1. CARBON CATALYTIC
Catalytic carbon is a kind of activated carbon that has been modified to improve its catalytic capabilities. It is mainly used to remove chloramine from water, and is a solvent that is increasingly being used to filter water at water treatment facilities. Chloramine has increased in popularity due to its ability to keep bacteria at bay as water flows into pipes. However, unlike chlorine, chloramine is exceedingly difficult to extract from water until it enters the tap. Although activated carbon extracts a limited amount of chloramine from drinking water, catalytic carbon removes the vast majority of chloramine.
2. KDF stands for Knowledge Development Fund (KINETIC DEGRADATION FLUXION)
This media, which is mainly composed of copper and zinc particles, is used to decrease the amounts of water-soluble heavy metals such as chlorine, iron, and hydrogen sulphide. In addition, it controls size, bacteria, and algae in the water. It is highly effective at removing chlorine, but not as effective as carbon/GAC at removing chloramine. Alternatively, since this media is less expensive to operate, lasts longer, and operates better at higher temperatures than carbon, it performs well in colder water. The use of KDF media upstream of a carbon filter works very well. The KDF extends the life of the carbon, and the carbon works well reducing the chloramine and THM levels.
3. ACTIVATED CARBON
By far the most common medium is activated carbon. When organic material with a high carbon content (such as wood, coal, or coconut shells) is heated in such a way that it does not burn, char is formed. The char is then refined to produce a porous substance that binds to particular toxins and impurities, drawing them out of the water circulating through the system. It’s worth noting once again that not all activated carbon is made from the same base content. Although some activated carbon is made from coal, it can also be made from coconut shells, and has a much lower environmental effect.
This is a bit of a catch-all. Mixed media can be almost anything and, as the name implies, is a combi4nation of various mediums used to extract additional impurities and contaminants. These media may include gravel for sediment removal, resin for tannin removal, and catalytic carbon for chloramine reduction.
5. MEMBRANE With REVERSE OSMOSIS
The reverse osmosis method is a very common filtration device that eliminates a significant percentage of impurities from water, including those that are hazardous, such as asbestos and hexavalent chromium. It acts by forcing water through a semipermeable membrane, which enables water molecules to pass through while trapping water-soluble contaminants such as heavy metals, organics, bacteria, and pyrogens.
6, ACTIVATED ALUMINUM
Enabled aluminium, which is commonly present in ion exchange units, destroys magnesium and calcium, two minerals that cause “hot water.” If enough time is spent in contact with this media form, it may also eliminate fluoride and arsenic. It will flush out radium and barium depending on the form of activated aluminium used. Activated aluminium is also used as a resin.
7. LIGHT IN ULTRAVIOLET (UV FILTRATION)
Water is injected into a cavity containing an ultraviolet light bulb. The ultraviolet rays emitted are fine-tuned to target microbes most effectively. These rays pierce the cell walls, allowing pollutants and their DNA to be destroyed, stopping them from reproducing. This leaves potentially toxic pollutants, such as E.Coli and giardia, entirely harmless.
UV filtration can be seen at all stages of water treatment. It is not only considered to be an important method of eliminating the risks of bacteria and viruses, but it also does so without contaminating the water with harsh chemicals.
8. DIOXIDE OF MANGANESE
Manganese dioxide is a key ingredient in a few different forms of media. Iron, manganese, and hydrogen sulphide are reduced in water by these media. Although iron is beneficial to health, it also serves as a secondary contaminant in water, causing issues when producing tea or coffee or cooking vegetables. Excess iron in drinking water can cause reddish-brown stains on dishes and clothing.
