Ensuring Sustainability via Application of Root Zone Technology in a Rubber Product Industry: A Circular Economy Approach
Round 1
Reviewer 1 Report
General comments:
English language has to be carefully revised.
The title has to be rewritten.
Introduction:
L69: the sentence has to be revised.
The introduction should be much more specific. A wide description of pH measurement procedure, how a settler works, or the description of each pollutant is not required.
L25: Authors stated “Usually, protein is the main organic substrate in organic waste/wastewater. For example, the protein content in the organic fraction of sewage sludge ranges from 30%-70%.” This is wrong. What about vegetable and fruits wastes? Moreover, the value of 30% included in your example evidences that the sentence is wrong, since 30% is not a high content of proteins.
L 142: If experiments have been included, authors cannot state “This paper reviews the Root Zone Treatment System” because it is not a review. The main goal and the novelty have to be included.
Materials and Methods:
L145: Which kind of wastewater? Type of industry? This information is necessary. It is quite difficult to understand the text.
L150: The information reported is similar to the previous paragraph.
Please, authors should reconsider the number of figures included.
It should be included how authors measured the parameters (Standard Methods?), the statistical analysis, how the system performance has been evaluated, etc.
Results:
L 218: How do you calculate the efficiency?
All tables and figures have to show the standard deviation.
Why did you choose 15 days as the experimental time period? Could you add the flow rate or treated volume?
L226-241: Authors are only presented data but any discussion was included.
Figure 9: Is this a percentage of removal?
There is any comparison with the literature? Any conclusion about the experimental time or selecting the best technology? Advantages disadvantages?

Reviewer 2 Report
"Did unprecedented water pollution levels cause detachment in an industrial area by using root zone technology to promote circular economy "
Recommendation - The search is fragile in the discussion section. Accepted subject to significant revision but needs to be rewritten in light of the suggestions mentioned below.
1. Add some results in the abstract and conclusion (the Abstract should give brief information about the aims, findings, methods, and results of the research conducted in the article at a glance).
2. With the formulation of the introduction from lines 36-52 with clarification of the objectives of the study in the introduction
3. Reduce the repeated sentences in the meaning of the introduction.
4. Explain the characteristics of sewage wastewater before treatment
5. The search is very weak in the discussion section. The discussion section should give an interpretation of the significance of the results obtained with reference to similar works done by other authors. In addition, this section should describe the outcomes of the study.
6. The time give acceptable results in the first 10 minutes? Explain that.
7. Why don't explain other factors that affect on treatment process?
9. Set address numbers in their format.
10. Explain why the percentage of removal increased with increasing time. Explain with a break from previous studies.
11. Could you please improve the quality of all the figures and tables in the manuscript?
