Hi
I have done the removal of heavy metals from the aqueous solutions through batch experiments. I observed that with increasing the concentration adsorbent (g) the % removal of heavy metal has increased almost 100% but the adsorption capacity (mg/g) has decreased. Are these two entities are inversely related to each other? While optimizing the experiments which factor should be considered more important % removal or adsorption capacity w.r.t. manuscript as well?
Thanks for your response in advance.

Hello my dear friends,
I am looking for a disinfection method with 4-6 log10 pathogen reduction, which does not require much energy, chemicals and finances. I am going to use it for decentralized wastewater treatment in developing countries. My main treatment stage would be constructed wetland (maybe hybrid CWs). I konw that Chlorine, Ozone, UV, microfiltration or reverse osmosis have high efficiencies. But becuase they are cost intensive and need expert operators, I cannot consider them as the a realizable method for my design. I would apprecite it, if someone could help me.
How can constructed wetlands be used as wastewater treatment
Twenty years ago I operated a biofilter for wastewater treatment. I set layers like this (Pic_004_b):
Superficial layer: earth with live earthworm (Eisenia foetida).
Layer 1: sawdust
Layer 2: gravel diam 3/8"
Layer 3: gravel diam 1/2"
The remove BOD5 (biochemical oxygen demand in five days) efficiency was 79.6 %, but chemical oxygen demand (COD) for both influent and effluent was the same.

I have done an adsorption test for B-removal of an initial concentration of (10ppm).
After adsorption, the results of B were higher that 10, (not much- the maximum was of 13ppm) but i still can't proceed with the calculations as the data are higher than 10.
I've attached the result file.
I hope any can clarify what is the best way to adjust the data/or how to deal with them..!!

I am working with wastewater treatment......
It seems to be transmitted by rodents. As we know, sewer mains are habitat for rats which frequent cities. Thus, there is a question of transmission prior to the raw sewage reaching the wastewater treatment plant. Thus, there is a question of the pox virus surviving the treatment process. It has been proposed that SARS-CoV-2 can be picked up by fecal bacteria as lysogens, is the Monkeypox able to also do this? If rats (rodents) can carry this, is there any chance of also carrying both Monkeypox and SARS-CoV-2 and a reassortment?

Hi everyone, I'm working on application of Extracellular Polymeric Substance as coagulant / flocculant in wastewater treatment. After inoculated with EPS, floating scum formed which suspended solid did not sediment well. How can I sediment the scum effectively? should I combine my EPS with other chemical coagulant like FeSO4 or alum? or is there any method to add posiitive charge on EPS so that it can settle well? Thanks.
Hello everyone!
I am currently seeking any PhD opportunities in the field of wastewater treatment. However, before reaching this step, I want to publish few papers (either journals or conferences) in this field.

What is the best (low cost and high efficient) method (Physical, Chemical, or Biological) of wastewater treatment to meet irrigation water quality ranges?
Hi all,
I'm using a tubular magneli phase Ti4O7 as the anode and a mesh of SS that cover the anode as the cathode to remove some pollutants from the synthetic wastewater.
Based on my knowledge, the reactor should not be producing sludge with clean water. However, some sludge has been produced during the reaction, and it seems that is for corrosion. I double-checked that the electrodes and clips were completely submerged in the water, the applied current was less than that the manufacturer has suggested as the best current that the electrode can stand, the alligator clips were connected properly to the anode and cathode, and I even ran it with pure water and still, some sludge was produced as you can see in the attached photos.
Do you have any thoughts on how can I fix it and what would be the reason?
What is the approximate COD value of 50 ppm aqueous Acetaminophen solution (C8H9NO2, Mol wt 151.163 g/mol)?
I am trying to use SWMM for wastewater treatment (BOD removal) by applying storage tanks in series. The volume of tanks was different. I used three scenarios (the first tank is bigger than the second, the first tank is smaller than the second and both tanks have the same volume) the first tank always performed better even when it is small or equal to the second tank. If there is someone who can help me to explain this behaviour? kindly help.
I what to determine BOD rate constant at temp. 30 degree C. For that I have to rate a constant for 30 degree C. I know the value of Theta 1.047 or 1.056 but what does Theta refer to? For e.g. K20 is BOD rate constant at 20 degree C similarly what is Theta in the same equation?

What factors lead to Orthophosphate increase in microalgae-based wastewater treatment?
Hello Everyone,
I am trying to reduce MLSS of Aeration tank (vol= 27,500 KL) from 9000 ppm to 6000 ppm. For which we are wasting 250-300 KL/Day with concentration of 30,000 ppm MLSS (apprx. 7500-9000 kg of MLSS/Day) from almost 3 weeks, but still it reduced to only 8000 ppm.
we are also adding 4,800 KL of sewage (with SS conc. of 180 ppm) per day in aeration tank to maintain microbe population.
Following are the specifications.
1) influent SS= 200 ppm (with influent flow of 19,000 KL/Day)
2) RAS= 7500 KL/Day
3) WAS= 250-300 KL/Day
4) outlet SS= 230 ppm
5) Aeration tank MLVSS= 5000 ppm
Please help me to understand how this is working?
What is the main mechanism of wastewater treatment through microalgae in open ponds and closed cultivation? How does it work when there is no oxygen and carbon dioxide in closed cultivation?
Types of wastewater: Biodiesel wastewater
EQ TSS: 900mg/L
EQ TDS: 1800 mg/L
After chemical dosing TSS: 7000mg/L
No overdose coagulant. Less/no metal precipitation process involved in the chemical treatment process.
Generally, after the coagulation and flocculation process, the TSS will be slightly higher than that at EQ. Is there any content that is unable to detect by TSS and TDS testing method but will occur as SS after chemical treatment?
Could anybody suggest the stable organic-framework materials with Pd metal (as a central metal or in combination with different transition metals) and inner-sphere organic ligands (e.g., pyrazine, thiocyanate, acetate, azide and oxalate) for application of water and wastewater treatment?
To reduce the dimensionality of large datasets and find the correlation between the parameters. If the Inlet and outlet parameters are present should we include the inlet as well as outlet parameters or include them separately?
I am venturing on microplastics or other contaminants that can be eliminated in water, wastewater or even sediments using electron beam technology.
