BIG BLUE WATER FILTER CARTRIDGE KDF85/GAC 4.5" X 20" - Iron/Sulfide Reduction

BIG BLUE 4.5 X 20" KDF85/GAC WATER FILTER CARTRIDGE: Coconut Shell GAC & KDF 85 media.

KDF 85 Medium Removes or reduces iron and hydrogen sulfide from municipal or other water supplies. Also controls scale, bacteria and algae.

iron / hydrogen sulfide reduction filter contains a combination of KDF85 media and coconut shell activated carbon. The KDF85 effectively reduces dissolved iron and hydrogen sulfide odor over a wider pH range than possible with standard oxidation filters such as manganese green sand, thereby protecting your plumbing system including toilets, bath tubs and showers, and appliances such as clothes washers and dishwashers, from unsightly staining and odor. The activated carbon removes organic contaminants to substantially improving water clarity, taste, and odor. It does NOT add any harmful chemicals to the water, making it completely safe for drinking water applications.

Note:

**Hydrogen sulfide concentrations exceeding 7 to 10 ppm can be removed by injecting an oxidizing chemical such as household bleach followed up by filtration. The oxidizing chemical should enter the water upstream from the storage or mixing tank to provide at least 30-45 minutes of contact time between the chemical and water. The length of length of the holding time is a function of the chemical dosage, tank configuration and water temperature. Sulfur particles can then be removed using a sediment filter and the excess chlorine can be removed by activated carbon filtration. 

If test results indicate that bacterial contamination is occurring, shock chlorination or disinfection is the most widely suggested method for initial treatment. Shock chlorination (disinfection) is the one-time introduction of a strong solution into the entire water distribution system (well, pump, distribution pipeline, etc.)

When to Shock Disinfect the Well:

Shock chlorination (disinfection) is recommended when lab results indicate a presence of bacteria upon completion of a new well or after pump replacement or repair, when the distribution system is opened for repairs or maintenance, following contamination by flood water, to control iron and sulfur bacteria.

Shock chlorination (disinfection) is recommended in these circumstances to ensure that bacterial contamination is controlled.

Note:

This cartridge should be used where low to moderate ferrous (dissolved) iron or hydrogen sulfide contamination is known. This filter is most effective where iron and hydrogen sulfide levels are less then 5 ppm. Best removal rates are achieved where pH is between 6.5 and 8.5 and where water contains some dissolved oxygen.

Note:

Selecting a water treatment system begins with water test results from a certified drinking water testing lab. Such test results should be compared to the water treatment product specifications to ensure that the treatment system being considered is designed to treat:

  1. The substances you want to treat
  2. In the concentrations at which they exist in your water.

There is no one-size-fits-all water treatment technology that addresses all water quality problems. In some cases, one treatment technology may meet all your specific needs. In other cases, you may need a “treatment train”—a series of treatment technologies in a sequence that treat one or more water quality problems. Again, when considering water treatment, use your lab test results as a guide and make sure the technology you are considering is designed to treat the problematic substances in your water.

My most recent obsession
Size: 3 Ounce (Pack of 4), Size: 3 Ounce (Pack of 4)
The best canned oysters I've had yet! Theses oysters taste very fresh and clean, no crunchy bits like the cheaper ones. They're perfectly soft and melt in your mouth. I like eating them straight out the can but I also like mixing them with mayo, some of the olive oil from the can, some crushed pepper and eating them on baguette slices. These are so good my brother has started stealing them from me. I'm gonna have to start hiding them.

Great Tinned Oysters from South Korea No seed oils !!
Size: 3 Ounce (Pack of 12)
Great canned smoked oysters- the smoke flavor was very strong in the can I used to make faux Oysters Rockefeller. Next time I will drain them a little more and add a few drops of lemon or vinegar. There were 9 plump oysters carefully packed in olive oil in the first can opened and it made a great meal. I opened another can the next day and drained it well. adding a few drops of vinegar The second can's flavor was balanced, smokey and delicious. Online there are many recipe ideas incorporating these delicious oysters. These appear to be a superior quality of canned seafood from South Korean fisheries and in my opinion there are none of the known food safety issues which are my concern when dealing with the admittedly less expensive (half the price) brands from the other asian fisheries. I consider these a good value due to advertised no industrial seed oils and the quality of the oysters. 4 stars due to the cost/ 5 stars for taste
