Round 1

Reviewer 1 Report

Please, error bars should be added to all results. 

The adsorption process takes a very long time compared to literature. What is the novelty of the work?  

Please, update the conclusion section. 

Add the type of the microorganisms detected in the wastewater.

Reviewer 2 Report

Line 44: I fail to understand the use of “nice” in this situation.

Line 64: membrane fouling is also a problem of MFC

Line 109 and 110: why use pH 7 and 25 °C ?

I believe that chapter 3.1 Cyclic Voltammetry lacks comparison with other studies to understand if similar conclusions have been drawn when using CNTs coatings for other types of wastewater.

Lines 241 and 242 Kloch and Toczyłowska-Mamińska do not appear in references. Additionally, have these authors achieved this conclusion under what conditions? Same dye and anodes? Please clarify.

Figure 4 refers to which cycle? Have the authors tested different external resistances? Could this aspect influence COD and dye removal? Please clarify.

In “3.3 Comparison of phases“ a comparison with other authors’ MFC energetic outputs with other types of plates, using dye wastewater, could improve the overall quality of the paper.

Line 288: what is the previous experiment referred to in [49]?

Did the different initial dye concentrations (30, 55, and 80 mg/l) have an influence on power generation?

Line 311 and 319: the study’s descriptions should include the anode and cathodes and concentrations used for better comparison.

Conclusions: What do the authors consider as “sufficient power density”? This is very ambiguous, please provide a quantification of this value or, as mentioned above, provide a bibliography for comparison in the results and discussion section.
