Predicting turbidity and Aluminum in drinking water treatment plants using Hybrid Network (GA- ANN) and GEP
Abstract. Turbidity is the most important parameter needed to check the status of drinking water, as it is an integrated parameter because its high values indicate high values of other parameters related to water quality. Coagulation and flocculation are the most essential processes for the removal of turbidity in drinking water treatment plants. Using alum coagulants increases the aluminum residuals in treated water, which have been linked to Alzheimer's disease pathogenesis.
In this paper, a hybrid algorithm (GA-ANN) used to predict the turbidity values in the drinking water purification plant in Al Qusayr was used.
The models were constructed using raw water data: turbidity of raw water, pH, conductivity, temperature, and coagulant dose, to predict the turbidity values coming out of the plant.
Several models built and fitness detected for each model, the network with the highest fitness was selected, and then a hybrid prediction network was constructed.
The selected network was the most able to predict turbidity of the outlet with high accuracy with a correlation coefficient (0. 9940) and a root mean square error of 0.1078.
And 4 equations for determining the value of the residual aluminum was obtained using Gene expression method, and the best equation produced results with very good accuracy, in this regard it can be referred to RMSE = 0.02 R = 0.9 for the best model.

The article in general is good written and it is about a very important issue related to drinking water treatmentI noticed that the refrences are quite new. And tge equation gives the article more stringth, likewise the GUI .
But I have a question why the researcher used Ga and Ann and GEP
not fuzzy for example?
And at the end of the article I think it is good to mention the other 3 equation that reselted from the research, not just the best one
GOOD LUCK

We used GA-ANN Because there is some articles on the internet about predicting turbidity and other parameters by Fuzzy logic
So to do something new , we used ANN Hybrid with GA, GA was used because many researches in other fields said that GA can improve the structure of ANN. And it gave great results comparing to similar researches.
And for the other 3 equation, I can provide them in the final copy if I am allowed to add something to the article.
GEP was great tool for predicting in a very amazing way.

In the present work the authors propose and application of data driven approaches for predicting water turbidity and residual aluminum in drinking water treatment plant. The paper is within the scope of the journal, few similar studies can be found in the literature especially regarding the prediction of residual aluminum which is very interesting. However, the paper with the actual form is with low quality and needs to be in depth amended and reorganized before to be ready for publication.
- English is below the required level, and the paper is hard to read and to understand what is really done by the authors. Native English speaker can help in improving the English style of the paper.
- From the abstract to the conclusion, the paper needs to be completely reorganized, structured and presented in a clear manner. The actual form is unacceptable, and the paper is without a clear ideas.
- Poor literature review and missing research gap.
- Theoretical description of the models is out of scope.
- Some information’s were provided by the authors and not related to the investigation, i.e., the GRNN model (line 145)???
- Results should be deeply analyzed and discussed.

In this paper, a Hybrid network (GA - ANN) which is a data-driven method, was proposed for predicting water turbidity, and GEP which is a promising tool in many fields, was used for the prediction of residual aluminum in drinking water treatment plants. There are a few similar studies in scientific journals, particularly for the prediction of residual aluminum, which was done in this study, and it is a very interesting topic and related to the journal reach.
- The English language should be checked by native English speaker .
- I think the abstract could be rearranged to give more information about the article.

The issue is also important for water purification plants due to the importance of turbidity in assessing the stability of the plant’s work and controlling aluminum values
But it needs some modification and revision, especially with regard to the language, and it is preferred to be reviewed by a native English speaker
And although that there are some new references, It is also preferable to add other reference studies in the foregroundCitation: https://doi.org/10.5194/dwes-2021-8-CC4 - AC5: 'Reply on CC4', Ruba Alsaeed, 14 Apr 2021

This paper is good in overall. The subject of this article is very important todays because of Lack of drinking water resources as well as Existence of pathogenic aluminum particle. In general, the following appear: 1. Almostly new and very interesting subject and new method for solving the problem (there are some article with Fuzzy). This is in scope of the journal. 2. The references are quite new.3. The English language should be checked. I think it will be better.4. The quality of some figs must be better. Ex: fig.85. The abstract must be written in 1 paragraph.

Thank you for mentioning that methods that were used (GEP and hybrid GA -ANN) were new in solving this kind of problems
as you said there are some articles that worked with Fuzzy systems and GMDH.You are right figure 8 needs to be more clear, I have fixed this

This paper was well prepared.
The stringth points are:
- There are few articles that studied predicting turbidity and much less for the aluminum prediction.
- Also, using GEP in the field of water treatment plants is very promising.
- Predicting models are very important, especially when they are combined with Early Warning Systems.
- Comparing the results of MLR with ANN was very reliable
cause this parameter have nonlinear relations and it is hard to be described using linear ways
However, this paper still needs some further improvements.
1.There is some grammatical and structural errors.
2.The authors did not discuss the limitations of the data set they used.
3.In figure 3 what is the program used to make this figure?
4.figure 7 needs to be more clear.
The article is suitable for publication after some language editing.Citation: https://doi.org/10.5194/dwes-2021-8-CC8 -

The paper is about the modelling of the removal of turbidity and the concentration of residual aluminium during coagulation at a surface water treatment plant. This is an important topic, since accurate dosing of chemicals can lead to better performance of the plant and cost reduction. However, the quality of the paper is low. The use of references in the introduction and for the discussion of the results is poor, and the manuscript has severe language issues. In addition, the manuscript has redundant and superfluous information, including figures and tables (e.g. Fig 1, 2, 4, 8, 10; Table 1, 6). Moreover, a discussion lacks on the quality and usability of the data. Data are used from an existing plant that is operated. The obtained data are thus not independent and the results are biased. How can the model then be used in future to optimize coagulant dose?
General comments:
- Let the language be checked by a native speaking person
- Explain at the end of the introduction, what the “knowledge” gap is, what the “objective” of the study is and how it “contributes” to science/engineering.
- Avoid too much theoretical background and explanation of the used models, but concentrate on the reason why they are used and how they can be used.
- Avoid giving results of the modelling efforts in the Materials and Methods section
- Conclusions section should only give short introduction with objectives and main findings (without references)
Specific comments:
- Line 3-4, avoid too general introductions
- Line 8, explain that turbidity also has to do with “organoleptics”
- Line 10, delete (not a clear sentence)
