How do I make a water purification system?

I need to make one for Science class, with only materials that are usually found at home. I cannot add chemicals to the treatment process. No one is going to be drinking the water. The purification system should be able to remove garbage (leaves, rocks, wrappers) and clean the colour of the water, somewhat, so that the end product is a beaker of water that has no garbage in it, and somewhat clear. Like I said before, no chemicals, and no one is going to be drinking it.

What kind of water should I drink?

Some say distilled is bad because it’ll make you more acidic. Others are afraid of tap water because of the heavy metals. Even more, some people don’t like bottled water because of the plastic or because the purification process leaves chemicals like chlorine in it… What should I drink?

How can Bacillus Subtilis be used in Water purification?

I’ve heard [and seen many websites that don't offer enough detail, sadly] that Bacillus Subtilis can be used in purifying water. There’s even a sort of concrete product utilizing this bacteria [and two more] in purifying water. I’m just wondering if:

1) if it is really feasible…
2) if it can do it on its own [I mean no other added bacteria or chemicals. Just simply B. subtilis…

Thank you. :)

I installed a salt purification system for my pool today. Do I still need to put other chemicals in the pool?

The person who cleans my pool weekly says I need to add other chemicals to balance the pool. But, I thought when you get a salt water system you no longer need to add chemicals, except for salt.
