U explained very clearly perfectly....even a student who's not a science background can also understand..... thanks....keep going 👍🏻👍🏻

Great vid, thank you! We just bought a Lovibond flocculator today in work, I set it up and we will be using it over the next few wks. Great to get a simple overview as to what's it all about.

Currently in Singapore we have reverse osmosis and microfiltration, flocculation being the later stage of the part. Surprised that it was mentioned here.

Great work - thanks for such a clean and understandable explanation.

super clear explanation! thanks for keeping it simple.

Hi Priya, we used alum (aluminum sulfate) flocculant. If I remember correctly we used a hydrated form: Al2(SO4)3•16H2O. We made a 2.5% solution by volume with the flocculant and potable water.

really nice work, very grateful for your contribution to science broadcasting.

Very well explained, thanks so much for the help!

Got 2nd year chemistry exams today. You just saved me. Thank you

Thank you for explaining all this in a fun way :)

oh my God! this video is freaking amazing

Great explanation. As clear as the treated water

thanks for the information.

thank you. very helpful, well explained.

Waoo...very educating simplified...thumb up!

That's perfect. Thanks!

Thank you very much.. One of the best lecture l ever seen..

Brilliant explanation sir.....u made me understand every bit of it👍

Alum and Ferric are cationic coagulants, not flocculants. Cationic coagulants neutralize the net negative charges on the suspended solids which allows the colloidal particles to naturally join together as you demonstrate. Flocculation, if necessary, follows coagulation and is done with very high molecular weight, long chain polymers.

THAT was GREAT! Thanks!

a very good explanation, i was wondering what it meant. I got past the term by a yeast for beer, became curious and used the search term on youtube and got a clear explanation. my beer will be much clearer now, hope my mind stays clear too ;)

THANK YOU FOR POSTING THIS VIDEO SIR Realllllllllyyyyyyyyyy informative Subscribed !! Cheers!!!!

Thank you for the explanation! Zoooom

GOOD JOB!!!! thank you! it helped me for my chemical written assessment!!

excellent explanation... thank you a lot.. :) really very nice

brilliant video, thank you!

Is this really easier/cheaper than making a simple still and burning anything burnable, or even the Sun, for heat?

Thank you a very easy and simple explanation I was reading psm and this came in rapid sand filter

Great information! Is there an affordable, widely available safe flocculant for household use in the developing world?

Thank you for a clear consis video.

Thank you for the video...

So what happens with the tap water from Flint, Michigan? Would you drink the tap water from Flint?

The most easily understandable video I've seen❤️❤️❤️

Amazing Explaination Thank you ❤️

brilliantly explained

heartful thanks

Nice work with this video. Terrific explanation.

thanks for you about this information 👍

When you add flocculent to precipitate out iron from a pool how much aluminum is left in the pool? How dangerous is it to ingest aluminum if you swallow pool water with leftover aluminum?

umm finally i'm learning some science. thank you. but i have a question, is there any flocculation method for sea salt water? how can we make sea water drinkable?

Hi. What happens, for example, if i use this method to flocculate water with a clay content ? I´m interested to know about the flocculate material instead of water, the final material is completly diferent from the original one (after dry) or the material turn back to clay powder after dried ?

That was a great explanation. I work in water treatment and will share this with others having to give educational presentations.

Was the control also skimmed and filtered?

Agreed. I've heard of the like likes like phenomena to, so I am sort of at a loss because it seems that colloids can attract and repel?

Amazing explanation

Extremely helpful.

i tried flocculation once but my mom caught me and said i would go blind if i continue. needless to say i stoped when i needed glasses.

Great explanation 👍

Helpful explanation with practical Thanks🙂😊

Awesome explanation 😍

This is the best video i have found so far thanks👍👍👍

great explanation

Making clean and tasty water with cool science!

"Love that dirty water..." ;)

Really cool video!

Really impressive explanation. Sir upload videos like this. Thank you sir so much. I can't appreciate you using words. 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Thank you

Do you know the dangers of ingesting a little bit of aluminum?

Flocculation works by precipitating colloids that are larger than the dissolved ions that are in seawater. To remove these ions requires a distiller, as NetView2011 pointed out, or use of other methods including reverse osmosis! Not all desalination plants are distillers. In fact, according to the International Desalination Association, about 60% of the world's desalinated water in 2012 came from reverse osmosis, which uses large pumps to force water through arrays of special membranes.

great video. Thankyou :D

it helps me ALOT !!! thank u :*

Simple explanation - easy understand.

Good explanation.... Keep it up👍👍

awesome!

Can u make video on inert pair effect and inter electron repulsion

There are predominantly two forces that work between the colloids. A repulsive force and an attractive force. The repulsive force is an electrostatic force and works just like two magnets of the same polarity coming into proximty. The attractive force is called the London attractive force and is due to quantum fluctuations.

appreciated

Great! Thanks :)

How long does it take for flocs to separate?

I didn’t know you could use something like Alum for this!!! I used to use Alum to make crystals when I was a kid! ^^ So...after flocculation using alum, skimming and filtering the water a few times, is the water safe to drink?

oyster, shrimp (filter feeder) maybe can filter water

What is the 3 ml of flocculant solution that you used in the experiment?

nice vedio with very detailed and with easy understandability

Best fucking explanation with best illustrations dude. My thumbs up

how do we sepeate dissolved detergent and soap from water?

Best explanation ever👍🏻

Great video

can you make video on flocculation vs coagulation ?

Thanks so much

What is the concentration of aluminum sulfate added?

Really amazing

So about how many mg of Alum did you put into the beaker. The volume of the solution was mentioned but not the concentration of the solution or mass of alum.

Thanks

if well water is high in ferrous soluble iron. can i use alum to make it fall out? i have used h202 to oxidize the ferrous water, it turns into a ferric hydroxide floc, however it takes the solod floc 6-8 hours to settle to the bottom. is there a coagulatant that i can use to speed up the process so that it settles put faster? cheers.

great vd

谢谢 好视频

What happens if you leave the flocs are left to keep circulating. Will they stay as flocs forever?

very much helpful..!

How is the alum solution prepared

What chemical you used

special thanks

youre explaining better than my lecturer did haha

عاشت ايدك فيديو رائع great work thank u

Hello Can I ask do you know exactly the difference between TOC , DOC , Turbidity? could you help me with this Humic acid and fluvic acids are a cause of turbidity or DOC? Thanks alot

Can u show complete use of floc

very good explaination

fantastic

Crystal clear ❤❤

What is the disadvantage of using flocculant over mechanical filter based on water quality ?

So why would one add a coagulant before a adding the polymer?
