“…The concept of the EWS presented in this paper is convergent with the attitude presented by G.Black et al [3]. Available analyses and research provide valuable information required for development and design of the device [1][2][3][4][5][7][8][9][10]. Despite understanding the essence of the problem, EWS for toxic upsets prevention is not commonly used in sewage network.…”

“…Toxicity of wastewater can be measured with many different methods [2,3,[5][6][7][8][9][10]. Not every method can be used in toxicity warning system as they do not comply with its requirements which are: short time of response, easy handling, reliability and on-line data registration.…”

Abstract. The article presents a concept of an EWS (early warning system) for toxic sewage detection upstream from Wroclaw Wastewater Treatment Plant. It includes design and construction of three toxicity warning stations, situated in municipal sewage system. Early detection of toxic contaminants provides time for corrective actions. Wastewater toxicity level is based on activated sludge OUR (Oxygen Uptake Rate) measurement. The database of normal level of activated sludge OUR is collected during the measurement initial phase. Hence, if toxic event occurs, device will measure decreased OUR value and WWTP operators will be alarmed. Additionally, flow measurement is carried out. It allows to estimate the volume of a toxic stream. Development of the early warning system requires solving minimum six different scientific and technical issues and is a subject for a complex research project.
