I work for a water/wastewater processing company. 100% can confirm this is accurate. Excellent video.
Why did they do this overly conflated system? Why not just boil a big vat of water and turn it into steam, pump the steam to another tank where it will condense and then you just scrape the gunk out of the bottom and the heat kills all the possible viruses ECT. Can a virus even survive on a super hot steam particle?
@@TheAnnoyingBoss While I agree that distilling the water also works, and is nearly bulletproof from a safety standpoint, the energy requirements to boil and cool that volume of water would be massive; we generally flow 5 million gallons or so per day, and we only serve about 70K consumer points (IE: households, not individuals).
We need answers. Please someone confirm this because I’ve been using water bottles and some taste weird. Tap water taste good but can’t take chances due to my immune system
@@MrFrhnba I would suggest taking a sample from your tap and having it tested (And not by the door to door sales folks that want to test your water to sell you a filter system). In some environments, it is possible to have roots break into pipes and possibly contaminate water, while still allowing the pipe not to leak due to the way hydrodynamics can work.
You could also call your water provider and ask for input on getting a sample tested as well. They would likely want to get something like that fixed ASAP if that were the case.
That being said, it could also be the plumbing of the house that is affected, not necessarily the line from the water provider...
Can i ask why the treated wastewater and untreated water cant share the same water system? or he says in the video they almost never share the same water system. and also assuming that the water purification plant is in a lake where fish may be how does this affect them? i am doing an assignment on clean drinking water and your feedback would be extremely helpful
The amount of detail in this video, be it the animation or the voice over is just phenomenal. The video reflects the amount of hardwork the creator has put in. I wish you reach millions of followers soon and the world appreciates your content.
Even better it covers some details most other videos do not without making things too complicated to understand.
Yeah this guy should have millions of subscribers
ive worked in waste water treatment for about 17 years, and have never seen a step by step of how the magic happens so clean and well thought out. this needs to be in every sydney water office as a base to their inductions. amazing stuff. you have gained +1 sub
Wow, this was remarkably accurate without drowning the viewer in unneeded details. These processes are crucial all over the world and we can never let up on doing them right.
👍
Would love to see something like this for trash processing. I know there is a lot of variation depending on where you go but knowing what's "normal" would be nice.
that will likely be at movie length since they are separated at the bin already. multiple complexly different processes

I was working on site for a new sewege water tretmant. It's an amazing process and this video is really accurate!
I’m a water engineer for a city that provides water for 7-10M people (through city services and customer cities which are cities that buy water from other cities instead of treating it themselves) and I can tell you this is pretty accurate. I do have a few comments:
1. The lake is typically not on site and is usually pulled through a network of pipes.
2. In the coagulation, typically an iron coagulant is used.
2. The injection of ozone is one of the most expensive processes in water treatment because ozone is typically produced on site for larger cities, which requires TONS of electricity. This is just a fun fact.
3. I didn’t see him touch on chlorination prior to injection into the public use system. Bacteria can develop in older pipes so some chlorination is added to prevent harmful bacteria from traveling through the pipe network.
Thanks for the additional info!
I'm a water plant operator and we almost strictly use chlorination. Some of our smaller unmanned plants use Sodium Hypochlorite, but most (including the one I am currently manning) use chlorine gas. UV is still kind of being phased in simply because we don't really have any way of knowing whether it truly works in disinfecting as we don't use any means of testing it. We rely on chlorination.
As a wastewater operator this is a great video for those inquisitive individuals who always wondered what happens to water before and after their sink/shower/toilet. Great Job y'all!!! Thank you for this video! I'm referencing this video as a teaching aid!
Excellent work. This is one example of an array of options to treat water. In the US, if the source water is surface water or E. Coli-contaminated groundwater, a “residual disinfectant “ is required which is not shown (such as addition of chlorine or chloramine).
bro you're a beast. these videos are insane. i could only imagine the amount of planning, research, and animation editing it takes to make one of these!
you should make another car one! maybe the hvac system in a car, suspension system, transmission systems, drivetrain/differential system, braking system, power steering system!
p.s i am uploading my next big video tomorrow and i voiced over some of your graphic work threw your website in the description as well. keep it up mate!
:D Always glad to see you in the comments, Buddy, and I'll check out your new vid to see how you were inspired to use my work! I like the sense of community, really makes it more worth it to be creating this stuff.
@@animagraffs should be out 2 pm tomorrow!!
And yeah man you're comment section has alot of good feedback. That's how you know your channel will grow brother 💪
100%. I just discovered this channel and am amazed at the detail and research here. Wonderfully informative.
Why is there a DIVER in the waste water ..?
Can they even see anything?
@@trumanhwmaybe for scale
I'm glad I found a gem channel like yours, hope you grow to the millions subscribers mark soon !
woot woot! LET'S GOOOO
Love these videos. Always to the point easy to understand. So many videos have obnoxious narrators always begging for more subs and "Remember to click that bell!" I don't need anyone "reminding" me to subscribe. If a video's quality can speak for itself, then you've earned my sub, and the first animagraff I watched months ago earned you my sub. Keep up the fantastic work!
First one of these I saw, I hit that button so fast I scared it! These videos are Amazing! ❤
I went on a school field trip to the local water treatment plant. That was 1981. 5 the grade. To this day I remember it as the best field trip I ever went on. I was just amazed at how it all worked and learned so much. Every other field trip was a vacation from learning.
I had a similar experience in high school.
Last year we organized a visit to a water purification plant. I wasn't able to attend in the end, so I'm thankful for this video explaining everything in details with amazing graphics. Thank you so much, incredible work as always!
Really cool topic. Great graphics.
Bruh, I studied Civil Engineering in college and I remember taking Water Resources lecture/lab. At that time, I had a fairly decent knowledge of how this works and can somewhat explain the overall process, but you just helped me understand it even more. You literally gave me the bigger picture while handling the smaller details in a non-overwhelming fashion. Holy shit. Awesome fucking job.
abbreviated version - "If you live in New Orleans, St Louis or Baltimore and DC, the glass of water you are drinking has already been in and passed through seven people." Great video! I spent years upgrading, pouring concrete and expanding the Charlotte Mecklenburg NC water purification and wastewater cleaning plants. I gladly drink tap water daily from our kitchen sink and enjoy it without fear and without plastic bottle waste. The LORD is great and I am 62 and have no liver or kidney or digestive trouble. My mom is 92, has done the same and has no problems with our CM water system. Her problem is soda pop and fritos.
😅
What's your opinion on the supposed abundance amount of chlorine and and fluoride in the water. While it's still relatively small, overtime usage of it can't be good right?
I’m curious how they remove chemicals and heavy metals from the wastewater when they turn it into drinking water.
@@meanuncledavid how do they remove the hormones bruh, and American sure love their drugs.
A lot of people don’t realize how good we have it. Infrastructure is amazing
Truest statement of the century. This video actually made me feel a lot better about how we handle our water
I love how high quality your videos are, it is clear you put a lot of time and effort into each one.
I used to love going with my dad to the treatment plants. My dad had a supervisory role so he would just monitor everything and make adjustments if someone missed them, audits, etc. He let me do a lot of fun shit behind those gates. I learned how to operate a backhoe around 9 or 10 years old. That shit wouldn’t fly at all in modern times.
I actually always wondered how water treatment plants worked, but never searched for it.
This now solves it, and in a visually beautiful and well explained video.
It’s interesting seeing the difference between this and my plant. We use lime softening so our process is quite different. Chlorinate the raw water, add lime and ferric/ammonia if needed into a basin. Then the water goes through an ozone chamber and c02 is added. Then to a filter and off to the vessels it goes where it’s filtered for TOC and color. At the very end we add extra chlorine/ammonia/ fluoride where it sits in our tanks before going out into the PWS. Cool video and well done.
I'd ask you to post more, cause these videos are addicting af, but just imagining the amount of work it takes to just make one I get why you can't. Amazing work, really captivating!
I was thinking the same thing 😂. I want more but the amount and quality of information and animation makes me feel bad about asking or making suggestions. I hope he's making enough money or will in the future from these.
I originally found this channel by looking up how antique mechanical pocket watches work. So far, I have watched every one of your videos and subscribed with notifications. I love this kind of content that shows how things work. I am a visual and hands-on type of learner, and just reading about something and looking at pictures does not click for me. I have to be able to see it in action to properly get a grasp of it, and your videos help me do just that. Thanks for this amazing content and I hope you can continue to do this. I do not know the reason as to why you make these videos, but for whatever it may be, don't make yourself hate doing it by doing it too much to where it is like a job. Go at your own pace and do what you like. :D
Yes, this is my first Animagraff experience. Who is this person who takes the time and care to research and create these? What a resource! Is it altruism or the curiosity about these subjects that propels this work?
One of the best channels on You Tube , WELL DONE !
How wonderful to have arrows to guide us.
The arrow is an indispensable graphic device, here put to excellent use.
These animations are fantastic.
a very well animated video
As a union pipefitter that works at these plants, nice job!
This video is another level not just detail but also head to tail.
Here in the Phoenix area, we have an extensive canal system (thought not as extensive as it used to be) which, in some locations, also serves as a way to discharge waste water from these plants since any added ammonia or anything is actually useful for the farmers who use that water. It can also be sent down drainage canals, which ultimate discharge into natural washes or water ways, or it can be discharged into a catch basin and allows to soak into the ground to join the water in the aquifer. Some locations also use a separate piping system to use this reclaimed water for irrigation of city landscaping.
Amazingly well produced: great animations and commentary pitch perfect. Thank you.
A prime example of an excellent conveyor of information, I love the visuals and the pacing of the video. Now subscribed!
Great: editing, animation, research, voiceover, information and overall vibe! Concise and yet well detailed.
you forgot about the denitrification which comes after this step 10:05 (nitrifiacation= O²+ NH³ or NH4+ -> NO³-) . the denitrification is where nitrate(NO³-) will be broken apart to nitrogen gas(N²) and other endproducts.... it needs to be anaerobic(no Oxygen is present) otherwise the desolved oxygen(O²) will be used instead, of the microorganisms.
this step is quite important because otherwise the NO³- gets into rivers and lakes, which acts as a furtaliser und encreases the algae growth.
It's interesting to see the different modes of treatment implemented in slightly different ways than I learned (i.e. in my Environmental ENG class most active carbons, rocks, and microsands were at the inlet or just after the inlet in drinking water treatment, and the bacteria were introduced in the sedimentation tanks instead of separate aeration tanks for waste water treatment). Many ways to skin a cat and all that.
Wow man. Really awesome stuff. Hoping this blows up sooner. This is very informative and easy to follow
Wow impressive animations and great explanations! I really hope that millions of people get to know you! :)
I was wondering how the water treatment works. Thank you for making this video! I will share this to the teachers. The kids need to watch this. Keep making good videos.
I feel like your videos is why the internet was made.
Internet was made to sell weed and porn. And nothing else
Engaging, informative, easy-on-the-eye, good to listen to!
I really enjoyed this. I didn't know I needed to know how it all works, but I'm glad the youtube algorithm told me I did.
You should know that your work is a piece of art, congratulations!
Great video!
the goat.
I smell a collab brewing! :D
The legend himself approves!!!!!!
I hear a battlefield horn :D
Amazing..
I grew up drinking water directly from the stream fed by mountain melting snow and pooping into a pit in the ground. It is impressive how "development" complicated so much these simple basic functions... Excellent instructional video!
This is my favorite channel in all of youtube. Keep up the amazing work!
Wow. This is a fantastic visual explanation 👏 👏 👏
I once went on a tour in a water recycling plant. We got to see the input and output. The difference was so amazing, especially since it started off quite brown and ended up completely clear.
Very accurate description, down to the correct terminology. I'm a water treatment plant operator. We still use chlorination for disinfection, though UV is used in a lot of wastewater treatment plants, Ozone is used in a lot of water treatment plants for pretreatment to rid raw water of organic material. Great animation.
Are there places where our poo poo has to be shoveled from one collection spot to a truck? I'd hate to have that job.
@@dannydaw59 mate, I did that job for 7 years. The floculated sludge from the clarrifiers has to go somewhere; usually drying beds or a screw press or belt press. In the case of drying beds, you wait until the access moisture drains and re-enters the start of the process, then its shovel time. It sounds worse than it is. By the shovelling stage, its more like ashy dirt. We call it 'cake'. its light and has lost its smell thanks to the nitro bacta disolving the ammonia into nitrogen in the aeration tanks. Old mate mentioned that it is used for fertilizer but thats illegal in australia. We send it to landfill - which sounds bad - but its highly nitrified organic matter so the earth loves it. I work with drinking (potable) water now but waste water is way more fun and technical.
I'm "baffled" by the amount of detail.
This is great stuff! You're a great creator for sure, keep up the good work!
Excellent job. A true professional in graphic design with an impressive teaching style to teach various subjects.
Excellent video!! Great overview of the process and the visualization is perfect.
I am an architecture project and my senior year project is a water treatment & research center and this helped me a lot
Great video. You summarized everything in just few minutes, which was very nice to watch and simple to understand. Thank you
Fascinating video and very thorough - thanks Jake!
Great subject, great animation and great explainations. Please, keep doing more.
Brilliant work and really clear explanations! You'll be huge in no time!
Beautiful great illustration. Thanks
What a brilliant work, BIG THANKS!!
Great stuff. Also - chlorine is often used as the disinfectant, rather than Ozone or UV light.
I work at a plant in California we use all 3
Really great video! Another important thing to mention is that many times the water going back into the river after treatment is actually cleaner than the river water itself.
This channel is amazing. Love the most recent video on 18th century ships. Keep up the good work, thank you for teaching me so much! My mind has been blown many times, seeing just how much goes into some things.
Salute to your work
This take a lot of efforts in all the aspects to give such a precious knowledge in one combined video 🙏🙏
You're a damn genius with animation and video creation. Hope you have an amazing career. Saw the first video and instantly said, "this guy has a lot of talent".
Thanks for this…appreciate the knowledge you are sharing💙
Very well done with the information, animation and narration. Thank you.
I absolutely love your videos please never stop making them
I can't believe how much I've learned from your very few videos. The graphics are beautiful and the topics are explained so even a dummy like me can follow along, You need to make more of these!
But you swam through it. I think that makes you very smart. I would die if I had tried to swim through it like you.
😂, you’re too humble, my friend !
I always wondered how water got purified and what they did with waste water. Now I know! This truly was amazing! I look forward to more things like this!
Thank You Sir.
With your videos we better understand how things works.
Even more we can appreciate now the people who created/ manufactured such things.
Awesome job!!!!!!!! Thank you so much for putting your work, time, talent... into this.
ONE OF THE BEST VIDEOS ON W-W/W I HAVE SEEN....I CANNOT THANK YOU ENOUGH
That was so informative and comprehensive! thank you!
Wow man , such detailed work. Couldn't stop myself from subscribing. Amazed at the technology behind the water we drink and water treatment. Glad to live in a generation of technology
I live on a small island in Canada where it rains a lot and we have a well. I once went to a friends house off island and was shocked to find out that they paid for water just like with electricity and such. I feel so bad for taking my usual long comfortable shower there.
the light tank must look really magically at night with bright underwater shine ripples
Perfect video with excellent detail. Thank you
amazing work, as always. thank you for the content
Probably the best info video I’ve seen regarding anything ever. I work at a power plant with a full water treatment system and this is accurate.
Major “Reading Rainbow” vibes here. Sometimes your voice even sounded like Levar Burton. Excellent. ❤
There is so much to be thankful for. This water system filtration is just one of the many things we should be thankful for. Imagine living in a time where this is not a convenience. How horrible that would be. Thank you Engineers and people behind this magic.
Have you considered having collabotative videos with some other channels? Like, "How does a sky-scraper work" with Fred from The B1M, some civil infrastructure with Grady from Pratical Engineering, how various firearms work, with Ian McCollum at Forgotten Weapons, etc. The guest could maybe interact in some way with your animations as they explain how it works?
I hope your channel keeps growing! Cheers!
I just discovered your videos today and have to say these are on par with any learning videos I've seen. My only critique would be to work on the intro and outro especially. A conclusion statement to me would cap off all the great narration for the project.
At any rate thank you to you and your team for all the hard work and look forward to seeing what's next.
Awesome video., great detailed explanation and the animation is amazing. Congrats.
Awesome information, and thank you very much for sharing, looks like tremendous effort in making it.
This kind of animation is what we need at school
Your animation is simply amazing. 100/100!
Thank you for making this!
Thank you very much for your work! I learned a lot.
Thank you for the trip down memory lane. This video meant a lot to me. You just got a new subscriber.
Nicely done. Thanks for this.
Great video Jake. Seriously well done.
Outstanding Video... THANK YOU!!
This topic has never been more interesting to learn about for me. Thanks!
Thank you so much. Excellent video.
I was mesmerized by the presentation that I almost "forgot" to pay attention to the content! Wow job, thank You!
Heyyy we get a VO! Nice... you're a delight to listen to
WOW!, i had no idea how involved this process was, these vids are a real eye opener. Thank you. I'll just scroll up and smash the 'Subscribe' button. Cheers from Aussie.
He's back!!! Love the vids keep up the great work!
Worked at quite a few of these plants as an inside wireman and boy some of them are very clean for what they are, and some of them are absolutely disgusting. The 2nd one I was at I'd constantly get rashes on my arms and one day I was throwing up violently all over the jobsite. The other ones were as clean as poo can be! Also hear a guy 2 hours north drowned in one of the tanks a while back. I'd imagine that's the worst way to go. You can't swim or float in those tanks they take you straight to the bottom.
Yes Bro. You are totally perfect. Thank you so much for the sharing.
Great modeling, animation, and narration!
