New filter invention

What I like to see is the fusion of a pump filter and UV technology — a compact and simple pump filter with a carbon element that clarifies water, removes the bigger baddies like protozoa and eggs, and improves water taste. Then , UV zapping to treat the smaller bacteria and viruses as the filtered water travels the remaining length of tubing to our water bottle.

Benjamin, I agree completely! A manual pump (or siphon) that does not rely on batteries, plus UV in a compact package would be nice.

The UV part of any filter pump would have to be located in the collection vessel to give the UV time to work.

And still the collection vessel would have to be swirled during UV exposure to make sure all pathogens are subjected to the light.

why not use a steripen with an activated carbon filter and 1 to 1/2 micron prefilter. that outta take care of what you want. The prefilter will make using the UV more effective, the uv kills, the carbon traps/cleans. Im working on incorporating powdered activated carbon instead of granular for my setup, should clean much better. Also gonna buy some high quality ac from calgon in bulk, stuff that removes just about everything.

Using UV and filter is like belt and suspenders

unnecesary

and has already been discussed, it's not clear it needs to be treated at all

so that would be belt and suspenders while you were in a weightless environment

doesnt do anything for taste/color. Large particulates also can impede its effectiveness.

I'm thinking that by first clarifying the water and blocking out the bigger and harder to kill stuff (protozoa, etc.) — so that the UV only needs to kill/neutralize the teeny-tiny stuff in clarified water — treatment time can be cut way down. Maybe a manufacturer can add in a short, compact and tortuous path within the unit housing to zap the water with UV — and still make a reasonably light and compact filter-UV combo?

In other words, a simple filter that blocks only the big stuff can be made really light and small — to allow more space for the UV part to work? Any tinkerers out there willing to give this a try?

I made a 1 micron prefilter. I scoop water, hold the filter under it, align it over my dirty platy and the water runs through it into the platy. Works great but its not tiny like you want. You could cut a small disc of it and place it inside of another filter.

Howdy Ike:

I recall seeing that 1-micron filter. Can you tell me where you bought yours? Also, how's the flow rate when you pour water through it? Is it fast like a metallic mesh coffee filter, or slow like a paper coffee filter?

If your talking soley about the 1 micron filter material, a user named dudadiesel sells them on eBay. The flow is phenomenal, practically no restriction. In a thread in myog recently I posted 2 videos on making your own carbon filter.

Thanks!

I ordered the BULK 1 micron stuff, not the bags. It was like a huge sheet folded up. Im ordering the 1/2 micron next, and switching to the powder to improve my filter.
