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.

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.

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.

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 ?

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.

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?
@leobanchik
@leobanchik 11 жыл бұрын
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.

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.
