Reviewer 1 Report
Comments and Suggestions for AuthorsThe manuscript presents an interesting topic for scientific community, however needs some improvements.
I suggest not including abbreviations in the abstract.
Please, correct formula of Li3PO4 (wrong in many places during all manuscript)
Please correct the typos (some of them highlighted in the text)
Do authors believe that the economic analysis is accurate? Which changes authors forecast with technology scale-up? Please include it in the manuscript.
I miss the application for pellets produced. Please include it in the manuscript.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe Li recovery from waste water is valuable for this article.
However, there are some corrected and additional points as follows,
In the introduction, please also mention the Li recovery from brine using the references for example,
Materials 2023, 16, 4190. https://doi.org/10.3390/ma16114190
Line118
Please write the meanings of SLin in the sentence.
In Figure 2, please write the y axis explanation in all graphs (a) to (e).
In 3.1.2
Please explain the reason of highest recovery of Li at pH11.5 more minutely.
Line 165, please explain the difference between Li3PO4 and Li3O4P.
Line 236,238
Please explain ν4 andν3.
In Figure3 (a) and (b), please indicate the scale more clearly.
Please show the maximum capacity to recover Li+ in fluidized bed.
Also please explain how to elute the recovered Li+ and recycle method of fluidized bed.
In conclusion, please write by point to point using values.
In supplementary information
Size distribution, Please use 2 digits after the decimal point.
In Figure S1, please show the error bars.

Reviewer 3 Report
Comments and Suggestions for AuthorsAbstract
The abstract was not well written. The introduction and the materials and methods part were not present in abstract. The abstract provides only the optimum conditions for the recovery of Li.
1. Introduction
The introduction part was well written, but the background about the Li recycling was lacking and also the background about the disadvantage of other processes was not provided enough.
2. Materials and Methods
The materials and methods part was well written, but the tools for analyzing wastewater need to be specified in the paragraph.
3. Results and Discussion
This part was well written, but Figure 2 and its caption needs to be revised. The axis title of each graph in figure 2 needs to be added and the figure caption was hard to understand even if it was with the figure. Other than that, Table 2 needs to be revised due to it is hard to read and the reference needs to be added the two references for the economic analysis were not enough.
4. Conclusion
The conclusion part was not well written. The details from economic analysis from results and discussion part was not refer.
