Glyphosate Removal in Drinking Water Treatment

September 29, 2013 Categories: Latest News

Glyphosate is one of the most widely used herbicides in the world and its use has steadily increased in recent years. Glyphosate is used on a commercial scale and also as a household product e.g. glyphosate is the active ingredient in e.g. Roundup. To gain a better understanding of how glyphosate can be removed from water, WRc carried out a review for the Glyphosate Environmental Stewardship Steering Group on the removal and degradation of glyphosate in water treatment. 

Knowledge gaps were identified and additional tests carried out to fill these gaps. The work has now been accepted for publication in the Journal of Water Supply: Research and Technology – “AQUA”. 

Results from the work indicate that chlorination, ozonation, advanced oxidation processes, nanofiltration and reverse osmosis can generally provide a good removal of glyphosate. Biodegradation and adsorption processes can also be highly effective in removing glyphosate in bank filtration and slow sand filters. The removal by coagulation, UV, activated carbon, ultrafiltration and air stripping is on the other hand poor. 

This project supports the work of those companies involved in the Glyphosate Steering Group as they strive towards the sustainable use of glyphosate.
