What is the purpose of adding alum to water during the water treatment process?

a.to filter and remove large organisms and trash
b.to form flocs that bacteria and other impurities will cling to
c.to prevent bacterial growth
d.to remove unwanted gases

I picked c.

I think it's either b or c, not sure. Acually, now that I think about it, I'm pretty sure that you are right about it being b.

So the answer to ( What is the purpose of adding alum to water during the water treatment process? ) is b.?

Yeah, I asked my friend and she thinks so too, but I'll do more research just to be 100% sure.

Hiiiiiiiiiiiiiiiiii! So it's b. right?

Wait, OMG, I AM SO SORRY- you must think I can't read. You typed that you picked c. and I typed back, "I'm pretty sure that you are right about it being b." Yeah, so anyway, to avoid confusion, #1- I CAN read, and #2, the answer is probably b.
see for yourself if you want-type in "Why is alum added to water in the water treatment process" and it says a load of stuff about the alum forming flocculation.
p.s- Hi back @ u! :')
