Potable water production from pesticide contaminated surface water—A membrane based approach

The Influence of Water Matrix on the Separation of Selected Estrogens and Xenoestrogens by Nanofiltration

“…Większość obecnych oczyszczalni ścieków stosuje konwencjonalne układy oczyszczania oparte o procesy mechaniczno-biologiczne [Sarkar et al 2007]. Jednakże z powodu działalności czło-wieka takiej jak m.in.…”

Current status of pesticides application and their residue in the water environment in Ireland

“…Removal/treatment technologies are also necessary to secure the water environment from pesticide application. Studies have shown that conventional drinking water treatment processes are not effective in removing certain types of pesticides [25,26]. The chlorination process in disinfection of drinking water guarantees the removal of many of the pesticides that might be present in raw waters.…”

“…Despite this, the recent use of a wide variety of pesticides in agriculture means that it is difficult to adopt a simple method for the removal of pesticides since the process of separation depends on the chemical nature of the pesticide itself. Some of the methods currently being employed throughout Europe include preoxidation by chlorine, preoxidation by ozone, coagulation with aluminium sulphate, activation carbon filtration, nanofiltration and combinations of these techniques [4,5,7,[25][26][27][28][29]. Thuy et al, [29] investigated the extent to which pesticides are removed from water by coagulation-flocculation.…”

“…The study showed that the removal rate is always below 50%. Testing whether nanofiltration can remove pesticides from drinking water shows that this process has a good capacity to remove some pesticides from water and the membrane material used in the filtration process greatly influences the percentage of pesticides removed [25,27]. Ormad et al conducted a comprehensive study aimed to explore the effectiveness of the treatments commonly used in drinking water plants in Spain to degrade 44 pesticides systematically detected in the Ebro River Basin [6].…”

Membrane Treatment of Potable Water for Pesticides Removal

“…Because of this advances in membrane technology, RO has been gradually finding applications in the treatment of a variety of domestic, industrial, and hospital wastewaters. In the past three decades, the need for a complete assessment of the RO, and of the later developed NF process, regarding removal of pesticide residues from various aquatic matrices, led to an extensive research effort in many laboratories (Berg et al, 1997;Devitt et al, 1998a;Van der Bruggen et al, 1998Kiso et al, 2000Kiso et al, , 2002Košutić et al, 2002Košutić et al, , 2005Zhang et al, 2004;Causserand et al, 2005;Bhattacharya et al, 2006;Plakas et al, 2006;Sarkar et al, 2007;Plakas & Karabelas, 2008Ahmad et al, 2008aAhmad et al, , 2008bComerton et al, 2008;Caus et al, 2009;Benítez et al, 2009;Pang et al, 2010;Wang et al, 2010), pilot (Baier et al, 1987;Duranceau et al, 1992;Agbekodo et al, 1996;Berg et al, 1997;Hofman et al, 1997;Wittmann et al, 1998;Bonné et al, 2000;Boussahel et al, 2000Boussahel et al, , 2002Chen et al, 2004) as well as to industrial scale experiments (Agbekodo et al, 1996;Wittmann et al, 1998;Ventresque et al, 2000;Cyna et al, 2002). A fairly large number of commercially available NF/RO membranes have been tested for the removal of an even larger number of herbicides, insecticides, fungicides and miscellaneous pesticides from various water matrices.…”
