Multi-Stage Filtration: KDF Filter

Pre-filters are used in multi-stage industrial filtration systems to increase the performance of the normally more expensive primary filter, which can save money if done correctly. Multi-stage filtration, also known as series filtration, can prolong the life of the primary filter, which is typically more expensive than the pre-filters that protect it.

In addition to lowering expenses, well-engineered series filtration can save maintenance hours spent servicing filtration systems and equipment.

Ace Water Coolers incorporates different filters to offer a premium quality multi-stage filtration for your water coolers and purifiers. In this article, we'll talk about the KDF Filter. It's one of the filters included in multi-stage filtration.

KDF FILTER

Some use KDF Process Media in a wide range of pretreatment, primary water treatment, and industrial treatment applications. They're commonly utilized instead of or in addition to granular activated carbon filters and carbon block and inline filters. KDF water filter medium extends the life of granular activated carbon (GAC) while preserving it from bacterial fouling.

Most people replace silver-impregnated systems with this water filtration media. KDF Process Media are not harmful. However, silver is. KDF Process Media does not need to register as a hazardous pesticide with the EPA. Silver costs more than KDF Process Media, by the way.

HOW IT WORKS

Water goes through a cartridge or tank before exiting your faucet or showerhead when using KDF filter media technologies. Water must travel through the redox media at some point before it can leave your pipes, whether you're using whole-house KDF filter media or dedicated shower or faucet filter systems.

Copper and zinc combine when water passes through KDF filter media to produce an electrochemical/redox reaction. Electrons in the filter medium trade places with pollutants in the water during this reaction. The KDF media then changes these pollutants to make them harmless. A redox reaction is the transfer of electrons.

Electrons between the different molecules swap as water travels through the copper-zinc granules in the KDF process media, resulting in innocuous components. The redox process, in the end, is founded on the notion of opposites at work.

Some contaminants link with the granules (e.g., heavy metals) like water and oxygen flow through the bed of granules. In contrast, others react to produce new elements in controlled levels that are innocuous if consumed.

KDF contains fungal, algae, bacterium, and virus inhibitory capabilities in addition to its pollutant reduction capabilities via the electrochemical method of oxidation-reduction, which has substantial consequences for the life span of these filters.

WATER FILTRATION

KDF has a variety of applications as a filter media in both household and industrial water filtration.

In household water treatment equipment, you can find KDF in point-of-entry filters and various point-of-use filters, such as under-sink filters, shower filters, and refrigerator filters.

KDF is utilized in manufacturing water filtration, restaurants, hospitals, and any other industry where toxins that KDF can eliminate are judged undesirable in water.

WHAT ARE THE BENEFITS OF USING KDF PROCESS MEDIA?

There are numerous good water filtration/purification systems and technologies on the market.

So, why should you use KDF Process Media? We can provide you with two compelling arguments. One, because KDF Process Media improves the performance, lengthen the life, reduce maintenance, and reduce the total cost of many carbon-based systems now on the market. Two: KDF Process Media aid in the control of germs by generating an environment that is lethal to some microbes while interfering with the capacity to operate of many others. In each case, using KDF Process Media leads to the complete eradication of some pollutants and significantly reducing others.

The Advantages of KDF Process Media

• Extend the life of granular activated carbon by a significant amount
• Reusable
• It effectively removes chlorine and heavy metals while controlling the microbes.
• There are four granular styles to choose from. Each meant to meet a distinct requirement.
• Carbons impregnated with silver outperform silver-impregnated carbons.
• No EPA registration is required, resulting in less red tape.

KDF GRANULE VARIATIONS

KDF copper/zinc media come in four different types: KDF-55, KDF-85, KDF-F Fine Mesh, and KDF-C Coarse Mesh. In terms of water treatment efficacy and what it decreases or removes, each granule variety of KDF is slightly different.

KDF-55

The KDF-55 granules intend to minimize chlorine accumulation in water systems electrochemically. KDF-55 can also convert heavy metals in water into innocuous compounds. You can find a KDF-55 filter in a whole-house system, a specific faucet filter, or a showerhead filter.

KDF-85

KDF-85 This sort of filter media is also good at removing bacteria, making it perfect for purifying well water and avoiding the growth of hazardous microbes. Because it controls scale, you can normally add a KDF-85 filter to a whole-house system or a water softener for added efficiency. You can use it independently as a filter.

KDF-F Fine Mesh

KDF-F fine mesh frequently goes with other filtration media, such as an activated carbon filter, to increase overall filtration efficiency and lengthen filter lifespan. Some use KDF-F filter grains in whole-house and specialty filter systems.

KDF-C Coarse Mesh

Finally, for eliminating chlorine and water-soluble heavy metals, KDF-C coarse mesh granules are an alternative. These filter media, like KDF-55, can be utilized in showerhead filters, faucet filters, and whole-home systems.

WHAT IT REMOVES FROM YOUR WATER

Free Chlorine

The chlorine you find in water is free, total chlorine, or mixed chlorine. Only free chlorine is responsible for removing germs in the water, and KDF removes oxidizing pollutants.

Free chlorine also has several unfavorable effects on hair, skin, eyes, and lungs. As a result, you want free chlorine eliminated from your water system.

Chlorine reacts with other pollutants in water is known as total or mixed chlorine. This chlorine has minimal to no sanitizing or oxidizing properties.

You can clear both free and total chlorine if your water filtration system includes KDF and carbon media.

KDF eliminates 99 percent of free chlorine, allowing activated carbon filters to remove organic pollutants more effectively.

Heavy Metals

The list of pollutants that KDF can remove thus far has proven outstanding; however, its ability to remove heavy metals such as nickel, chromium, lead, mercury, and other heavy metals is even more amazing.

It removes heavy metals by attaching them to the surface of the filter grains, which is how KDF works.

Iron

By converting soluble ferrous cations to insoluble ferric hydroxide, KDF can filter more than 90% of iron from your water supply. It strains the new by-product via the filter bed and back washed periodically to eliminate it.

Hydrogen Sulphide

Hydrogen sulfide is another pollutant that KDF may easily remove. KDF converts hydrogen sulfide to insoluble copper sulfide strained through the filter bed and released the same way iron.

Other Water Pollutants

KDF can also handle calcium carbonate and magnesium, in addition to these pollutants. Bacteria, algae, viruses, and fungi are all inhibited by KDF.

It is a significant benefit of KDF filters, as the incapacity of organic-based media to limit bacterial growth is generally the reason for their lower service life when compared to antibacterial filters.

PROS AND CONS OF USING KDF

KDF provides numerous advantages, including:

• Extends the life of carbon filters and improves their performance;
• It's 100 percent recyclable;
• It comes in a variety of granular styles for a more targeted filtration strategy;
• It's antibacterial, and it outperforms other antibacterial filters on the market.
• It also works well at greater water temps.

Here are some downsides of KDF water filters to be aware of:

• It doesn't remove organic chemicals like (pesticides, MTBEs, disinfection by-products, etc. Backwashing with hot water is required to remove insoluble pollutants.
• When used in conjunction with other water filter media, it maximizes the benefits of this technology.

ADVANTAGES OF KDF FILTER IN A MULTI-STAGE FILTRATION

KDF process media have a variety of advantages over conventional water filters, such as carbon filters, that make them the more desirable alternative.

Great for Hot Water

Activated carbon filters, for example, cannot be used with hot water. The heat could destroy the design of the filter surface, preventing it from trapping impurities properly. On the other hand, a KDF process media is harmless to use with hot water, making it an excellent choice for showerhead filters.

Inhibit Bacteria Growth

Because most filters don't have small enough pore sizes to trap pollutants so small, it's difficult to find a water filter that can stop bacteria, fungi, and algae from growing. This medium is an excellent water treatment for bacteria and decreases or removes other undesirable microorganisms like algae. It uses a chemical process to treat water rather than a filter cartridge.

Works Well With Other Filters

Even the most effective water filters have their limitations. A KDF filter can be used with other filters, such as granular activated carbon (GAC) and activated carbon block filters, which can remove more contaminants and increase the filter's life. For the greatest results, utilize the KDF process medium with a carbon filter to eliminate chlorine, heavy metals, bacteria, and iron.

Budget-Friendly

When compared to other filter types, KDF process media are quite inexpensive to purchase. One of the biggest advantages of KDF media is that it does not require costly maintenance, such as regular filter cartridge changes, so you won't have to budget for it like you would with other media.

Flexible

There are four main varieties of KDF process media. Each of the variants uses a slightly different procedure to minimize or eliminate various sorts of dangerous contaminants. It filters heavy metals such as lead, mercury, and others, chlorine, bacteria, and algae, chromium, and other dissolved solids. This sort of filtration can cause a redox reaction or oxygen reduction (redox), which can remove sulfur and iron, two pollutants that many filers have trouble with. KDF process media, unlike granular activated carbon filters and comparable water filter treatments, can be modified for diverse needs.

Recyclable

Most KDF process media consist of totally recyclable components with no chemical additives. Because KDF filters are recyclable, they can be recycled and replaced when they no longer filter your water adequately. It doesn't leave a negative impact on the environment.
