Filtering rain water

[Namremahs]

The water filtering through the sand hopfully is clean from the chemicals.

The water I'm filtering is from rain only and should be free from nasty bacteria.

i would still filter the rain water, with the stuff they put in the air.

@Its Hypnosis, Is it possible to use saltwater somehow? Probably not a fast fix method to get drinking water but as a backup ‘if all else fail’. Keeping salty water in, for example, a bottle with a narrow tube through the cork/cap. And if warming up, the water should condensate and escape thru the hole/tube.

@Mons and It’s Hypnosis,
I really like your ideas/solutions. But since I’m lazy and not yet in a desperate situation...
My solution is coffee/tea filters for filtering out ‘big’ particles. And something called “Purify My Drinking Water”, a pill that (supposedly) makes really dirty water drinkable. I’m sure there are lots of products like these.

Also... putting clean copper in or using a copper container will kill off some germs. (If it’s not a myth) hehe. But I guess there’s a risk of getting an overdose on copper instead. (Oughtta be the same/similar with silver)

Anyways... Thanks for sharing your ideas, solutions and results!

to clean sand sift it and burn it, in a pot (without making glass)
i am working on a 2000 l clean water from rain, almost finished.

Interested to know the way you made your filter. let us know how you go please.
I don't think it is necessary to clean the beach sand by burning it, providing
the sand is coming from a clean place far from towns.
My filter is holding a volume of about 2 litres of sand only and when newly made was flashed out with about 5 litre of water to wash the salt away. While the sand might containing some pollutant from the chem trails, it would be a too small of an amount to be of any concern. Keeping in mind that I am on a boat and need to filter 3 litres of water a day only for drinking and cooking. Fresh water aboard of boats is a precious commodity and must be used sparingly.
If I was to make the filter for a big water tank at home, I probably would use a 44 gallon plastic drum full of sand.

since we still live in house,and not moving i decided to take 2 IBC tanks, made a stand for them. still need to put sandfilter pump in, for cirkulation and removing bigger objects from water (from a pool) smaller blue IBC barrel 60 ltr i think, as the filter, with charchoal in it. but i will put some paintings up og it . but a smaller portable is good to have ,

I've always wondered if ships of old did desal. , even in the sailing era, using solar somehow. whaling ships used their acquired whale oil to power their motors at one stage, but earlier than that. then again, they forgot about vitamin C , lime juice, and scurvy for 150 years.

heck watching the by now jabbed burley SAS types in Medieval Castle one off british doco
the 'bad neighbour' sling shot machine..
enough force there to surely force water through a membrane using human hamster wheels.
I suppose they did not have the membrains for it.

pretty much all these filters don't remove dissolved chemicals, they only remove solid particles, including ones as small as microbes, but still not dissolved chemicals. so i recommend finding a naturally clean source - an unpolluted part of the world - else use distillation i suggest. distillation still isn't perfect, some chemicals evaporate & condense at a similar temperatures to water, and it's a slow, fuel-intensive procedure, but it's about as good as you can do with dirty water short of having a laboratory for fractional distillation etc.

will be hard to find a clean source water, but getting chemicals/oils out of water, not that hard.
it can be done with a simple oil/chemical separator with a friction flow on.
most oil chemicals are are lighter than water. 0,800 to 0.850 gr a liter. water 1L 1 Kilo.

sure, filling a bottle from the middle instead of the top of the source body is a nice trick. still, i hope i never need to rely on such rough separation tricks for removing unknown quantities of unknown pesticides from my drinking water. something like that could be a worthwhile prefilter before distillation though, if means permit

hard to find a clean source water

hard in lowlands, easy in highlands
