Rejection of Emerging Organic Contaminants by Nanofiltration and Reverse Osmosis Membranes

The demand for drinking water can lead many cities to implement indirect water reuse programs, where wastewater effluent becomes part of the drinking water sources. This title demonstrates nanofiltration (NF) and reverse osmosis (RO) to be appropriate technologies for removing a large number of micropollutants from the water.

Pollution of water sources with emerging contaminants (micropollutants) is a fact known worldwide. Although the risks of micropollutants in sources of water are partly recognized, interpretation of consequences are controversial; thus, the future effects of altered water with micropollutants remains uncertain and may constitute a point of concern for human beings when potable water consumption is involved. Therefore, many drinking water utilities target as an important goal high-quality drinking water production to lessen quality considerations that may arise from the consumers. In this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.
