Iron Pre-Filter Data
|
Application: This system should be employed as a whole house application where low to moderate ferrous (dissolved) iron, manganese, or hydrogen sulfide contamination is known or expected. This filter will also remove ferric iron through mechanical filtration, although a sediment filter may be a more cost effective choice. This filter is most effective where iron contamination level is less than 3 ppm (and no greater than 5 ppm) or the hydrogen sulfide level is less than about 2 ppm. While the filter will indeed remove these contaminants when these levels are exceeded, the filter life expectancy may be shortened significantly, and contaminant removal may be incomplete. If a combination of iron, manganese, and hydrogen sulfide are present, you must consider the "iron equivallent" level when determining if this filter will work effectively in your circumstance (see below). Best contaminant removal rates are achieved where the pH is 7.0 or higher, although satisfactory contaminant removal can generally be achieved at lower pH levels (6.8 to 6.9) under most conditions. This filter is not recommended where pH levels are less than 6.8.
The life of the filter depends on the contamination level ("iron equivalent") and amount of water consumed on a daily basis. You can get a good idea of how long a filter will last in your case by using the chart below.
"Iron Equivalent" is calculated as follows: (Iron level) + (2 x Manganese level) + (3 x Hydrogen sulfide level)
If your level of Hydrogen sulfide is unknown (it is hard to accurately test for) and you have a noticeable "rotten egg" odor, assume a Hydrogen sulfide level of 0.5 ppm. If the rotten egg odor is severe, assume a level of 1.0 ppm.
Example: Test results are 0.8 ppm iron, 0.2 ppm manganese, and you have a rotten egg smell in your water.
Iron Equivalent = (0.8) + ( 2 x 0.2) + (3 x 0.5) = 2.7

What types of contaminants are you dealing with?
| Problem |
Likely Cause |
| rusty red or brown staining of fixtures or laundry and/or your water has a metallic taste |
excess iron |
| black staining of fixtures or laundry |
excess manganese |
| rotten egg smell from water |
Hydrogen sulfide (H2S) |
How it Works: Soluble iron (ferrous) and manganese are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. The precipitates are then filtered. Ferric iron is removed by mechnical filtration.

Attention
Cross-Border Shoppers!
Every week, we get phone calls and emails from cross-border shoppers telling us how they regret not buying from a Canadian source. These people mistakenly believed that they would save by buying from a US vendor, but were required to pay extra charges for filters imported from the US. "Free Shipping Anywhere in North America" often offered by US dealers DOES NOT mean that you'll get your package free and clear. Vendors offering this "Free Shipping" deal have no control whatsoever over Canada Customs and its import regulations. Your imported package will be subject to federal and provincial taxes. If you don't own a US$ credit card, your Visa, Master Card or American Express provider will charge you anywhere between 4% and 5% cross-currency transaction fee on your US$ purchase. That's in addition to the exchange rate. If the package was shipped via USPS, Canada Post will charge you $8 Handling Fee for delivering USPS mail. You're really out of luck if your order was shipped by UPS Ground, as you'll be charged a Brokerage Fee. Finally, if you ever need to file a warranty claim, it will take that much longer to receive your replacement part sent from the US, with border delays and customs clearance holds being commonplace. There's no question - buying from a Canadian source saves you not only money, but unnecessary aggravation as well.
AquasanaCanada.com is Toronto based and all orders are shipped via Canada Post Expedited Parcel (unless UPS service is requested), from our Toronto facilities. When we say "Free Shipping", it really means that you'll get your package free and clear, and usually within 2-5 working days, depending on your location.
In addition, we promise you the best after-sale experience you'll ever have. What more could you ask for?
