Abstract: The removal of the non‐ionic surfactant Triton X‐100, dosed at 30 and 300 mg/L in a pilot‐scale subsurface horizontal flow reed bed, and the aerobic heterotrophic cultivable community associated with the roots and with the substrate gravel in both absence and presence of Triton X‐100 were investigated. t‐Octylphenol (OP) and its mono‐, di‐ and tri‐ethoxyl derivatives, among others, were found in the outlet. A mass balance allowed us to calculate that approximately 40% of the Triton X‐100 metabolites OP and octylphenol polyetho...
