An under the sink RO system as an option IF it can remove radioative contamination is great but an under the sink system assumes thaty you will always have sufficent water pressure to use the system. So even if you have an undersink RO and it does remove this type of contamination I would have a back up system. I don't see why you could not build a three bucket system similar to the two bucket system but adding the zeolite as an added layer of filtration. If you wanted it compact you could just have smaller containers.

The reason for this water system to begin with is because no matter how you slice it we will be dealing with more radiation. The amounts and specifics of the level of contamination can be debated but still isnt going to change anything. We are seeing it already, and until they get those reactors stopped it continues to this day. Best case scenario from TEPCO is MAYBE the end of the years, but some say thats impossible.

Back to water filtration.

I also want to filter the source not just a singular sink.

Thanks Pan, I read that article it says that RO does not capture gaseous Radon, etc..Iodine 131 escapes as a gas.

However, EPA designed its recommendations for the contaminants typically found in municipal water systems, so it doesn’t specify Iodine-131 by name. The same document goes on to say, “Reverse osmosis does not remove gaseous contaminants such as carbon dioxide and radon.”

Iodine-131 escapes from damaged nuclear plants as a gas, and this is why it disperses so quickly through the atmosphere. It is captured as a gas in atmospheric water, falls to the earth in rain and enters the water supply.

This is what happened in Boise, Idaho, where iodine-131 was found in rainwater samples last week and then in drinking water samples a few days later.

Also, I am the last person that will ever trust a govt. never happen, everything revolves around making money, not helping people stay healthy. It would cost money to revise and change what they already have on the books, also them raising the levels right after Fukushima also tells me they are FULL OF ****.

ROs do about 50 gal a day. That covers your cooking, drinking and ice. Use good cartridge filter bank (2 or 3) for the whole house. If you talk to Bobzilla ask him if eh put me on his ignore list I can't even get on the prospecting group or contact him. thanks

Bob is not taking messages from anybody. Leave a message in the prospecting groups area, or here or the Fukushima thread. think he checks it still.

If you have that problem destilling or maybe just boiling the drinking water after the ro would be the best I think.

You know how some people like antiques? They have enough money to buy brand new but prefer the sofa made in 1880. I'll give you an antique answer from 1957-8; can't remember the exact year.

My elementary school had a civil defense speaker who gave a talk about surviving nuclear war. It was quite a big deal; both my parents went and the lunchroom/auditorium was filled.

This expert said if we needed to drink water from a stream, pond, etc., we should put the water in a glass and then put in a handful of dirt. The dirt would pull the radiation to the bottom, and the water left on top would be safe.

I was suspicious of this at the time; it seemed to me the dirt would probably have radiation in it, too, so wouldn't it leave radiation rather than remove it? No real answer from our government expert.

Like I said, an antique answer.

Awesome!

You gotta post pics or video or it didn't happen dude :. If you decide to add activated charcoal, the pet stores typically have that in half gallon milk cartons for like $10-$15. Today at the pet store I even saw something that may have been a Zeolite/ activated charcoal mixture in half gallon milk cartons. The ingredient list didn't say what the ammonia absorber was.

I've been thinking of doing something similar using a ceramic aquarium air stone as the final filtering stage after the Zeolite.
Ceramic aquarium air stones are pretty tight. Check out the flow rate in this example:
YouTube - DIY Emergency Drinking Water Filter

I'm no sure the pet store charcoal is safe I bought some just for that purpose and the water tasted funny afterword.
I like the idea of the air stone:thumb::thumb::thumb: though you might want to stock up as they would clog up at some point

I just got back from both Home Depot and Lowes, I am going to wait till monday before I try this, they want ridiculous prices for a piece of PVC, I am going to a plumbing warehouse but they are closed today...

I did see a few water filtration systems there, seems like you could just modify a current setup with Zeolite. I'm not sure reinventing the wheel here is nessesary.

I've got a couple old SS water fire extinguishers I thought I'd use as they are good for at least 150psi. I'm thinking filling one with zeolite and the other with activated charcoal. from there i have a multi stage I put together filter for drinking water.
I found a source for food grade AC at 1-800-733-7263 minimum is 25lbs and last time I checked it was 75/ bag, probably more by now.

Here's my multi-stage

effluent handling?

Maybe try to look under remove radiation from water I saw it at 2 or 3

places. There are two concerns with a portable ro. One is It takes I think 3

gallons to make 1. I'll be working with a well so that's not a prblem. I'm sure I

can find use for the waste water.

The second thing is that you have to force water through the system

under pressure. I am going to use a 12v pump into a pressure tank, then into

the ro.

Pan

Some considerations to take into account with RO systems:
They can be sized to output anywhere from 5-25 gallons per day for under counter systems up to hundreds or thousands gpd for whole house systems (which usually require a large storage tank to buffer production with use)

As others have mentioned your membranes will last longer if the input water is cleaner, have good prefilters or you will quickly foul the membrane.

RO systems are not terribly efficient; generating 1 gallon of RO water will produce 3-7 gal of waste water. The waste water is a mix of the original incoming water + the contaminants that were rejected by the membrane. If you are filtering out radiation, heavy metals, bacteria, virus, cysts, etc, what will you do with the effluent water? It may be fine for flushing toilets with, but I'm not sure I'd be comfortable irrigating my crops or washing clothes with that type of water. Perhaps have a zeolite system or other type as others are discussing here as a secondary filter system either to filter the effluent before other uses. Or put one of those inline before and use the RO for the final polishing filter.

Thats exactly what I was looking at at lowes, these canisters types aren't terribly expensive either.

Thanks for the AC connect.

I Know people who have these dosimeter stickers you can buy from ki4u.com not sure if it would work because it would read all radiation but I think at 5 bucks a piece they might work on the side of one of these canisters of PVC sch40 pipe

The systems I've sold have been 50 gallons / day. I see no reason for a whole house system. Although a bank of good cartridge filters on the line in would be a good idea.

The toilet is what I had in mind.

yep a broken record.

use zeolites, activated carbon, and other natural substances will help rid radiation. the more stages of filtration the better quality of water, more structure/energy can be added back to water. try to mimic earth best you can to get best quality water,

or get water from naturally force fed spring and go from there.


paul stamets has successfully cleaned contaminated(bacteria) water coming onto and leaving his property with mushroom innoculations in the water ways coming and leaving the property

This Paul guy is a genius. I have a nutritional supplement company in the works and plan on ordering from him for key ingredients.

 

[ShellbackBill]

All you need is a common particulate filter. A few layers of cloth would probably do the trick.

From
http://www.fcs.uga.edu/pubs/current/FDNS-E-34-3.html

Filtering will also remove radioactive fallout. (Water itself cannot become radioactive, but it can be contaminated by radioactive fallout. It is unsafe to drink water that contains radioactive fallout.)

And yes that filter will contain radioactive particles, now concentrated into a small space. Get away from it as quickly as you can. Or build some kind of shielding around it.

Maybe build your filter into a barrel of sand. Or even a barrel of water.

 

[hopnchop]

Been rolling around the thought of being able to filter radiation from my drinking water. How might the average citizen best accomplish this with items they can get their hands on easily?

What ideas do you all have?

Well now I don't know I'd be so quick the filter it. After all, I might end up with some neat super powers out of it.:thumb:

 

[Happy Joe]

A. No need to worry unless an all out nuclear war occurs, with attendant fallout.
B. In that event there is no need to worry if you have a reasonably deep well (more to worry about from chemical/fertilizer contamination in this case).
C. A reasonably effective particulate filter can be made from commercially available filters & housings, including a carbon stage that will filter particulates in the 1/2 to 2 micron range. This would likely be effective against even some viruses and could likely be used for biologically contaminated surface water (with a pump to push the water through the filter).
D. There are many levels of water treatment ranging from none through water softeners to filters to reverse osmosis, all have some advantages in some situations.
E. If you are truly paranoid, you can deionized and triple distill your water to remove all but the chemically pure H2O (although this runs the risk of removing necessary minerals from your diet). If you actually seriously consider this then I recommend that you see a professional therapist.

For the only moderately paranoid just install a 2 stage particulate/carbon filter in your waterline and service it regularly. A handy person could probably do it for less than $100, although you should check your water first to see if it actually has a problem that filtration will fix.
If you are worried about your children/grandchildren because of the reactor problems in Japan, don't; they will probably not get as much radiation as we were exposed to in the 50s during the Nevada nuclear testing.

The best thing to do when worried is to educate yourself on the actual danger and possible consequences of any problem. Use information from reliable, non agenda based sites not places like here where many have apparently stopped taking their medication and/or are promoting panic because they are ignorant, poorly raised children (that think its cool to scare people).

Enjoy!

Are you guys too cheap to spend $300 - $400 to put a reverse osmoses filter under your sink? This is a no-brainer. I have

had one filtering my cooking/drinking water and ice for 12 years. We have hog farms within three miles and don’t drink water

that isn’t ro filtered. It will take any radio active particles out.

Pan

how much energy does a reverse osmosis filter need to do its job???

as i understand it you need to have a pretty high pressure to filter through its semi-permiable membrane (depending on what is in the water)... most household pipes have water pressurized to 10psi, but for a reverse osmosis membrane to work on sea water you have to overcome its natural osmotic pressure which is about 390psi!!!!! this would require a pretty substantial energy drain (not to mention some stronger pipes) to attain the appropriate pressure.

I agree, the RO system is good under current circumstances, but I dont see it as a viable filter if ANY of the variables get changed.
