submerged ultrafiltrationunder subcritical flux conditions for relatively long-time.According with results, submerged hollow fiber ultrafiltration can be considered as a feasible pretreatment inreducing natural organic matter from seawater, provided that the opportune operating conditions were wellidentified and optimized.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
