Coconut Activated Carbon is the Best for Odor & Air Purification

April 26, 2021April 28, 2021 micbacindia-admin

Why activated carbon is used for purifying air? Well, it is simply because 1gm activated carbon offers 3000 sqmeters for capturing odorous air molecules. This surface area is equal to a football stadium. Are you confused? When oxygen and charcoalare treated together, millions of tiny pores open between carbon atoms. The activated carbon thus gets enhanced adsorption capability. With this quality, active carbon is extensively used in air and water purification.

The Process of Activation

Activation is the process of making carbon porous so that its 75% volume has empty space. Thus, carbon’s density gets reduced. This is done by passing steam to red hot charcoal. Activation can be done with the help of chemicals also, but steam generates greater porosity than chemical activation. That is why, activated carbon is being used as adsorbent. No material can develop such huge empty space by a simple process.

Different Sources of Activated Carbon

There are three grades of activated carbon according to their porosity –

Coconut
Coal
Wood

Coconut carbon is produced from coconut shells by the process of activation. Coconuts have micro pores meaning their pore diameter is less than 2nm. Coal has mesopores implying their pore diameter is between 2 to 50nm and wood has pore diameter of over 50nm. Application of the different grades of carbons are also different.

Applications of Different Activated Carbon

Molecules having micro diameter are in gaseous form as attractive force of the molecules is much less, it cannot withhold them from escaping to gaseous form. Since coconut carbon has micro pore diameter, coconut activated carbon is the best for capturing molecules and holding them firmly without allowing them to escape.

Coal carbon has meso pore diameter and therefore, coal based activated carbon is best for absorbing vapors of low molecular liquids. That is why, it has wide usage in water purification.

Wood carbon have macro pore diameter and are suitable for absorbing bigger molecules like dyes. So, wood based activated carbon are used for decoloring of varied liquids.

Thus, when it is about controlling odor and air purification, coconut based activated carbon is the best. For any practical purpose, activated coconut carbon should be used as filter for contaminated air. Now, to increase the adsorption capacity, chemicals are mixed with carbon because carbon is inert to chemicals. In other words, coconut carbon is the best material for odor controlling system, air purification, removal of toxic gas and disinfection management.

Explore The Benefits And The Use of Granular Activated Carbon Filter

People are widely looking for the filtration media. Staying healthy is an important fact which maximum people are having a concern. There are several forms of filtration techniques. One of the most popular forms is with the use of activated carbon. You can get a natural filtration technique when the coconuts shell is burnt. Also, this form of the filtration technique is affordable and has a great sustainability.

Sometimes excessive chlorine in the water may disrupt its actual taste. Activated carbon is a wonderful form of the filtration element through which you will be able to get the best result. Other types of carbon filtration technique are used with the help of the carbon form named as the granular activated carbon. We will get its uses and benefits in this blog.

Benefits of Granular Activated Carbon Filter

There are several benefits and uses of the granular activated carbon. Let us explore the benefits and uses of the carbon and its forms.

Removal of Contamination

Who wishes to intake the contaminated water; in fact no one would like it practically? The water gets contaminated due to variety of pollutants and the waste particle that is thrown inside the big water bodies. The best way of removing such contamination is the use of carbon. The granular activated carbon will remove the volatile organic compound, chlorine and other by products available in the environment.

Durability

It is true that carbon has the larger surface area. As a result, it will absorb more contaminants from the water surface. But there are several carbons which can become harmful to human beings if it is used for more than 3-4 months. The granular activated carbon is quite durable and you can easily use its filter for a long time. Also, if you can infuse it with any type of bacteria inhibiting agent or silver metal, the extent of durability will increase.

Pressure Drops

Usually when the filter media is put in the way of water, there is a good chance that there is a reduction of the water pressure. Carbon is also one of the elements which can cause the drop of water pressure. But, in the granular form of carbon the blocks of carbon are loose. As a result, it allows the water to pass appropriately. Thus, there is no issue of pressure dropping.

Application of Granular Activated Carbon

The granular activated carbon filter is used as a stand-alone filter in the under sink, counter tops, etc
It is also used in the in-line filters, due to which the Chorine will be removed and the taste of the tap water will be boosted.
The carbon block is highly effective in the reverse osmosis system.
UV purification system is another important benefit of the Granular activated carbon filter
Granular Activated carbon is mostly used in the fridge filter, shower filter etc.

After looking at the above benefits and the uses of the Granular activated carbon, you must be clear about its features. You can also try it out for your industry or domestic purpose now.

What Role Does Granular Activated Carbon Play In Water Treatment?

Granulated activated carbon, abbreviated as GAC, is often used for the purpose of water filtration these days. It may be used solitary or along with some other technologies for the purpose of disinfection or for some other end, to get the kind of water quality that is desired. For instance, it may be used along with ozone in the Biological Activated Carbon Process, which is a special type of treatment. This kind of carbon may be reactivated via thermal oxidation – that lets it be used many times.

High Adsorptive Capacity

A hybrid mixture of various kinds of graphite platelets, connected with each other by the help of non-graphite carbon bonding, Granular activated carbon (GAC) is known for its amazing adsorptive capacity. This makes it perfect for removing various kinds of contaminants from gases, liquids, air and water. This is an eco-friendly product which may be reactivated via thermal oxidation. It may be used for many times even for the same purpose.

Granular activated carbon particles are generally bigger in size as compared to the regular sand media, performance and design considerations are important for deriving the advantages of this kind of carbon in a surface water plant.

Powerful Physical Filtration

Granular activated carbon (GAC) is used in water treatment plants, proving to be a robust physical filtration medium. It is also beneficial in protecting the quality of water, through the adsorption of chemical contaminants, odor compounds, taste etc.

Surface water filtration, to use for consumption, is commonly used since water treatment started. The earliest designs used gravel and sand combinations, which helps reduce water turbidity. Regular practices of treatment use influent raw water chemical coagulation, chlorine treatment, filtration via gravel / sand media and to distribute to customers.

Organic Compound Removal

Granulated activated carbon, other than removing odor compounds and taste, also helps get rid of various other types of organic compounds. For instance, during groundwater treatment, contaminants that are man-made can be removed often with efficiency with the aid of GAC. It is highly important for groundwater as well as surface water, and is very important when you consider what the health benefits of pesticides and other specific compounds are. GAC’s particle size is described generally with the help of the mesh size. It ensures effective filtration rates and happens to be the choice of filtration of water that is supplied by the municipal lines. With a move towards bigger mesh size, GAC products of an even larger size – such as 8×16 and 8×20, have been developed. In direct filtration plants, these have turned out to be extremely effectual mediums. This is due to the fact that these allow higher filtration rates and deeper beds, along with acceptable head loss.
