Flocculation

[@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.

[@RV_UGGERILAYA]

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

[@AS-ou6fe]

Very nicely done video. Just remember the process of neutralising charges of the colloidal solids is called coagulation. It can be quite confusing because either way, chemicals are added to dirty water and clear (not necessarily clean) water is the result. Coagulation is when particles are caused to cling together (coagulate) by neutralising repulsive surface charges. Flocculation is when a soluble polymer is added which captures colloidal particles.

[@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.

[@lukesaldanha7255]

super clear explanation! thanks for keeping it simple.

[@musenw8834]

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

[@johnmark3450]

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

[@michaelbay6727]

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

[@priscillabenner2085]

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

[@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

[@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.

[@hgld]

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

[@pratikbane5892]

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

[@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 ;)

[@tamassandor478]

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

[@arletteal7944]

oh my God! this video is freaking amazing

[@BBQsquirrel]

Great explanation. As clear as the treated water

[@ryancarlsanchezgulfan7524]

thank you. very helpful, well explained.

[@wisnudin3876]

Thanks mister,, What is the medicine mister,,

[@tiagotiagot]

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

[@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.

[@ramachinzah854]

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

[@ikhlassaufi6065]

youre explaining better than my lecturer did haha

[@movingspirit1701]

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

[@autumn_405]

Thank you for the explanation! Zoooom

[@teozhisen4496]

Very well explained, thanks so much for the help!

[@andyjoubert9410]

Can flocculants work in oil

[@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?

[@sandiec6063]

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

[@user-su8dn5bs2x]

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

[@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.

[@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.

[@azhar47r]

brilliantly explained

[@opaaaaaaaaaaa]

thanks for the information.

[@dannyholley]

Nice work with this video. Terrific explanation.

[@augustezelenyte5339]

Linseed

[@AnurupaRoyMusic]

THAT was GREAT! Thanks!

[@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.

[@amenenourmohammadi1602]

That's perfect. Thanks!

[@ProMode-px1wk]

Best fucking explanation with best illustrations dude. My thumbs up

[@meharunnisak6653]

Soil water mixed superb yes or no

[@nutnut5671]

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?

[@raulduke3237]

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

[@Priya-up3lv]

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

[@dalelitster5228]

Aluminium Hydroxide

[@armandomeza3501]

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

[@BhaiThandRankh_Rishabh]

Great explanation 😊

[@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?

[@BadBeesss]

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

[@JasonYouTube2004]

thank you for the explanation!

[@shathaabdullah4229]

What is the concentration of aluminum sulfate added?

[@arnon-jaya]

oyster, shrimp (filter feeder) maybe can filter water

[@smithaks6578]

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

[@muktarmashukura950]

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

[@themilkmister]

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

[@ek9772]

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

[@HBP7712]

can you make video on flocculation vs coagulation ?

[@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

[@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

[@saniasharma5863]

Best explanation ever👍🏻

[@khanwazir6940]

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

[@ek9772]

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

[@elmumeenisaa2551]

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

[@lesliecarreiro1546]

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

[@daniela.cadena7]

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

[@destro4450]

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

[@colinsavage4502]

Was the control also skimmed and filtered?

[@rusmanization]

Simple explanation - easy understand.

[@jaibhimadevi5805]

"Love that dirty water..." ;)

[@zainabali2062]

Amazing explanation

[@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

[@MyThundermuffin]

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

Can u show complete use of floc

[@themilkmister]

How long does it take for flocs to separate?

[@jezeboy]

Great explanation 👍

[@techtimes1985]

Great video

[@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 ?

[@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.

[@nuedinaktechnologies900]

How do I.use it in diesels fuels?

[@sanchitkawale3164]

how do we sepeate dissolved detergent and soap from water?

[@jebinson3138]

Awesome explanation 😍
