WATER PURIFICATION SYSTEM, Cheap and Effective
Intro: WATER PURIFICATION SYSTEM, Cheap and Effective
SO YOU HAVE an emergency supply of water, but you're not sure how pure it is. Here is an excellent, cheap setup you can easily DIY for purifying LOTS of water. It's based on the Berkey ceramic water element filtration system that's been around for a long time. LOOK ON AMAZON FOR "DOULTON" FILTERS. The ceramic material will filter down to .5 micron (that's 1/2 of a millionth of an inch) and according to the manufacturer will eliminate bacteria like E. coli and salmonella, and parasites like Crytposporidium and Giardia, microscopic impurities that will cause serious health problems and even death. A colleague of mine who has a great deal of knowledge in the area of food safety has studied this setup carefully and I have built a system per his recommendations. My primary system has 3 filters and will be used if I need to purify questionable water. From there, you would dispense the water and add 4 drops of non-scented bleach per gallon, let it sit for at least 15 minutes. This will address the possibility that there could be extremely small amounts or particulate matter, for example if you were purifying water from a creek. The bleach will take care of any traces of impurities, then add the bleached water to a 2nd filter system to eliminate the bleach traces. The result SHOULD BE a SAFE source of drinking water.
Worth mentioning is that as long as you are putting in chlorinated tap water from your faucet, you can eliminate purchasing bottled water, because you will have a product that is far better than some of the water out there. AND as long as you are putting in potable water, this system needs almost no maintenance. If you're using tainted water and the impurities clog the elements, they can be removed and scrubbed with a ScotchBrite under some clear running water, and you're back in business. The elements should NEVER need to be replaced. DON'T USE SOAP on the ceramic elements. I use my 3-filter device for drinking water AND for cooking, and it's really nice to have basically free purified water to cook with and not have to worry about a PUR or BRITA filter that just got 1 gallon closer to needing replacement. This setup will pay for itself quickly for most people.
TWO COMPLETE SYSTEMS needs 4 bottles, 4 elements, 2 spigots, and can be made in a couple of hours if you have all the tools located. Cost for the whole thing is about $150, compared to about $700 for 2 of the large stainless steel Berkeys, and I much prefer the transparant bottles so you can see what's going on inside.
I welcome any comments on this critical survival device if anyone sees anything I have missed. This is the method I will be using to purify drinking water for me and my family.
AUTHOR ADDED: I'M GETTING LOTS OF REQUESTS FOR HOW TO FIND THE FILTERS SO I ADDED A SCREEN SHOT OF THE ORDER PAGE FROM WHEN I GOT MINE FROM AMAZON SO YOU CAN SEE HOW MUCH IT COST WITH SHIPPING. I DON'T KNOW THE EXACT PRICES NOW, IT'S LIKELY THE FILTERS ARE GOING UP, BUT EVEN BACK THEN THERE WAS NO SELLER WHO OFFERED ANY BREAKS ON SHIPPING, AT LEAST NONE THAT I COULD FIND.
Here is a link to the manufacturer of the filters: http://doultonusa.com
HERE'S ANOTHER EXCELLENT LINK THAT navarre1095 FOUND:

THE FILTERS THERE HAVE CARBON INSERTS WHICH LASTS A FEW YEARS AT BEST, BUT THE CERAMIC PART IS SIMILAR TO THE DOULTON PRODUCT AND CAN BE CLEANED AND REUSED INDEFINITELY DEPENDING ON THE WATER SOURCE, FOLLOW THE LINK FOR SOME REALLY GOOD INFO, ALSO THEY HAVE A LITTLE BETTER PRICE ON COMPONENTS FOR A SYSTEM LIKE THIS.

At my home I use a pre-filter 10 micron, 5 micron, then softener with industrial mix bed resin(will last probably forever with residential flows), carbon, reverse osmosis setup with a high efficiency grundfos pump and staged industrial bladder tanks. For my entire home it cost 20 thousand to make a low energy unit that needs filters replaced every 3 years and salt every 6 months but if I wanted to set up a simple tap feed I think the DIY crowd could do it for a similar amount of $$ to what you spent!

You seem the best to answer my questions. I'm concerned if our electrical grid gets hacked or goes down here in the USA do to an E.M.P. Then our water system also will be down. My question being. If that happens. I have a 10.000 gallon above ground pool. Electric or pumps aside. Is it possible to , not cleanse or treat or purify the who 10.000 gals. But is it possible to us it as my drinking water supply and treat it as an as need basis, since it will not be circulating with it's normal sand filter.
Thank You

But I guess the whole assembly should be kept far away from bright daylight in order to not have algae produced in the two bottles. And if you have time enough to wait, one filter element should be enough. The filter elements are designed to last for about a max. of 6,000 litres (depending on the quality of the water beeing purified ("filtered")).
Pratical experience here in the countryside in Brazil is, that the filter element gets blocked mechanical by sediments in the water far from reaching these 6,000 litres and the recommendation in the user guide for these elements is to change them at least after 6 months (but I couldn't find out if this is the max. time of efficiency of the activated carbon, the colloidal silver or the mechanical filter fleece).
BTW: "...down to .5 micron (that's 1/2 of a millionth of an inch)..." The unit "Micron" is by definition the millionth of one meter (take a look at http://www.finishing.com/226/71.shtml )

that last option is actually my primary source of water at the moment as the bloody stupid architect of my old house decided to put the septic and the well on the same side of the house, it's not deadly or anything we've tested it but it takes too long to acclimate to the taste of it to really make it worthwhile, the water from the spring is literally the best tasting water i have ever had, ever. so we got a few 5 gallon water jugs and a stoneware water dispenser for our counter and now we have clean good tasting water.
as for catching water being illegal i find it hard to believe that it'd be enforceable, one big thing to remember about legislation is not just the balance between privacy and protection but also the ability to enforce anything. trying to enforce any kind of legislation like this is a statistical nightmare and really cause more problems than solve.
