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.
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.
Currently in Singapore we have reverse osmosis and microfiltration, flocculation being the later stage of the part. Surprised that it was mentioned here.
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.
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.
5:00; How can water be 'TASTY'? It's tasteless. By the way, the video was great and the only one available on youtube which to some extent explained flocculation.
By saying this apparently you have never tasted and never know the different taste of water from well, mountain river, melted mountain ice, water from RO system, etc...Even tap water the taste will be different depending on the chlorine content in it.
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 ;)
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
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.
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.
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.
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 ?
By the time you get to university, you should be capable of understanding an explanation without a cartoon to help you with it. and you should be capable of reading a textbook.
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?
U explained very clearly perfectly....even a student who's not a science background can also understand..... thanks....keep going 👍🏻👍🏻

so informative.....
Thank u sir

super clear explanation! thanks for keeping it simple.
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.
excellent explanation... thank you a lot.. :) really very nice
"Love that dirty water..." ;)
Got 2nd year chemistry exams today. You just saved me. Thank you
oh my God! this video is freaking amazing
Currently in Singapore we have reverse osmosis and microfiltration, flocculation being the later stage of the part. Surprised that it was mentioned here.
Brilliant explanation sir.....u made me understand every bit of it👍
Making clean and tasty water with cool science!
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.
youre explaining better than my lecturer did haha
thank you. very helpful, well explained.

David Betzman what is the main difference between coagulation and flocculation
Ankit Soni Coagulation is a biological/ Chemical process while the Flocculation is a physical process (mixing).
Thanks for correcting this video. It's upside down.
Sir can u pls help me
I am working on a project
Plz tell whether I'll have to mix both Alum and Ferric for the flocculant solution
@@amruthabhat3925 Dear Amruthavalli, you could just choose Poly Aluminium Chloride, Ferric Chloride, Polyacrylamide, one of them is ok
Great information! Is there an affordable, widely available safe flocculant for household use in the developing world?
really nice work, very grateful for your contribution to science broadcasting.
THANK YOU FOR POSTING THIS VIDEO SIR
Realllllllllyyyyyyyyyy informative
Subscribed !!
Cheers!!!!
ZOOOOOOOOM !!!!!!!1 lol
Thank you for the explanation! Zoooom
5:00; How can water be 'TASTY'?
It's tasteless.
By the way, the video was great and the only one available on youtube which to some extent explained flocculation.
If you're thirsty then it's tasty
when water has minerals in it it can be delicious
By saying this apparently you have never tasted and never know the different taste of water from well, mountain river, melted mountain ice, water from RO system, etc...Even tap water the taste will be different depending on the chlorine content in it.
Can flocculants work in oil
who's doing this is school

Is this really easier/cheaper than making a simple still and burning anything burnable, or even the Sun, for heat?
What happend after some months of using a flocculant? Does the flocks delute again with water? Does this type of gel breaks with time? Thsnks
Really impressive explanation. Sir upload videos like this. Thank you sir so much. I can't appreciate you using words. 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Ohhh Nice! Btw this method is called Loading!✌🏻💕
Yah! Its in my sciene book. 👍🏻😊
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 ;)
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
I live in SIngapore and did not know that. EW!!
Hi! Your video is very good! Is alum a coagulant and flocculant at the same time?
That was a great explanation. I work in water treatment and will share this with others having to give educational presentations.
GOOD JOB!!!! thank you! it helped me for my chemical written assessment!!
ZOOOM!
seems like the flocculants might be toxic too. Alum? Is Chlorine a flocculant?
Nice work with this video. Terrific explanation.
Linseed
So flocculation is the quickest way to disperse colloids ? then its on to filtration ?
Thank you very much.. One of the best lecture l ever seen..
thanks for the information.
greattt such a helpful video (y)
great video. Thankyou :D
What is the 3 ml of flocculant solution that you used in the experiment?
Aluminium Hydroxide
I think I can use this to easily collect clay from mud
excellen5
whip it
zoom!
Waoo...very educating simplified...thumb up!
Hey can you plz tell the concentration of alum solution?
So why would one add a coagulant before a adding the polymer?
i think this is coagulation not floculation
Flocculation is when they float up, right? Just checking.
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.
2.5 grams of Alum in 100ml distilled or tap water for 2.5% solution.
it helps me ALOT !!! thank u :*
thanks for you about this information 👍
great vd
Thank you for the video...
thank bro, was useful
Ms Kelly brought me here
Thanks mister,,
What is the medicine mister,,
Zoooooomm
That's perfect. Thanks!
sir ... but here in your video you don't use a flocculant as you explain it but you just make a rotation ???????
He did
very much helpful..!
Soil water mixed superb yes or no
Whate a gret .......
Great! Thanks :)
Bro can you tell me how to make polymer
Thank you for explaining all this in a fun way :)
So what happens with the tap water from Flint, Michigan?
Would you drink the tap water from Flint?
Best fucking explanation with best illustrations dude. My thumbs up
so beautiful
What is the disadvantage of using flocculant over mechanical filter based on water quality ?
Helpful explanation with practical
Thanks🙂😊
THAT was GREAT! Thanks!
How do I.use it in diesels fuels?
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 work - thanks for such a clean and understandable explanation.
Best explanation ever👍🏻
idk where charles river is lol xD
already did. :)
floc this.
best method of explantion
Amazing Explaination Thank you ❤️

Why my stupid university never use this anime to explain ?
By the time you get to university, you should be capable of understanding an explanation without a cartoon to help you with it.
and you should be capable of reading a textbook.
Great explanation 😊
Very well explained, thanks so much for the help!
What happens if you leave the flocs are left to keep circulating. Will they stay as flocs forever?
appreciated
عاشت ايدك فيديو رائع great work thank u
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?
What is "tasty water" ? Water should have no taste.
I think he said "tasteless" water 😅.
The most easily understandable video I've seen❤️❤️❤️
