  4. 3. Volatile fatty acid production from co-fermentation of primary sludge and food waste without pH control

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Binyam Bedaso; [2019]
    Keywords : Volatile fatty acid; Co-fermentation; Primary sludge; Food waste;

    Abstract : The production of volatile fatty acids (VFAs) from waste stream is gaining high attention because of their high market value and wide range of applications. In this study, the production of VFA from co-fermentation of primary sludge from wastewater treatment plant and food waste without pH control was evaluated using a pilot-scale reactor in a semi-continuous mode of operation.
