EMERGENCY Water Filtration-->> How To Remove The Radiation From Your Water NOW...as in TODAY!Submitted by Jdayh on Sat, 04/16/2011 - 22:13
Many of you are reading about the high levels of radiation in your rain/tap water. Many of you are researching whether or not your water is safe to drink, bath in, or use at all. Since most/many municipalities are not or will not test for radiation, what should you do?
A-- BUY A YEARS WORTH OF BOTTLED WATER AND HOPE IT WILL LAST!
while this idea may seem like a workable solution, it does not solve the fact that no one knows how long this disaster will last, (nor if there will be another similar one in the future) Plus there is the storage issue, not everyone has access to storage for this much water...
B-- USE A SPECIAL WATER FILTRATION SYSTEM! As you read below this solution CAN WORK FOR ALMOST EVERYONE!
Point of use filtration:
There may be no way to completely filter out all radiative isotopes, some yes, all no (reverse osmosis can remove a small portion).”
However, given the immediate need, we can use the capability that reverse osmosis has to offer to our advantage. This solution below will allow someone to get in their car and go get the needed equipment and install it TODAY!
Reverse osmosis has become the industry standard for purification of bottled water. The process has prefilters which included, sediment and carbon filtration prior to the RO processes. Post filtration includes last stage carbon and ultra filtration down to 3 to 5 microns.
Let us begin with the Kitchen.
The greatest volume of drinking water and water used for cooking flows through the Kitchen faucet. We will begin at the point of highest use.
You want to use an under the counter RO systems, which pipes the purified water up to a separate faucet which will be installed by drilling a hole, or for stainless steel surfaces a punch tool will work, if no pre-existing hole is already present.
Previously, the sump type RO unit, required the manual change out of 10 inch filters, requiring manually taking a special plastic round sump wrench and one by one opening and loading and closing the sumps. This required contact with the used filters which will by change out time be loaded with impurities that the filter has removed from your water over a 6 to 12 month period.
In a radioactive environment a nuclear hygienist working for military or civilian facilities, or NBC training officer with the military, will not advise the physical handling of used filtration media. After 6 months of use it will be hot. In larger operations of scale, while taking on the cleaning of radioactive waste water filtration media becomes so hot, personnel cannot even approach the filtration device, let alone open the sump to replace the filtration media. This was problematic. Then the idea came to produce an encapsulated disposable filter cartridge that would be monitored and removed before it reached dangerous levels. Originally very large cartridges were designed for industry use and required carts to move them. Personnel were adequately suited for exposure levels while working to remove and replenish threshold cartridges. The spent used cartridges were moved to entombment burial sites.
The encapsulated filter technology evolved through three decades until it became available for civilian residential use.
This background on encapsulated filtration cartridges is very important to know in a radioactive environment. To approach filter change in a pre-311 manner will, as time passes, become more and more hazardous. You must avoid opening a sump filtration container, due to nuclear hazard. Opening a sump in your primary food preparation area will surely lead to unintentional leakage and splash on to the kitchen floor, on your hands and body. The longer this event drags on, the higher the hazard, there will just be more radiation accumulating in the filter media.
The RO unit you select must be based on this design, encapsulated filtration cartridges.
Fortunately, and Providentially, this type of RO system based on encapsulated filtration cartridges, is now available for residential home use, and it is under the counter installable, esthetically pleasing and affordable.
Premier RO-Pure, Model WP RO-4
Costco sells the unit for $159.99 in most areas.
You might want to add a permeate pump to the unit, this will save a lot of water in the long run. Or buy the unit with a permeate pump already installed from US Water, who is the largest distributor of Watts systems in the US.
Please remember that this is is an emergency response recommendation. Better solutions exist, but under the present circumstance we all need help with this problem now! Costco is a drive away. Buy one for your kitchen and if you can afford it, one for each bathroom and one for your business. You can use the water to wash your face and brush your teeth with, as well as a late night drink of water for the kids.
Cartridge change is easy and safe, with no spill danger during change out. It’s so easy to do, just twist and press the button, dispose of the cartridge in the trash when it is time to change out. The frequent regular 6 month change out will keep radiation levels low.
RO will remove 92%+ of uranium and preliminary unpublished tests seem to indicate the other radioactive particle removal at about the same rate.
What about the other 8%?
Good question, now the other part.
Water finishing filtration:
Many minds have grappled and are now grappling with this problem of how to remove the remaining 8% or less, you may get up to 96% removal depending of several factors, such as filter life. New and freshly installed filters and RO membrane will perform better that an older one, producing a cleaner product.
So we need to remove 4% to 8% of contaminate from RO finished water. How do we do that?
It has been suggested that the RO water be run through a second time through a secondary post RO systems, which would yield a reduction of contaminate reduction of 50%, assuming filters and membrane at peak efficiently. But this is speculation.
Distillation has been suggested, however radioactive Iodine-131 was found rising in the steam emissions from Fukushima. This isotope can ride on H20 in various states, such as steam (gas state), rain (liquid state) and snow (solid state as ice).
A resin based, DI system seems to be a better solution to purify out the remaining radiation. A dual resin two tank system may work. Resins pull out the radioactive particles using electrical ion charges on the surface of resins contained in the filtration media. The best resin based DI systems is under investigation and testing.
But what can we do now to remove the 4-8%?
Fortunately and providentially, after decades of development, ion exchange tech is now available for home use.
A five stage filtration system, compact, transportable and affordable is now here.
It is the Zero water Ion Exchange filter.
Order through Amazon, a Zero water Pitcher, order at least two. It comes with a filter enclosed in the box. You may enjoy having two because when you are using one to pour the other is refilling. Turn on your RO faucet, fill the top of the pitcher, wait and there you have water with Zero particles per million. The ion exchange process will remove a good portion of the remaining particles within the water. By filling your Zero water pitcher with RO water you will extend the life of the ZeroWater cartridge. http://www.amazon.com/ZeroWater-ZD-013-Filtration-Electronic...
The company has not tested their filter with radioactive water, and makes no claims that their product removes isotopes, such as Iodine-131, etc.
So there you have it, perhaps the best shot at solving the problem today, using what is available, a MacGyver -like solution.
There are better answers for sure, but none as readily available as a drive to Costco and on line order from Amazon.
