External Heavy Metals/Sulphur/Iron Reduction Cartridge
- Uses a compound called KDF that has long been used in water treatment industry for the removal of Iron, Manganese, and Hydrogen Sulfides
- Utilizes carbon for the reduction of Chlorine, Taste, and Odor
- Is intended for use outside of AlkaViva water ionizers.
As a chemical compound, H2S, is a colorless gas that has a very disagreeable odor, much like that of rotten eggs and slightly soluble in water. Dissolved in water, it forms a very weak dibasic acid that is sometimes called hydrosulfuric acid.
Hydrogen sulfide is found naturally in volcanic gases and in some mineral waters. It is often formed during decay of animal matter. It is a part of many unrefined carbonaceous fuels, e.g., natural gas, crude oil, and coal; it is obtained as a byproduct of refining such fuels.
What are the health effects?
Immediate symptoms from the gas may include dizziness and an upset stomach; lengthy expose may led to loss of consciousness and/or death.
Is there any harm from drinking and bathing in contaminated water?
Although many impurities are regulated by Primary or Secondary Drinking Water Standards, hydrogen sulfide is not regulated. A concentration high enough to be a drinking water health hazard also makes the water unpalatable.
The odor of water with as little as 0.5 ppm of hydrogen sulfide concentration is detectable by most people. Concentrations less than 1 ppm give the water a “musty” or “swampy” odor. A 1-2 ppm hydrogen sulfide concentration gives water a “rotten egg” odor and makes the water very corrosive to plumbing.
Iron is one of the earth’s most plentiful resources, making up at least five percent of the earth’s crust. Rainfall seeping through the soil dissolves iron in the earth’s surface and carries it into almost every kind of natural water supply, including well water.
Iron is generally divided into two main categories:
1) Soluble or “Clear water” iron, is the most common form and the one that creates the most complaints by water users. This type of iron is identified after you’ve poured a glass, of cold clear water. If allowed to stand for a few minutes, reddish brown particles will appear in the glass and eventually settle to the bottom.
2) Insoluble. When insoluble iron, or “red water” iron is poured into a glass, it appears rusty or has a red or yellow color. Although less common in water wells, insoluble iron can create serious taste and appearance problems for the water user.
Because iron combines with different naturally occurring acids, it may also exist as an organic complex. A combination of acid and iron, or organic iron, can be found in shallow wells and surface water. Although this kind of iron can be colorless, it is usually yellow or brown.
Finally, when iron exists along with certain kinds of bacteria, problems can become even worse. Iron bacteria consume iron to survive and leave a reddish brown or yellow slime that can clog plumbing and cause an offensive odor. You may notice this slime or sludge in your toilet tank when you remove the lid.
What are the effects?
Iron is not hazardous to health, but it is considered a secondary or aesthetic contaminant. Essential for good health, iron helps transport oxygen in the blood. Most tap water in the United States supplies approximately 5 percent of the dietary requirement for iron. The maximum contaminant level for Iron is .3 milligram per liter.
Taste and Food
Dissolved ferrous iron gives water a disagreeable taste. When the iron combines with tea, coffee and other beverages, it produces an inky, black appearance and a harsh, unacceptable taste. Vegetables cooked in water containing excessive iron turn dark and look unappealing.
Stains and Deposits
Concentrations of iron as low as 0.3 mg/l will leave reddish brown stains on fixtures, tableware and laundry that are very hard to remove. When these deposits break loose from water piping, rusty water will flow through the faucet.
How do I remove Hydrogen Sulfide and Iron from my drinking water?
AlkaViva uses a compound called KDF that has long been used in the water treatment industry for the removal of iron, manganese, and hydrogen sulfides. This filter also utilizes carbon for the reduction of chlorine, taste, and odor. This filter is intended for use in an external housing before the water enters your AlkaViva (IonWays/Jupiter) ionizers.
