Maximizing Bio-Hydrogen and Energy Yields Obtained in a Self-Fermented Anaerobic Bioreactor by Screening of Different Sewage Sludge Pretreatment Methods
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe previously pointed out requests were not sufficiently reflected and modified (the following contents). It is difficult to publish until it is corrected.
1. The paper needs to include additional details on the measurement methods for characteristics such as volatile solids (VS) and total solids (TS) mentioned in the paper.
2. Data duplication is observed in both Table 1 and Table 2, requiring the removal of redundant information.
3. Is there no result for the chemical composition analysis of the initial sewage sludge used as an experimental material? Such information would be crucial for interpreting changes in hydrogen yield due to pre-treatment.
