Whole House Water Filter System 1 CU FT Catalytic Carbon with Manual Backwash Valve. Whole-House Filter or Point of Entry. A whole-house filter is installed at a point on the homes water supply plumbing that will result in treatment of all water that travels to any faucet or fixture in the home.
Many water utilities across the U. Are transitioning to chloramine for disinfection as an alternative to chlorine. This change is in response to stricter U.
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 carbons 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.
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 educ-tor 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 backwash 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. This unit includes the following. 9"x 48" FRP Mineral Tank (Color Varies). Catalytic Carbon 1 CU FT.
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 traina 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. Manual Valve: How they work: The Manual valve. It has very few moving parts and easy to use. When you need to backwash a filter, you put it into the backwash cycle for 10 minutes, followed by a rinse for 3 minutes and then back to the service mode.
That is all there is to it. Once a week schedule for backwash is generally sufficient. For a more economical product and ease of use, we recommend you get this rather than opting for unit that does not backwash, read the section on the benefits of backwash. Benefits and Importance of a Backwash Cycle: As the filter operates in service mode, it accumulates particles in the filter bed. Also since water's nature is to follow the path of least resistance, after time it begins to create channels through the medium.
As channels or holes in the media bed form, water begins to flow around rather than through the medium. This process is called "channeling" and it reduces the effectiveness of the filter considerably. The backwash is accomplished by sending the water down the riser tube from which it enters the filter tank at the bottom. The force of the water is such that it actually lifts the media bed, swirling and tossing the granular medium. The water leaves the filter's drain line.
The purpose of this rinse is to rinse and settle the bed an prepare it for return to service mode. A regular backwash schedule maintains the efficiency of the filter, as well as providing cleaner water.
