Effects of temperature, storage time and pH on survival of Escherichia coli in source-separated yellowwater

Laboratory‐scale experiments on the survival of Escherichia coli in raw, undiluted, freshly collected, source‐separated yellowwater were performed. Concentrations of E. coli and its survival at different temperature regimes and storage times were measured in yellowwater originally cross‐contaminated with faeces and yellowwater purposely contaminated (deliberately spiked) with faecal material. The temperature regimes of cold (4°C), mild (10°C) and warm (22°C) were the limited factors, whereas the storage time of the contaminated yellowwater was unlimited and lasted until the E. coli concentrations reached the limit of detection of
