Pretreatment of Rubber Additives Processing Wastewater by Aluminum–Carbon Micro-Electrolysis Process: Process Optimization and Mechanism Analysis

Round 1

Reviewer 1 Report

This study has some novelties, such as the use of real wastewater and a few previous studies on rubber processing wastewater. There are some major issues and many minor errors. My detailed comments are below: 

Please check the subscription and superscription (Ex. Line 268). All variables should be presented in italic. Check all typos (Ex. Line 268, o.8656). "p-value" should be "p" not "P"

Please provide the previous studies on the treatment of rubber wastewater in the introudction part.
The standard units (mm or micro meter) for 1~3 meshes should be provided.  
Please check the English grammar. Ex.) Typically, the sentence can not start with a numerical number. (Line 106-107.)
Line 110: Please provide the material, production company, and country of syringe filter.
Please provide a more detailed procedure for analyzing chroma. (Line 114)
Line 128: Provide the production company and country of the software.
Table 2 is not necessary.
The caption of Figure 6 should describe the subfigures such as (a), (b), ~~~.
Line 264-266: The p-value of X1 is > 0.05, indicating that X1 is not a significant term. This statistical result is not consistent with the description in Line 174-176. "These above results suggested that removal efficiency of organic compounds was strongly pH dependent."
The authors should describe the effect of the interaction of two terms in Chapter 3.3.

Reviewer 2 Report

Dear Authors,

The manuscript submitted to Water focuses on evaluating certain industrial wastewaters treatment processes using Al/AC micro-electrolysis, which has promising results in this field. Also, it is shown the short mechanism analysis of the Al/AC micro-electrolysis process for the decomposition of organic matter and optimizing the experimental conditions by statistical analysis and modelling.

The work is generally well written but requires some minor corrections for better clarity of information.

From a scientific point of view, the manuscript generally presents accurate and correct data among the complete statistic analysis. The used analysis methods are correctly selected and applied to the protocols presented in scientific literature.

The studied subject is complex and approaches subtlety interdisciplinary areas, making the presented data valuable. The manuscript Title is appropriate with the study, and the Abstract covers the general content of the original article.

The Introduction section includes current information considering general about the process chemical reactions and some assessments about applied micro-electrolysis, justifying the objectives of this study. The experimental section includes relevant details of the analysis methods and data analysis.

Regarding the Results and Discussions sections, all data are generally clear, accurate, and correct presented in all tables and figures, including the necessary data for a good understanding and completed with all good remarks correlated with others data described in the literature.

The conclusions are correctly summarized and supported by the reported data on the studied subject's contribution.

 

In the manuscript, there are some minor typing errors:

L 135 (Please, see the eq. 7 and put correctly the variables i and j on symbol sum); L144 (adj. R2); L158 (...to pH value. because the change...); L257 (Please, assign other no. for eq.); L268; Table 2 (initial pH) and so on. 

Considering the above, I recommend that the manuscript publication be accepted after minor revision.
