WHOLE HOUSE WELL WATER FILTER SYSTEM - 2 CU FT CATALYTIC CARBON - KDF 85 MEDIA GUARD -FLECK 5600SXT DIGITAL FILTER BACKWASH VALVE. 1" BYPASS
1. Whole-House Filter or Point of Entry:
A whole-house filter is installed at a point on the home’s water supply plumbing that will result in treatment of all water that travels to any faucet or fixture in the home.
A whole-house filter system treats all water traveling to any faucet or fixture in the home. It removes the chemical before it can be ingested, breathed in, or absorbed by the skin during washing or bathing.
Catalytic Carbon high activity granular activated carbon manufactured by steam activation of select coconut shell charcoal. The Catalytic activity of this activated carbon makes it highly effective for the removal of chloramines from potable water. Its large micropore volume makes it particularly well suited for the removal low molecular weight organic compounds and their chlorinate by-products such as chloroform and other trihalomethanes (THMs). An important feature of this material is its superior mechanical hardness and extensive dedusting during its manufacture ensures an exceptionally clean activated carbon product.

One of the key characteristics of activated carbon is not only the high surface area available relative to their mass, but also the ability to act as a substrate for other materials. Internal surface area in the range of 850-2000m2/g allows the concentrated loading of highly specialized reagents (for example platinum and rhodium for hydrogenation processes) to the carbon surface that can be used in synthesis and catalysis applications across a range of industries. Activated carbons are carefully engineered to have the correct physical properties to optimize their use in this duty, manufactured from coconut shell, coal or wood bases.
Many water utilities across the U.S. are transitioning to chloramine for disinfection as an alternative to chlorine. This change is in response to stricter U.S. Environmental Protection Agency regulations on disinfection byproducts (DBPs), which are created when chlorine reacts with organics in water. Chloramine, a combination of chlorine and ammonia, is more stable and does not create DPBs.
Removing chloramine at the point of use, however, is more difficult than removing chlorine. Standard granular activated carbon (GAC) and carbon gac products have limited capacity for chloramine reduction. Products known as “catalytic” or “surface-modified” activated carbon can provide a solution.
In general, the catalytic properties of carbon are measured by the rate at which carbon decomposes hydrogen peroxide. The resulting peroxide number, measured in minutes, estimates the carbon’s utility in any catalytic application, including chloramine reduction. Based on the comparative results obtained for different mesh size commercial carbons, the efficiency of chloramine reduction is discussed in the terms of peroxide decomposition capacity and further extended to the total life (volume) claims for corresponding GAC carbon.
Whole House Water Filter With consistently superior KDF85 medium is a economical pretreatment unit which is able to turn your water filter in to a high performance water filtration system by by reducing chlorine, heavy metals and inhibits bacteria growth from water without adding chemicals. KDF 55 & KDF 85 process media can remove up to 99% of water soluble lead, mercury, nickel, chromium, chlorine and Hydrogen Sulfide and other dissolved metals. All KDF process media forms are effective in controlling the build up of bacteria, algae, fungi and scale, make the ideal for use in GAC beds, ion exchange resins, carbon block filters and inline carbon filters.
Wherever KDF Media are used, they can eliminate the need for sometimes harmful chemical treatments. KDF Fluid Treatment is a technological leader in the fluid treatment industry. KDF process media are high purity copper-zinc formulations used in pre treatment, primary treatment and waste water applications. KDF media supplement or replace existing technologies to extend system life, reduce heavy metals, microorganisms, scale, lower total cost and decrease maintenance.
KDF process media are recyclable and contain no chemical additives. Homes, hospitals, restaurants,municipal water treatment facilities rely on KDF process media to safely reduce or remove chlorine, iron, hydrogen sulfide, heavy metals and bacteria from water.
Media-Guard KDF85 is for well water and removes/reduces soluble iron, hydrogen sulfate, chlorine, heavy metals from water and bacteriostatic. Good tasting water throughout the whole house. No maintenance needed on media-guard system.
Chemistry of Iron Oxidation:
A mineral found in soil, iron normally exists in an insoluble oxide form, namely ferric oxide. If acidic ~ or carbon dioxide ~ containing water passes through the soil, the insoluble ferric oxide is reduced to the very soluble ferrous form. When water is pumped from the ground, oxygen from air enters the water and is available for reaction with the ferrous iron. In the presence of oxygen the ferrous form is eventually oxidized to the insoluble ferric form, resulting in familiar red deposits that stain sinks and clothes.
In iron removal processes, the insoluble ferric hydroxide comes out of solution and is separated from the water by either filtration or settling. Catalytic carbon accelerates the reaction rate of ferrous to ferric iron dramatically, completely removing the in the relatively short time the water is in contact with the carbon
Under normal conditions, the reaction rate of ferrous to ferric iron is fairly slow, even when excess oxygen is present. This slow reaction rate necessitates the use of large retention tank and sedimentation tanks to allow time for precipitation to occur. A separate filtration step is then required to remove the remaining particulate.
In treating iron-laden water, the catalytic properties of the form of granular activated carbon perform quite differently from standard activated carbon. The catalytic properties greatly accelerates the reaction time of iron to an insoluble form. By oxidizing iron from a soluble to less soluble state, catalytic carbon serves to simplify the removal.
The resultant increase in reaction rate that occurs by using catalytic carbon allows smaller pieces of equipment to be used. As with all oxidation techniques, oxygen is required ~ but a simple eductor or air injection pump is all that is required. As the reaction occurs, the precipitate is collected on the surface of the carbon, and a secondary filter is not required. Periodic backwashing is performed to remove this iron floc and return the carbon to a usable state.
Another benefit of the catalytic carbon is its proven performance in removing hydrogen sulfide (H2S) from water. Many iron-containing waters also contain H2S and same bed of catalytic carbon can be used to remove both.
Similarly, the unique reactive nature of the internal surface of activated carbon means that there is an inherent ability for the promotion of reactions between gases and liquids that would either proceed too slowly or generate uneconomic yields of final product. This is achieved without the need for the addition of a chemical reagent to the activated carbon and often true catalysis proceeds, without degradation of the surface or adsorbent.

**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.
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:
- The substances you want to treat
- 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.
