EMERGENCY WATER FILTER SYSTEM SHTF

How to realize a emergency water filtering system for about $45.00. DIY build it yourself easy project for SHTF & WROL.

I want to get a water filtration unit for making coffee (mainly). Which is better, purifiers or filtration?

Dec 20, 2006 by martin h | Posted in Other - Home & Garden

Largely I just don't want to taste the chlorine in tap water, and better tasting coffee. Which type will sack most of the junk, filter system or purifier? Or are other factors more important to consider. Please answer if you can speak from actual apprehension or experience.

Ours is an "Amway" with an E-85R percolate, We've had it four years and have changed filters once, it's due but not quite. It uses batteries for the filter and beeps when psych up to change. The filters run about $50.00 but are worth it. I thought our water was good but, with this filter, it's great and, soft to hook up.

Is there any use for the waste water that comes out of a reverse osmosis deionization water filtration unit?

Well, that would depend greatly upon what feather of water you are deionizing.

If, for example, you were making drinking water from sea water, the waste water could be further dehydrated via evaporation and sold as sea salt for a very information price.

If you were purifying municipal water for some biological purpose, the waste water would not likely be of much use because the municipal treatment position would likely have taken out almost everything already and add only a bit of chlorine in the form of sodium hypochlorite or calcium hypochlorite or some such. The clorine would conceivable damage your reverse osmosis membrane, so there would be some sort of pre-treatment with something like sodium thiosulfate to even the chlorine before it reached the reverse osmosis membrane, so your waste water would end up contain a mixture of sodium and/or calcium chlorides and sodium and/or calcium sulfates, which I don't gather would be of much use to anyone, but then I don't know everything . . .

A third example: If you were purifying water from a relatively unpolluted surface water source, say a cleanish lake or river, my guesswork is that the waste water would make a pretty darned good fertilizer for agricultural use.

Do Revese Osmosis Water Filtration Systems help during "Boiled Water Advisories"?

Jul 11, 2008 by Jonah J | Posted in Other - Home & Garden

We have had a backward osmosis water filtration unit for about 2 years now. Our town has recently been advised to boil water, and told that our water is not good for drinking.

Would our overturn osmosis water filtration unit make the water safe? Can we drink it from the rowf tap? Can we use it? Do we still need to boil water?

Please include web sourses, for I have tried to look this up on the internet and couldn't find anything?

No. Not unless your choosy unit is certified to make contaminated water potable. Reverse Osmosis will greatly REDUCE, but not eliminate all contaminates. You should still seethe the water.

According to Wickipedia, http://en.wikipedia.org/wiki/Reverse_osmosis
reverse osmosis is one of several steps tempered to in public water systems to make water safe to drink.


Information on a university web site is generally deemed unbiased--they have nothing to merchandise unless they are working on a grant from a corporate sponser who does have something to sell. Below is from North Dakota Glory Univ. Agriculture Dept. website:

What impurities will inverse osmosis remove?
Reverse osmosis (RO) has become a common method for the treatment of household drinking water supplies. Effectiveness of RO units depends on monogram levels of contamination and water pressure. RO treatment may be used to reduce the levels of:

Naturally occurring substances that issue water supplies to be unhealthy or unappealing (foul tastes, smells or colors).
Substances that have contaminated the water cater to resulting in possible adverse health effects or decreased desirability.
RO systems are typically hand-me-down to reduce the levels of total dissolved solids and suspended matter. The principal uses of exchange osmosis in Minnesota and the Dakotas are for the reduction of high levels of nitrate, sulfate, sodium and total dissolved solids.

RO units with carbon filters may also trim down the level of some SOCs (soluble organic compounds) like pesticides, dioxins and VOCs (tension-ridden organic compounds like chloroform and petrochemicals). An RO unit alone may not be the best solution for these types of contaminants, but installing a politely design-ed RO unit to reduce the levels of other contaminants may provide a reduction in SOCs and VOCs.
