LIIKANEN R. / MATILAINEN A. / NYSTROM M. / et al. - ARTICLE DE PERIODIQUE - 2004

This study evaluates the removal of residual natural organic matter (NOM) from drinking water by nanofiltration (NF). NF removed NOM effectively from pre-treated surface waters. The residual High Molar Mass organic matter disappeared almost completely and Intermediary Molar Mass organic matter diminished considerably. Also the Low Molar Mass organic matter removal was improved. Of the tested membranes Desal-5 DL gave the best results in organic removal.
