- The basics of nitrogen removal in wastewater treatment systems. Focusing on biological nitrification and denitrification. This applies to most all biological reactors, but the video focuses on the Carrousel System by Eimco Water Technologies.
Dear Steven,
This is a very focus video on netrogen removal process in Waste water treatment plants. Thank you for making this.
Steven,
This is without a doubt, the clearest and most informative description of the wastewater nitrogen removal process I've come across.
+Michael Kayak Thanks for the feedback! Glad you liked it.
I Agree! This is perfect for my aquaculture classes. Fabulous work!
@Caroline Trembath
I'm so happy to see you are studying aquaculture. I'm going for a bachelor degree in environmental science. Now I study micro biology.
My hobby is aquaponic and are very interested in aquaculture as well.
Sustainability is my motto (could you guess hahaha) and I would live to talk with someone in this topic (aquaculture).
I'm trying to find solutions for dinitrifacation as nitrate is the hardest impact in aquaculture. Sure you have seen pic's from Laguna de Bay in Philippines (just Google if you have not already seen it).
Enough for now;)
Beware, english is not my native tongue. I'm from Scandinavian country, so bear with me;).
If you are interested pls contact me (not sure if it's possible to from here). However, that's not a problem. Dot down some words here and I'll give you my mail. I don't care about spam, I'll soon change may adress soon anyway hahaha.
If not, I which you all the best with your studies!
Agreed this has enlightened my mind.
Yeh, not too bad at this game is he/they?
You don't know how helpful this video was to me... i am so grateful. Thank you so much!
Thank you so much for this awesome video, helps me a lot
thanks for this very impormative video i just want to ask if there any chemical subtance can reduce nitrate and phosphate
I know the way to go now. Thank you!
I can has cheeszburger? Lol, thanks for the video, extremely helpful for my class.
You are superior
keep going
An interesting video to me, but that the transcript described in form of the text is full of mistakes, f.e. the speaker says eutrophication while in transcript it is RUclips vacation, or denitrification is D nitrification, etc etc??
+Laura Daija Icing kits boards beach wreck ignition. :-)
Any chance of doing a video about Cod removal?
You got me. I'll have to harass my proof readers for not catching that...
This video makes so much sense after a whole semester of trying to understand this from my teacher you made it clear in 5 minutes thank you! Do you have one for phosphorus removal?
At my uni we were taken to a WWTP before the actual course in the curriculum had started , go figure how much the whole class and me understood :D
I´m working in a Wastewater Treatment Unit here in Cartagena, Colombia, and this video is so usefull for training the new operators of this unit. Thank you very much for sharing your knowledge with people around the world.
Super clear, needed this to pass an exam. Thanks !
Outstanding! I'm just recently working at a WRRF and this helped me tremendously! Thanks so much!
Great video, very helpful (especially the problems and solutions at the end) - THANK YOU!
PLEASE CONSIDER making a similar video about Phosphorus Removal in Wastewater Treatment :)
I really enjoyed your video sir. It was very knowledgeable and easy to understand. I wish more videos like this were on here. Thanks -
Very comprehensive and informative, would like to see more of your videos. I am a newbie to the Nitrogen cycle, but I am currently running a project that requires this knowledge. This has been of invaluable help, Thank you.
Perfect lecture on nitrification and de-nitrification. Thank you, Mr. Steven Myers
I never leave comments and had to watch this video for class. This was extremely well put together and easy to understand. Funny graphics too that helped a lot. Great video, great educator
this video is very useful for me to understand activated sludge process. Thank you very much. However, there is one thing that makes me confuse. Can you tell me what autotrophs do during anoxic zone? Because this video shows that nitrification is a very hungry oxygen process.
"Can you tell me what autotrophs do during anoxic zone?" i think they denitrify the water.@2:38
what i don't understand is why do we encourage the break down of nitrate to nitrogen? Why isn't nitrate used as more fertilizer? Why must we depend on the Haber-Bosch process?
excess amount of nitrate in water can cause harm to aquatic system (eutrophication) and human health (blue skin baby syndrom). The amount of Nitrate in waste water is too small to use as fertilizer, and it is very hard to manage if it exists in liquid form.
And i think the most simple way to make nitrate get out of water is using microorganism to change nitrate to nitrogen. it is reason why we use this method to treat water.
I understand that aquatic life is harmed, what I want to know is the difficulty in concentrating nitrate in the water.
How about centrifuging it out? NO3 should be much heavier than H2O... just saying, if a cheap process could be found, you would be competing with a multi-billion dollar industry, as well as promoting recycling.
NwoDispatcher Nope. Denitrification is accomplished by Heterotrophic (BOD reducing) bacteria. Autotrophs don't do much of anything in anoxic conditions.
This was unbelievably helpful and very elegantly done! Thank you!
I am studying for my CA Grade III and this is a really helpful video. Surprisingly my Ken Kerri book did not include the chapter I was hoping for on this subject so I am glad you provided some good information (and a few parts that made me chuckle).
awesome video on nitrification,it explains the concept of nitrification and denitrification
yeppers
This video is great! explains things in a very simple way and makes this topic easy to understand. Thank you!
Very good video. I've been a licensed, Class A WW and DW operator in Florida for close to 20 years and this is by far one of the best explanations for the Nitrogen cycle I've seen. Well done. I've made it mandatory viewing for the operators at my facility.
Shawn T If nitrifiers are autotrophic then why do they become inactive with the depletion of oxygen ? Aren't autotrophs anaerobic ? Can someone please help me with this ?
@@0Sammystanley0 Autotrophs can use Oxygen as an electron acceptor. so they are an aerobic autotrophs
What the range of dissolved oxygen the bacteria need ??
What an amazing and awesome video .
Without doubt , the best video on youtube about this topic .
I highly appreciated your great effort Steven .
Mr. Myers,
I work on a waste water purification plant and i am also doing a "school".
This is a awesome video,
i profi a lot from it. PLS MORE of that 😊.
greetings from switzerland
This has been the most informative and comprehensive video I've ever come across about NR. Billion thanks to Steven.
One of the best videos out there describing nitrogen removal. THANK YOU
Love the simplicity of the video that fully explain the whole nitrogen cycle and yet maintain full scientific terms and conditions.
Hello,
I have a question regarding the hydrolysis om ammonia in the formation of the ammonium ion. I have found other information on the internet, where this process isnt included as part of the nitrification of ammonia, but where its rather the direct oxidation of ammonia. Im a little confused about this, would you be able to explain to me?
Very informative!!! Specially the problem/solution part! Awesome!
So perfect!!! You just summarised an entire group of my exam. Thank you so much, Steven
thanks for the video, you made it very simple and understandable
design of plant (capacity 3000 GPH) that contains amonical nitrogen 4 mg/l , iron 4 mg/ lt and turbidity 55.2 ntu. need ur reply urgent
Absolutelly perfect! ALL RUclipsrs aquarists doesnt understand whole process and mislead nitrification and denitrification. I think they dont understand it at all. Thank You so much!!!
Very insigtfull and well explained.
Thank you
2:39 is bad, O from NO3 is not used during denitrification. NV is used! NV is converted to N0 = N2. OMG. 🙄O is all the time O-II during this process.
I've had a hard time coming across such a complete explanation. Really helpful!
Steven,
What an amazingly simplified and concise video. THANK YOU for such a helpful knowledge contribution!
I am a young researcher in a german institute for sanitary engineering and i really like this short but informative video. ;)
Thanks for your work, Steven. I'm currently conducting a research on Alcaligenes as heterotroph denitrifying bacteria on poultry waste and your video is so informative, please let me know if there are books or articles you recommend about this nitrogen cycle. Have a good day!
Can't thank you enough for this. RUclips is perhaps the biggest blessing to mankind .
Steven : Excellent presentation.Helped me a lot to understand the process.
Is the process suitable for spent wash treatment from distilleries?
Thank you so so much for this video! It's the best explanation video for me, so far. I've watched tons of vids here on YT, and your video was the one that really helped me absorb every part of the nitrogen treatment process. Please continue making videos like these!
Dear Steven,
very nice and clear video. Congratulations! I would like to use it in an aquaculture course I am preparing here in Chile. Would you allow me to use the video in my course?
shamelessly here in 2019
I am a water engineer!
Nitrate NO3 -> N2 ..... during de-nitrification process ..... does the "Oxygen" really provide the energy for bacterial growth ?
I understood that the energy is generated from a redox reaction that comes from the change in the energy levels of the N not the O
Beautiful video that explain in details, thanks for share knowledge 👍
This video was really helpful for an essay I'm doing - where did you source your information from?
I wish every part of Wastewater process was broken down like this video. Great job.
Thank you for the video. I will also throw in my request for a phosphorus removal video. Thanks!
Does anybody have any idea how many g of DBO are required for heterotrophs to denitrify 1 gram of Nitrate...
isn't possibele to collect the discarded hydrogen for helping the energytransition?
Actually it is not nitrate, but the intermediary product nitrite that causes blue baby syndrome. Nice very informative vid though.
Thank you so much, Mr. Myers! Amazing video :)
I just want to keep my little fish alive not to work in sanitation. Just kidding great video very informative.
Really nice and well explained video, thanks for this! 👍👌
Steve, this is a very good video. Thanks for sharing it. Did you develop this? Is it OK to share it?
Excellent piece of information in this video. thanks so much
This is one of the best lectures I have seen on Nitrogen removal. Danke Schön.
anerobic.....the absence of ....free.....O2, not without O2....
I spent a number of years, in this field and still never got a handle on it......
Its a complicated subject but made so simple and straight in this video. Tons of thanks.
Really simple and understandable .. this is perfect one and i note down all of your words
This helps me understand my aquarium!!
What are the most common species of aerobic and anaerobic bacteria in causing algae dead zones?
Thank you Mr. Myers.
I've significantly reduce the 'excruciating' pain in explaining this to my audience.
So, I told them to view your video at your channel.
Slick, isn't it?
Thank you sir you explained it very easily ❤
It is hilarious how much easier it is to learn this with cartoon representations of bacteria
Exellent explanation , very nice animation and creative editing!!! :)
If we add nitric acid and ammonia to ammonium sulfate, won't it turn into ammonium nitrate?
6:19 is a very important oxygen requirements ratio
very clear concepts and practical insights
Where is this sewage plant? Colorado?
very nice & good job
thank you
Great video, I legit laughed a few times.
Thank you alot that was really helpful , keep posting .
Beautifully explained. 👌👍
Good thing we have those bacteria to do most the work.
omg very nice information for my study
This video is very useful to me thanks sir
Thank you. Great content.
I am working on learning the chemistry of aquaponics and so this video has been very useful to me. I am interested about where you talk about "heterotrophic denitrifiers" that turn nitrate into nitrogen gas which can harmlessly enter the atmosphere. I have heard elsewhere that these bacteria can also turn nitrate back into nitrite. Is this true?
Under what sorts of circumstances would these hetereotrophic bacteria turn nitrate into nitrogen gas and under what circumstances would they create nitrite?
Now I understand what wastewater treatment is about
you have right to impose your science on us
Please Hindi language transfer sir
Wonderful explanation. Very Helpful in understanding the phenomenon. Very effective slides to explain.
A complete course in 12mins
I like at 1.55 when the Organic Nitrogen stored naturally in the little creatures is not included in the grouping 'Total Inorganic Nitrogen' the little brown creatures have tears in the corner of their eyes! Nicely done!! :)
Thank you for your greatest video content. I would like to translate to my country language of this concepts. Therefore I wish your documet of this directions by letter. I wii use this for my students.Have a good achievements.Thank you.
Seriously though, well explained, I've been staring at graphs and reading PDFfiles for an hour trying to crack this.
Thanks a lot I like the explainer. .
this is an amazing video thank you so much
Explained so well. Thank you so much for clearing all my doubts
If nitrifiers are autotrophic then why do they become inactive with the depletion of oxygen ? Aren't autotrophs anaerobic ? Can someone please help me with this ?
Thanks
Thank you so much Steven! I have been searching a source with adequate yet brief information on the nitrification and denitrification process for my research work and finally have found something of real help.
woah , did I just watch the best explanation of Nitrification/Denitrification ?
