A wide range of industrial water filters are available from Netsol Water, and they may be customised to meet the demands and requirements of any particular project. In addition, we provide top-notch RO plants and activated carbon filters, which can be used for any tertiary water treatment or water purification applications.
Let’s look at various applications of activated carbon.
What are the Various applications of activated carbon?
Activated carbon has a wide range of applications since it can adsorb organic substances, with a certain molecular weight on its surface.
The following are some of the most typical uses for activated carbon:
1. Retain and eliminate impurities that give drinking water its colour, odour, and flavour
Because of its surface, activated carbon is able to efficiently absorb the organic substances that give water its colour, flavour, and aroma. First, a steam-assisted activation is used to increase the carbon's surface area thermally, so that it can achieve extremely high temperatures.
After that, the surface area is increased to absorb flavours and scents from the water. Through the pores, an organic substance emits an unwelcome odour, which the activated carbon absorbs.
2. Degradation of oxidants like chlorine and ozone in drinking water
Reduction reactions occur when chlorine and other oxidants come into contact with activated carbon, converting HOCl or OCl- to chloride ions (Cl–).
3. The decaffeination of coffee
Activated carbon is used to decaffeinate coffee in an aqueous extract. To adsorb ethyl cellulose, activated charcoal is first added to a solution of the substance. Once the ethylcellulose-containing activated carbon has through a drying process, and is completely dry, aqueous coffee extract is then fed through it.
The activated carbon is ready for reuse in the same application after the aqueous extract, containing the caffeine is absorbed by the ethyl cellulose that is adsorbed by it. The carbon is then desorbed from the ethyl cellulose for use in other goods.
4. Sugar (refined sugar, honey, candies, etc.) discoloration
Sugarcane and other types of honey are discoloured in a liquid at a specific temperature, to lessen their viscosity. Darker syrups work best with soft wood chemically activated carbons. The pH of the activated carbon must be brought closer to neutral during this procedure.
5. The discoloration of alcohol, juice, and vinegar
The best activated carbon for this application is powdered wood because it has pores, which are the right size to adsorb colour molecules. It is applied directly to the liquid that needs to be coloured, while being constantly stirred until the desired colour is achieved; however, each liquid has a specific amount of contact time.
6. Distilled drinks are purified to remove some unfavourable chemicals, from their organoleptic profiles
Change the profiles, adjust the organoleptic properties, and get rid of any compounds that don't belong in a distillate. By using the proper activated carbon from the variety of raw materials and granulometries, it can therefore be enhanced or corrected.
7. Industrial procedures that treat water
The removal of organic pollutants from drinking water or surface waters, with activated carbon, is the most popular application for the material worldwide.
8. Wastewater treatment
The best activated carbon for this process is made of minerals. It can almost entirely eradicate the molecules of tertiary process water from wastewater, where it is only necessary to lower complicated colour and odour molecules.
9. Air and industrial gas purification
Similar to how organic contaminants in the water are held or adsorb on activated carbon, so are gases that flow through it. To prevent pressure dips, it typically utilizes activated carbon made from coconut shells, because it is a micro-pore material with a larger granulometries than that used in water treatment. Additionally, chemically altered activated carbons are employed to adsorb substances.
10. Cartridge respirators
Both the respirator and the activated carbon must meet certain requirements, in order to provide respiratory protection. The application is almost identical to that in air treatment, with the exception that in this case, the carbon must be specifically chosen to act more quickly, because respiratory protection is for human use.
11. Removing odours from closed spaces like kitchens, storage facilities, refrigerators, etc.
Odours brought on by food are naturally occurring. Because of this, activated carbon works very well to eliminate unpleasant odours. Refrigerator is the most direct application, but this can also be used on a larger industrial scale in cellars or cold rooms.
12. Cleansing compressed air
It is required to use a pump to fill a tank with compressed air or oxygen, but this can occasionally release traces of oil or other contaminants. To ensure that the air is technically oil-free, activated carbon adsorption filters are utilized, which efficiently minimise vapours originating from petroleum.
13. Medical care for severe poisonings
The employment of these technologies in hospital emergency rooms is one of the most fascinating. It is fairly usual for organic materials to cause poisoning. In an aqueous suspension, activated carbon is created and administered orally or by nasogastric tube.
After purifying the blood in the intestine, where it adsorbs the toxin that circulates in our bodies from the blood, which passes through the intestinal wall, activated carbon reaches the stomach and intestines. It then adsorbs the toxin that is located in these organs.
14. Activated charcoal dressings infused with silver are used to treat ulcers, burns, and wounds
The dressings used in medical paddles as a second application are manufactured, with extremely tight fibres to keep carbon from escaping the dressing. The usage of a micropore activated carbon impregnated with metallic silver serves two purposes:
First, it absorbs organic debris produced by wounds or skin sores and second, it kills germs by acting as a bacteriostatic agent and that it is not a hazardous substance for the body.
15. Recovery of valuable metals such as gold, silver, and others
The aforementioned metals can be retained by micropore activated carbon. According to the hydraulics of your operation, the proper size can provide adsorption kinetics that performs better than others.
In order to endure acid elution, washing procedures at various temperatures, and thermal reactivation, the physical characteristics also need to have a specified hardness. It is suitable for use in pulp coal (CIP) and leach coal (CIL) type procedures, for gold or silver heap leaching recovery.
