We just got our well dug and want to keep the water pure and not have to worry as much about a bacterial or microbial issue. We would have a pre-filter system, then the UV or ozone, the booster to the house, then a post filter. I know we will still have to monitor the storage tanks themselves as well as treat occasionally, but really want to know we are pumping clean water into the home.
TIA

In general:
- UV is good for killing what goes through the UV lamp assembly, but has no residual effect downstream - slime and bacteria in a storage tank will not be killed.
- Ozone is good and will have some residual effect down stream and is very effective at killing bacteria, providing you feed the right amount
- Carbon filters take out taste and organics, but do nothing for heavy metals
- Sediment filters only take out suspended solid particles - sand, insoluble metals, nothing dissolved like minerals, salts, etc.
With a well, most of the bad bacteria aren't typically a problem. It's tough to dose chlorine/ozone effectively, so I think I'd go the UV route if I were you. Chlorinate the well at the beginning, let it sit 24 hours, then flush it well.
