APSEd Website: learn.apsed.in/
Enrol today in our site learn.apsed.in/ and get access to our study package comprising of video lectures, study material, practice questions and test series with doubt support for Civil Engineering competitive exams of GATE, ESE etc starting from Rs.1599!
APSEd is an educational platform by IIT Bombay graduates. For queries, you can contact us by mail at [e-mail] or alternatively contact us at [phone]
This video covers the actions that take place during the self purification of streams. It also covers the various zones of pollution including zone of degradation, zone of active decomposition, zone of recovery and clear water zone.
Hello everyone, hope you liked the video. This is an educational platform set up IIT Bombay Graduates with an aim to prepare you for competitive exams like GATE, ESE, etc., and to widen your knowledge in Civil Engineering. You can find our entire playlist of videos in this link : / apseduverse
Help us come up with more content by donating through this link.

Or you can use the ever famous PAYTM Wallet. Mobile number for PAYTM donation is 7836970314
You can donate any amount, even an amount of 50 will help us :-)
Would it make a difference if you donate? How will it help us?
Yes, it would. As you all know, we are taking sincere efforts to complete every subject in it's best possible way. And furthermore, we are planning to come up with website where we can put up study material and solved examples. All this does cost us from digital pads, to mics to setting up a website!
How will it matter or help us if you give only 50 ?
Even the smallest of donation has the potential to come up with more content, and more material. Isnt that useful for you. Also make sure you comment in our channel
page that you contributed :)
Deiwakar Singh was the first one to donate us 100Rs. and we are really thankful to him and it did make us happy!

Very straightforward thanks!

[@saurabhsanju7691]

made easy notes

[@aakritisingh.]

You explain well but dont waste time in writing

[@KajalKumari-qc2rx]

Well explained!!

Sir please make one lecture based on Air and Noise Pollution for GATE and ESE point of view ....please sir 🙏

[@ramavtarpatel2852]

Early please sir

Thanks a lot! Helped me in class today

15:00 Organic matter is stabily ? What does it meam

[@honganggaming]

Well explained indeed

[@sandippatel2726]

In zone 2 left hand side 40% of DO of saturation then how anaerobic process will take place? Should not it be aerobic?

[@spjayalatha]

its anaerobic condition only exist bez it has organic matter so its decreasing the DO level from saturation, whereas after active decomposition organic matter is absent and starts DO 40% increase and gets aerobic condition

[@bhavanikondalaraovelisetti793]

Zone of recovery

[@lalitajoshi5350]

Can anybody tell in sedimentation process on the river bed why does only anaerobic reaction takes place and not aerobic?

[@BLNSB_I]

At the river bed DO values will be very low compared to surface hence anaerobic condition is present...

[@JayantKumar-ev4lk]

Instead of instamojo u should provide paytm no .tht will be more easy to do.

[@APSEDUVERSE]

Yes, that's a great idea and easier way! Implemented it now, you can check in the descriptions :-)

[@Er.Pravinkadam]

Very clearly and finely explained all contents
Good
Thank you sir.
If possible
Can you please write clearly .

[@APSEDUVERSE]

Hey Pravin, glad that you liked the content. Do check out our latest videos where we have improved on handwriting as well. Happy learning :)

[@Er.Pravinkadam]

@@APSEDUVERSE thank you sir

[@AdityaKumar-hc6lv]

sir in zone 2 aerobic condition are prevail because in upper layer more disolved is present

[@APSEDUVERSE]

Initially it may prevail but with time it may be consumed by bacteria and more supply may not be there because mixing doesn't take place between layers. There are several other factors which may affect the presence of DO. If such question is asked you will be given with proper data to mark the right answer.

[@shaikhmohsin9438]

DO in stream is maximum at noon or minimum at noon

[@saihemanthpetluri331]

as temperature increases DO decreases. so at noon DO is minimum.

[@anjalir1075]

Max at noon as photosynthesis occurs in noon onlny....
