How does Granular Activated Carbon help Filtering Water Contaminants?

Granular activated carbon manufacturer

Granulated activated carbon is a typical filter material utilized in water filtration frameworks. It’s a demonstrated method to eliminate certain natural synthetic compounds from water. GAC filters are also compelling at eliminating pollutants that give an offensive smell or taste to drinking water, similar to hydrogen sulfide or chlorine.

What Is A Granulated Active Carbon Filter?

Granular Activated Carbon is produced using natural materials which have high carbon content like coconut shells or coal. The material is warmed in a without oxygen chamber to enact the outside of the carbon, which is the reason these filters are regularly alluded to as “charcoal” filters. The activated carbon better eliminates certain synthetics that are dissolved in water by catching the synthetic compounds in the carbon.

Like all water filtration frameworks, appropriate establishment and ordinary support is critical to keep up the most noteworthy capacity. With GAC filters, the carbon gets immersed and not, at this point successful after a specific length of administration. How regularly filters should be changed is also controlled by the degree of toxins present and measure of water utilized. Some filters keep going for quite a long while if water use and pollutants levels are low. If levels and use are higher, more successive filter changes are encouraged.

Sorts of GAC or Granulated Active Carbon Filtration Systems

MARK OF ENTRY FILTRATION

There are two essential sorts of water filtration frameworks accessible to property holders and GAC filters are utilized in both. An entire house or “Mark of Entry” framework takes water from your well and treats it before it enters your home’s pipes framework. Commonly a POE framework treats the entirety of the water outlets, fixtures, clothes washer, and dishwasher, but rejects open air spigots to help delay the life of the GAC filter. POE frameworks as a rule comprise of 2 filtering chambers that treat the water in succession. The subsequent filter intended to additional clean the water of impurities that may have gone through the first.

PLACE OF USE FILTRATION

The second kind of framework is designated “Mark of Use.” Point of utilization frameworks are introduced not long before the fixture where individuals get their water. One regular framework comprises of a free fixture solely for treated water normally situated close to the kitchen spigot for instance. Another illustration of POU filters that utilization GAC are the pitcher filters normally sold in supermarkets. Granular Activated Carbon filters are also remembered for some fridges that apportion drinking water and ice. If you’re thinking about adding a water treatment framework in your home and don’t know if a GAC situation is appropriate for you, contact a qualified well water project worker. They can give you the entirety of your alternatives, alongside the establishment costs, and can assist you with getting your water tried to figure out what sort of framework is the awesome your family. A water treatment framework is a shrewd interest in the health of your friends and family!

Get an Insight about Activated Carbon and Its Utility

Coconut Shell Granular Activated Carbon

Active carbon, popularly known as activated carbon or activated charcoal, is processed carbon that helps in adsorbing organics, odors, tannins and toxins from water. Different materials are used for producing activated charcoal of which coal is common. This processed carbon is available in diverse size, shape and form and also has their own disadvantages and advantages.

VARIETIES OF ACTIVATED CARBON

  • Lignite

This active carbon is produced from peat and wood and is light and soft. It has large pores which make it suitable for adsorption of large organic molecules and other types of contaminants. Lignite is highly effective but, using it is a little difficult because, being a soft material,it takes longer time to rinse.

  • Coconut

This activated charcoal is made from coconut tree and has small pores. It is dense as well as hard, and therefore, it is ideal for removal of high or small energy organic molecules.

  • Bituminous

This activated carbon is made from coal and has medium pores. It is soft but dense and comes with diverse types of pore sizes making it suitable for removing contaminants of different shapes and sizes.Bituminous is hard, easily usable and affordableand does not create much dust. This processed carbon is commonly used for aquariums.

PROCESS OF CREATING GRANULAR ACTIVE CARBON

  • Pulverization

In this stage, the base product coal is crushed into fine powder.

  • Agglomeration

In this, the powdered carbon is reformed, under pressure, into briquettes. 

  • Crushing

Then the briquettes are broken to get the required particle size.

  • Baking

They are then baked at a temperature as high as 8000F for removing VOCs.

  • Activation

The carbon is then thermally activated by exposing it to a temperature of around 19000F. Activation takes place in a controlled atmosphere by using salts, acid, stem or oxygen.

  • Screened

The final product, active carbon, is separated according to their use, shape and size.

USE OF ACTIVATED CHARCOAL IN AQUARIUM

Activated carbon is highly effective in improving quality of water by removing several items like contaminates, organics, colors, odors and toxins. Bu the use of carbon the water becomes pure. However, there are certain drawbacks of using active carbon on aquarium. Firstly, carbon adsorbs certain beneficial elements like medications, amino acids and iodine, together with impurities. Again, carbon can release various organics and phosphate back in water, especially when it is not acid washed. Despite the disadvantages, activated charcoal or carbon has wide utility in water purification.

Types of Natural Resources Activated Carbon is Obtained From

activated carbon manufacturers in india

Activated carbon is a very absorptive, highly porous and carbonaceous medium which has a complex structure and is mainly made up of carbon atoms. In activated carbons, there is a network of pores that are channels developed in a firm structure of carbon atoms in disorganized layers. These are joined with each other by chemical bonds that are stacked in an irregular fashion, and can develop a very porous structure of crevices, cracks, nooks and crannies between the layers of carbon. Know about the various kinds of natural resources that activated carbon can be obtained from.

Wood

A non-graphite form of carbon, Activated carbon can be produced when any carbonaceous material gets activated – be it paddy husk, lignite, coal, sawdust, wood chips, bamboo or coconut shells. Activated carbon that is obtained from wood is a type of carbon that is processed in order to be riddled with low-volume and small sized pores which increase the surface area that is present for chemical reactions or for adsorption.

Coconut Shell

An amorphous from of carbon, Activated carbon has been treated for the production of well-developed pore structure that leads to an extremely large internal surface area. Activated carbon from coconut shells is able to absorb dispersed or dissolved materials from liquid phase and vapors and gases from a gaseous phase. Activated carbon may be used also for purifying water and air, electrode production and sugar refining purposes.

Rice Husk and Saw Dust

Carbon is possibly the element that is distributed most widely in nature. Activated carbon that is obtained from rice husk is used for wide purposes. In India, there is major scope for activated carbon manufacturing from rice husk. It is used most often for purifying solutions, like cleaning up corn sugar, beet and crane solution as well as for removing odors and taste from water, pharmaceuticals, chemicals, alcoholic beverages, oils, animal fats, vegetable etc.

Bamboo

Activated carbon that is obtained from bamboo is micro crystalline in form, and happens to be a non-graphite type of carbon. In various industries, it is used extensively, and is found to absorb color or odor very well. Bamboo is one of the top raw materials that activated carbon is often sourced from, in countries like India. The activated carbon that is produced in this way is used in India in a wide range of industries and for various purposes – such as for the manufacturing of electro chemicals, synthetic rayons, pharmaceuticals, chemicals, sugar, glucose etc. It is used for water treatment and for the extraction of solvent and Vanaspati.
