EXPLANATION OF CLEANING WATER:
Getting clean water is not really rocket science. There are three basic areas that have to be cleaned to get good, pure water.
First. You’ve got to remove the parasites. Parasites include Giardia and Cryptosporidium. Cryptosporidium is referred to as an oocyst and it is present in over 88% of all source water in the U.S. Guaranteed it is all over the earth. Crypto creates a flu-like symptom and is very dangerous to anyone with a weak immune system.
Second. You’ve got to get rid of the hazardous chemicals; hazardous metals such as lead and mercury; insecticides, pesticides, radon, chlorine, etc. In this process you also get rid of bad taste and odor.
Third. You need to kill the bacteria and viruses.
Removing parasites, in requirement one, is no magic. This requires filtering down to one (1) micron. At one micron you remove those parasitic cysts. Unfortunately, most municipal systems don’t remove the parasites, and probably can’t. If they filtered down to one micron their systems would slow to a crawl and not provide the water we consume. If fact, the recent Safe Drinking Water Act removed the requirement for eliminating Cryptosporidium because it would cause almost all of the municipal systems to fail the Act. Supposedly, this requirement is scheduled for sometime in the future.
All of Global’s systems filter to one micron.
To reduce or eliminate hazardous chemicals below US-EPA or International-EPA standards, Global uses a proprietary formula of multi-media that grab and hold those elements. Most municipal systems use various sand filtration and flocculation methods. Most water filtering systems use activated carbon; some use another media in combination. Carbon only goes so far in reducing hazards. Carbon is great for removing chlorine, bad taste and odor… and that is what sells most consumers. No one has the formulation that Global created over ten years ago that far exceeds those EPA standards.
To kill bacteria and viruses municipal systems use chlorine. Chlorine kills most bacteria and viruses when dosed heavy enough and it puts most in a holding state if it doesn’t kill them. Quite often you can smell and taste the over-chlorination by municipal systems to accomplish this, making water sometimes undrinkable. Unfortunately, the World Health Organization for years has been telling the world to STOP using chlorine. As was confirmed in a front page article by the Dallas Morning New just this past August 6, 2000, while chlorine has benefits of killing viruses and bacteria, it is probably killing us in other ways by creating carcinogens and sending them down to the drinking public. It is unfortunate because, for the most part, there is no alternative for municipalities, Third World Countries, etc.
Global Water, on the other hand uses several other methods in its systems to kill bacteria and viruses. The primary process that really does kill them is ultra-violet. An alternative is ozonation, and in large systems we might use that process.
The W.H.O. stated that most systems in the world utilize one of the three concepts to purify water. Some systems use two methods. And a very few use two and half concepts. Very few systems actually use all three necessary approaches.
Global uses all three concepts to make their water better than any water you could buy in a bottle, in the supermarket or in a fine restaurant.
Now that covers cleaning water. Fresh water. Contaminated water.
Global systems take out the bad stuff and leave the good stuff.
Sometimes, however, there is some good stuff in overabundance that needs to be removed; and many times there is bad stuff in excess that a standard system can’t fully remove.
For example, an oil spill. The Global systems couldn’t clean an oil spill. But, by placing a separator system in front of the Global unit, we would separate out the oil concentrate in one direction and take the remaining “bad drinking water” into a substantially sized Global fresh water system and clean it up to potability. Residual oil can be pulled out, just not a spill.
If there were too much iron or magnesium or sulphur (etc.) we would take the same approach. Put an attachment system on the front end of the Global unit to precipitate the excess material-metal; pull the excess material out through a separate pre-filter process; and then take the remaining “bad drinking water” into a Global fresh water system and clean it up to potability.
In this same manner we can take effluent from a wastewater system, remove the suspended solids and recycle them back to the wastewater system, and then process the effluent back to potability. This is a true recycled water process.
Salt is another problem product that the normal Global unit would not remove; because salt is good… just not too much. So for higher TDS (total dissolved solids), brackish water or seawater Global would add a membrane system (a reverse osmosis system) to the front of the Global process. Those membranes would remove the salt and the remaining Global system would provide the best tasting, purest potable water.
All of Global’s military and disaster relief equipment, as well as total home systems, follow the complete purification process of removing parasites with 1-micron filtration; removing hazardous chemicals, insecticides, pesticides, radon, chlorine, bad taste and odor with its proprietary multi-media filtration process; and killing the bacteria and viruses with ultra-violet.
Where a municipal system has already used the chlorine to kill bacteria and viruses, a simple water filter for one’s kitchen and bathroom sinks doesn’t need Step Three: the ultra-violet process. So Global combined the elements of Step One (removing parasites) and Step Two (removing hazardous chemicals) into its 1-Micron Multi-Media Filter. This is what every home should have as a start toward pure, potable water.
