Monitor Cations in CPI Wastewater for Better Performance

By Bart Peeters and Sabine Herman, Monsanto Europe |

    A detailed follow up of the cations present in the wastewater of the Monsanto Europe site in Antwerp, Belgium, has led to an increased understanding of changing wastewater treatment plant performance. The chemical process industries’ (CPI) other wastewater treatment plants that handle continuously changing mixtures of different manufacturing plant effluents should also consider routine monitoring of cations in evaluating treatment plant performance. These data can help explain changes in sludge settleability, changes in solids losses from the final clarifiers and changes in dewaterability of the waste sludge — important but at the same time difficult questions to answer. This article shows how the operational team at Monsanto Antwerp used daily cation monitoring, as part of a Six Sigma project, to explain "unexplainable" phenomena observed regarding the biology of the plant’s activated-sludge system during a 1.5-yr period.   Wastewater treatment A primary purpose of industrial wastewater treatment is to remove suspended and soluble organic constituents from wastewater. The activated sludge process is the most commonly used biological process to degrade these organics in wastewater. In…
