Removal of N and P in a Rotating Biological Contactor Plant: Case Study Agnita, Romania

Round 1

Reviewer 1 Report

The manuscript focused on the removal of N and P in a rotating biological contactor plant. 

I would like to point out that the presented topic is very interesting and the manuscript is well organized. English is fine.

However, the manuscript should be improved before the publication. For this purpose, please, see the comments below:

1. The introduction does not include all relevant references. For instance, the Authors wrote (lines 70-73):

Among the best technologies used for nitrogen removal are: moving bed biofilm reactor (MBBR), moving bed biofilm reactor-membrane bioreactor (MBBR-MBR), moving bed membrane bioreactor (MB-MBR) and integrated fixed-film activated sludge (IFAS) process [28–31].

This information is not sufficient. In order to better present this subject, please see the following recently published review paper:

DOI: 10.3390/en15144981

2. The novelty of the worh should be pointed out.

3. The quality od Figures should be improved. For instance, Figure 6 is completely unreadable.

4. The obtained results should be compared with those available in the literature.

Reviewer 2 Report

Dear authors,

 

The work is well written with a lot of results, the topic is interesting, that is, you turned the project into a work.

I assume that you analyzed the water using various instrumental methods, and based on the analysis, applied your purification method?

 

Have you used anything other than FeCl3 to use?

Also, did you deposit chloride in the distributor, and if it did, how did you solve the problem?

As for me, I am in favor of accepting your work with minimal English correction.
