Abstract: The present invention relates to a system and a method for abating the presence of a selected chemical substance in wastewater flowing in a wastewater channel system from an upstream position to a downstream position. The method typically comprising dosing into the wastewater, at the upstream position, chemical agent(s) adapted to abate the presence of said selected chemical substance, wherein the dosing is in an amount set by a dosing set-point, and adjusting the dosing set-point based on determinations of the concentration of the selected chemical substance at the downstream position. The invention involves comparison between a determined concentration and a pre-selected fractile and adjusting a dosing set-point based thereon.
