Cheapest possible drinking water purification

>>1229726
nitrates and microbes are probably a bigger problem than arsenic (depends on geology and source of pollution)
have the water tested first before you try to solve the problems

>>1229748
This. Know your obstacles, don't just throw solutions at it hoping one will stick.

>>1229726
Cheap and effective (but doesn't remove toxic minerals like arsenic/lead/etc.):

I have no idea how to build one.

Are you in an area where wells are allowed by municipal regulations?

>>1229726
Uhm.. dug wells are the most dangerous since they are easily affected by surface water and contaminants. Drilled wells depend entirely on what part of the aquifer you tap into. Some areas are bad for arsenic, lead, or just high iron/calcium that fucks with pipes.

The only 100% solution is distillation. But that strips all the good minerals and drinking pure water is actually not good for you since it will strip your body of minerals and salts.

What kind of system do they have? That sort of sets the basis for what you need to be thinking of.

If you are dead set on digging a well, make sure it's not in a runoff or ponding area. You want ground water to run away from your well.

I studied water engineering. Just make sure that there is no pollution uphill from the well. Ground water usually flows pretty much the same direction as if it was on the surface. Also, cover the well to avoid animals falling down or shitting in it. If the well is deep then there should be nearly or absolutely no microbes, just make sure that you make it difficult to pollute it.

If your baby crawls around and falls into the well then the water will be unhealthy straight away and after a few days it will smell and taste horribly and have a discolouration. So cover it up and maybe even build up a structure around it. The best would be to make it completely tight, but at least cover it up and make sure water don't fall into the well during heavy rain. Let it filter through several meters of dirt first.

Sand filters only make sense on surface water. Well water has already been filtered, possibly for hundreds of years.

>>1230528
You mean the old bucket and a rope well system right? Get a wind mill(diy obviously) hook it up to the well, have it sit in large glass container, add drops of chlorine(food grade), UV kills virus' if well water is clear, chlorine prevents algae from growing, now you have water. Best bet would be to get glass container that is coated with a paint/liner that blocks everything BUT UV radiation. That'll prevent mold/algae growth AND kill virus'. Have the water flow through sand in a filtered bucket before going in the everything BUT UV protected glass container if it comes out of your well dirty. No added chemicals, no algae/mold, virus' like legionnaires destroyed.

>drinking pure water is actually not good for you since it will strip your body of minerals and salts
Bullshit. Minerals from water are a much smaller proportion of your diet than minerals from food. Hard water can give you some bonus calcium, but you don't need it if you have a normal diet, and distilled water is perfectly safe to drink. Ultra-pure water stops being ultra-pure as soon as it hits your stomach.

>>1230633
Doesn't work like that, UV-A gets blocked by glass, just spray that glass container with silver reflecting paint, get a UV inline emitter, power it with a solar panel that also powers a water pump with a cheap filter and you are good to go

This thread is pure crystalline autism.

>>1230528
actually no.
lots of iron in the ground here. well water looks like beef broth before the sand filter. after the sand filter, crystal clear.

>>1229726
The cheapest possible would be using the sun to evaporate water and collect it with a clear cover leading into a cistern, but this is a family, so clearly the goal isn't just the cheapest possible. Bite the bullet and get a commercial reverse osmosis filter.

>>1230643
Believe what you want, but you are wrong.
And I didn't say it was not safe to drink. Just that it was not good for you. learn to chemistry

>>1230669
Sand filtration is one of the oldest methods. It filters out large particles and some bacteria. Finer the sand, slower the filter, better the results. But you have to wash the filter (backflow) or replace sand because it will pack up eventually.
Past that you need something to kill the buggos. Ozone can do this, as can UV.
But nothing apart from distillation, activated carbon or reverse osmosis will remove arsenic or other heavy metals.

Though back at Gramps the windmill moved water up to a large wooden/copper barrel. No one died from the water. Oh.. copper is antibacterial too.

Dug wells are fucking stupid since pipe was invented. You can also use stainless pipe if you want to waste money.

If your water table is high enough for a dug well it's high enough for a driven well or multiples thereof (they are convenient).

Pump then distil, problem solved. No one else copy OP since he's a fool. If the gene pool is fortunate his well will collapse and kill him.

BTW if arsenic is in the aquifer you will get it from any well. Some areas of Canada near Cold Lake (the example I know from going TDY there) have so much it's advised not to eat the fish.

Distillation is your solution if you've arsenic issues.

>>1229726
"Cheapest" if this is how you think about drink water it dosent mater, you family is fucked already

>>1230669
Yeah, sure in that case... Iron is generally not harmful though, but it might leave a taste and color

>>1230760
learn to biology. You're wrong. You're claim is on par with saying that drinking cold water is bad because your body uses an extra calorie.
Flow rates say you're right, but human biology says it has no impact other than making your piss negligibly more dilute in terms of vitamins/minerals.

>>1230667
"muh pure bodily fluids" is literally our grandfathers' joke about autistic /pol/tards. some things never change.

What I usually do is have the guy at the paint counter mix in a shot of black. It helps improve the purity of my drinking water and the coverage

Reverse Osmosis Systems

Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.
A reverse osmosis filter has a pore size of approximately 0.0001 micron.
Reverse Osmosis Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);
Reverse Osmosis Systems have a very high effectiveness in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli);
Reverse Osmosis Systems have a very high effectiveness in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus);
Reverse Osmosis Systems will remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium, and lead; may reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous.

reverse osmosis is even purer, but the machine is expensive
Also, it's difficult to find the right size, they typically make them tiny for lab use, or fucking huge for an entire city.

okay, #1 on the agenda: what are we going to drink?

>>1233288
A 50gpd ro unit is not hard to find. They even come with a few gallon storage tank and a little tap to put in your kitchen sink for drinking water. I change my pre-filters every 6 months and the membrane about every 2 years. And that's for a family of six.

Literally the cheapest pure safe drinking water I can get and I lived in Third World where the tap water comes out brown.

Water with as much iron in it to color the water isn't healthy for adults, let alone a baby.

>>1232766
I second something like this. For $200 that's a really good price for what it does. Use that for potable water and only the sand filter for everything else. Hooked up like this.

Ok, so I actually fell down an internet hole and extensively researched this a while ago. The end result is that drinking 100% pure water is not great for you because it is a solvent, and can kill cells in your mouth and leech minerals out of your teeth. IF you have a shitty diet deficient in some nutrients it will be worse because completely pure water will pull some of those with it, but you would already have been fucked over by lack of the mineral your body needs, it would just happen slightly faster.

HOWEVER, water that pure is basically impossible, you need excellent lab grade equipment to keep it from dissolving minerals out of the glass or ceramic or metal it's in, it'll pull shit out of the air etc.
Also, all you have to do to fix the low mineral content is drop a few miligrams of salt into each gallon and take vitamin supplements.
A bigger concern is that distilled water will tend to dissolve air into it, so you end up with slightly acidic water because of the carbolic acid from CO2, but the same thing happens to rainwater.

Actually, speaking of, rainwater is also essentially distilled water that has been poured through the air, free of most minerals except what it picks up from there, so any pitcher of water will get that much within minutes as well.

Yep, so biosand or slow sand filter is 95% removal of lead cadmium zinc etc.

The classic sand filter solution is gravel, then large grain sand, then fine sand or clay, then a layer of mixed sand/clay and freshly burned charcoal. Dump out the barrel every 6 months, wash the sand to get contaminants out, then pack with fresh charcoal and sand.

>>1230768
yep, that'll work pretty well. Copper is slightly worse for you than chlorine though.

>>1230526
You sound german.

>>1233327
Why so often on the membranes? I work in dialysis, and our RO's membranes can last over four years? We replace once you you see a drop below 90%

mechanical process =/= dissolution.
