Flocculation

[@RV_UGGERILAYA]

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

[@musenw8834]

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

[@leobanchik]

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.

[@davidpratt9155]

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.

[@ankitsoni5553]

David Betzman what is the main difference between coagulation and flocculation

[@pinkydepaz1861]

Ankit Soni Coagulation is a biological/ Chemical process while the Flocculation is a physical process (mixing).

[@maishamolepo2216]

Thanks for correcting this video. It's upside down.

[@amruthabhat3925]

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

[@dorisshi957]

@@amruthabhat3925 Dear Amruthavalli, you could just choose Poly Aluminium Chloride, Ferric Chloride, Polyacrylamide, one of them is ok

[@lukesaldanha7255]

super clear explanation! thanks for keeping it simple.

[@johnmark3450]

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

[@priscillabenner2085]

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

[@patrickenright6094]

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.

[@michaelbay6727]

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

[@tamassandor478]

Hi! Your video is very good! Is alum a coagulant and flocculant at the same time?

[@hgld]

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

[@BBQsquirrel]

Great explanation. As clear as the treated water

[@sandiec6063]

seems like the flocculants might be toxic too. Alum? Is Chlorine a flocculant?

[@MarcoHandleidingManuel]

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 ;)

[@pratikbane5892]

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

[@ryancarlsanchezgulfan7524]

thank you. very helpful, well explained.

[@arletteal7944]

oh my God! this video is freaking amazing

[@teozhisen4496]

Very well explained, thanks so much for the help!

[@raulduke3237]

So flocculation is the quickest way to disperse colloids ? then its on to filtration ?

[@rantallion5032]

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.

[@ProMode-px1wk]

Best fucking explanation with best illustrations dude. My thumbs up

[@ek9772]

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

[@leobanchik]

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.

[@tiagotiagot]

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

[@movingspirit1701]

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

[@andyjoubert9410]

Can flocculants work in oil

[@autumn_405]

Thank you for the explanation! Zoooom

[@destro4450]

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

[@muktarmashukura950]

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

[@user-su8dn5bs2x]

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

[@ramachinzah854]

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

[@dannyholley]

Nice work with this video. Terrific explanation.

[@augustezelenyte5339]

Linseed

[@colinsavage4502]

Was the control also skimmed and filtered?

[@filipelollita806]

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

[@leobanchik]

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.

[@armandomeza3501]

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

[@sweeyong7756]

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.

[@ikhlassaufi6065]

youre explaining better than my lecturer did haha

[@risistor318]

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?

[@roadtodivine7638]

The alum crystal is made of KAl(So4), this alum is made of Al2(So4)3. they are not the same, also the alum crystal isnt be used for water filtration. Dont try it

[@rubaalsaeed5790]

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

[@azhar47r]

brilliantly explained

[@themilkmister]

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

[@Shaz8673]

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?

[@ek9772]

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

[@MarufoVega]

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.

[@jgreg1661]

2.5 grams of Alum in 100ml distilled or tap water for 2.5% solution.

[@grjadhav8795]

How much alum will flocculate a six thousand litre water tank?

[@meharunnisak6653]

Soil water mixed superb yes or no

[@wisnudin3876]

Thanks mister,, What is the medicine mister,,

[@BhaiThandRankh_Rishabh]

Great explanation 😊

[@rusmanization]

Simple explanation - easy understand.

[@dreamer2683]

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?

[@saniasharma5863]

Best explanation ever👍🏻

[@shathaabdullah4229]

What is the concentration of aluminum sulfate added?

[@themilkmister]

How long does it take for flocs to separate?

[@videos123444444444]

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 ?

[@lesliecarreiro1546]

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

[@BadBeesss]

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

[@Priya-up3lv]

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

[@dalelitster5228]

Aluminium Hydroxide

[@amenenourmohammadi1602]

That's perfect. Thanks!

[@tubasafdar2944]

Hey can you plz tell the concentration of alum solution?

[@MrAlbertamike]

Thank you for a clear consis video.

[@AnurupaRoyMusic]

THAT was GREAT! Thanks!

[@adityauniyal2682]

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

[@sooverma]

Very nice presentation of the process of coagulation and flocculation. However the distinction between coagulation and flocculation is not made and may be confusing to majority of people who use that terminology.

[@leobanchik]

Great point, Subhash. This distinction was not clear to Mohammad and I when we made the video. After more reading, it is now clearer to me. Flocculation is when colloidal particles clump together (because their double layer is reduced) and they retain their individual identity. Coagulation is when the colloidal particles clump and then fuse together to make a single bigger particle.

[@zainabali2062]

Amazing explanation

[@palak6981]

Extremely helpful.

[@khanwazir6940]

can we use water that is cleaned by alum for drinking.

[@shadimahamud6977]

great explanation

Thanks for this, I wish you were my teacher

[@snndrde]

how much water is given flocculant for each?

[@dineshbabus656]

nice vedio with very detailed and with easy understandability

[@thomasgale96]

brilliant video, thank you!

[@jeewansingh4060]

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.

[@lo1d425]

If you're thirsty then it's tasty

[@asterism343]

when water has minerals in it it can be delicious

[@chopcs1]

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.

[@juliannemora7334]

Really cool video!

[@kaifkhan4919]

Helpful explanation with practical Thanks🙂😊

[@smailhamidatou367]

sir ... but here in your video you don't use a flocculant as you explain it but you just make a rotation ???????

[@mfundosimelanempembeelikhu2714]

He did

[@guest2007]

oyster, shrimp (filter feeder) maybe can filter water

[@dhanyakumar2925]

with the help of this video i got some knowledge.>>>>
