In this ,experiment,, we used sample two-liter volumes of the activated ,sludge, collected from the local ,treatment, facilities in our laboratory scale bio-reactor (glass beakers). The sample was aerated for a time period of ten minutes and after interruption, the change in DO was measured. DO measurements were made using sensors and a real time data

16/5/2019, · The ,excess sludge, (ES) generated from wastewater ,treatment, plants entails high expenditure for its ,treatment, and disposal. In this study, firstly, the influence of mild-thermal (70 and 90 °C) and alkali-(pH 10 and 11) pretreatment methods on solubilization and acid generation from ES was investigated. The experimental results showed that the solubilization (SCOD/TCOD) increased as ...
