Why is alum added to water?
Because water does not like to be alone.
It wants somebody’s company.
No. Alum is added to purify water.
Alum is aluminium sulfate.
It acts as a coagulant.
A coagulant attracts and binds with extremely fine and small particles to form a large particle.
I won’t use it.
But why?
Because it will attract all small insects and make a large insect.
You are just unbelievable.
When a solution of alum is added to impure water, it attracts and binds with contaminants and fine suspended particles of mud, dirt, etc. to form large particles.
Being large, these particles can be removed by filtration, or when they settle down due to gravity, they can be removed through decantation, giving us pure water.

Drinking Nasty Swamp Water (to save the world)

While I’m normally a physics guy, got to give the chemists out there props on this one. Also props to Bill and Melinda Gates for partnering with me on this video. Check out their 2019 annual letter here- https://b-gat.es/2RPpLCc

Summary: I used some powder that has a flocculant in it to make swampy water drinkable. This can be used in situations where people don’t have access to drinking water. Then I met up with Bill Gates and we talked about why we should help poor countries.
