“…Snyder et al (2007) confirmed that the vast majority of PPCPs spiked to a secondary effluent were not rejected when passing through an UF system, although estrogens (E2, E1 and EE2) were well removed (91-99%) which was attributed to their relatively high sorption properties, even though other compounds as for example HHCB did not follow this pattern. Although the technical feasibility of membranes has been demonstrated, their implementation is still limited because of the high investment and operational costs involved (Alonso et al 2001). If membrane filtration is required as a post-treatment technique for an efficient removal of micropollutants, nanofiltration (NF) and reverse osmosis (RO) constitute an interesting alternative (Snyder et al 2007).…”

The presence of bioactive trace pollutants such as pharmaceuticals and ingredients of personal care products (PPCPs) in different environmental compartments (rivers, lakes, groundwaters, sediments, etc.) is an emerging issue due to the lack of existing information about the potential impact associated with their occurrence, fate and ecotoxicological effects. Due to the low PPCP concentrations reported in wastewaters (ppb or ppt) and their complex chemical structure, common technologies used in sewage and drinking water treatment plants may not be efficient enough to accomplish their complete removal. Information about physico-chemical characteristics such as acidity, lipophilicity, volatility and sorption potential is a useful tool to understand the different removal patterns observed. In order to perform an accurate overall mass balance along the different units of sewage treatment plants, it is necessary to gather information not only about the presence of micropollutants in the aqueous phase, but also on the fraction sorbed onto solids. Since only some PPCPs are very well eliminated by conventional sewage treatment configurations, new strategies such as modification of operating conditions (e.g. solids retention time), implementation of new technologies (e.g. biomembrane reactors) or additional advanced post-treatment steps (e.g. oxidation, adsorption, membranes) have been suggested for an increased efficiency.

“…Field data is preferable, however, literature data is also used when field data is lacking. For the complex data requirement option 1 of CMF, field data was obtained from the Rouse Hill water recycling plant with the use of literature data to supplement the data set where necessary (Schafer, 1999;Alonso et al, 2001;Bersillon and Thompson, 1996;STOWA, 2001). For the simpler data requirement options 2 of MBR and WSP, reliable literature data was used (Aquatec Maxcon Pty Ltd., 2003;Vigneswaran et al, 2001;Schafer, 1999;Bersillon and Thompson, 1996;Holler and Trosch, 2001;Manem and Sanderson, 1996;Reed et al, 1995;Metcalf and Eddy, 1991;Toumi et al, 2000;Nameche et al, 2000;Garcia et al, 2000).…”

Environmental performance of different water recycling technologies is compared on the basis of the associated potential environmental impacts using the technique of Life Cycle Assessment (LCA). The LCA method is used here to support decision making in water recycling in terms of (1) comparison and selection of suitable technology and (2) identification of opportunities to enhance the environmental performance of the water recycling train. In addition to the conventional impact categories used in LCA, a new soil salinisation potential is included. The environmental impact contribution from the construction phase of each technology is estimated using the Missing Inventory Estimation Tool (MIET) approach which relies on the input-output analysis technique. LCA results are reported and discussed in detail in this paper and areas of potential improvement are identified including: (1) sludge quality and quantity, and (2) energy consumption. The suitability of using the LCA technique in the context of water recycling is discussed and the limitations of LCA for this particular purpose are outlined and further research needs identified.

“…COD and BOD removal efficiencies, therefore, were approximately 57.5% and 66.7%, respectively. These removal efficiencies may result from the type of organic fraction that is mostly in suspended form (Alonso et al 2001). …”
