Whole House Multi Media Water Filter Systems

KDF 85 Media removes or reduces iron hydrogen sulfide from well, municipal or other water supplies.

Also Controls Scale, Bacteria and Algae.

The TWPROWH2 KDF 85 Iron/Hydrogen Sulfide reduction filter contains a combination of KDF 85 media and coconut shell activated carbon (GAC)

KDF 85 effectively reduces dissolved iron and hydrogen sulfide odor. Protecting your plumbing system including toilets, bath tubs, showers and appliances such as clothes washers and dish washers from unsightly staining and odor.

The GAC activated carbon removes organic contaminants to substantially improve water clarity, taste and odor. It does not add any harmful chemicals to water making it safe for drinking water applications.

1.5 Cu Ft of Granular Activated Carbon

Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent know to man. 1 pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. The most common carbon types used in water filtration are bituminous, wood and coconut shell carbon. While coconut shell carbon typically costs 20% more then the others, it is generally regarded as the most effective of the three. All our activated carbon filters use coconut shell carbon. These are two principal mechanisms by which activated carbon removes contaminants from water; absorption and catalytic reduction, a process involving the attraction of negatively charged contaminants ions to the positively charged activated carbon. Organic compounds are removed by absorption and residual disinfectants such as chlorine and chloramines are removed by catalytic reduction. Activated carbon filtration is very common in a number of home water treatment systems. It can be used as a stand alone filter to reduce or eliminate bad tastes and odors, chlorine and many organic contaminants in municipal (pre treated or chlorinated) water supplies to produce a significantly improved drinking water. It is also very commonly used as a pretreatment as part of a reverse osmosis system to reduce many organic contaminants, chlorine and other items that could foul the reverse osmosis membrane. Carbon block filters are commonly used to remove cysts such as giardia and cryptosporidium. Activated carbon filters removes/reduces many volatile organic chemicals (VOC), pesticides and herbicides, as well as chlorine, benzene, trihalomethane (THM) compounds, radon, solvents and hundreds of other man-made chemicals found in tap water.

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.

This system 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.
