The Biggest PROBLEMS With Granular Activated Carbon Filtration

The Biggest Problems With Granular Activated Carbon Filtration

GAC (Granular Activated Carbon), a water-cleaning material, effectively captures germs and chemicals.

Red CrossHowever, it has limitations in dealing with heavy metals and minerals in water.

Red CrossGAC is highly effective against organic compounds and some chemicals, but its efficiency in addressing minerals and metals may be insufficient for comprehensive water purification.

Red CrossAdditionally, the effectiveness of GAC can diminish over time, requiring regular filter cartridge replacements to maintain optimal filtration performance.

What is Granular Activated Carbon?

All forms of GAC (Granular Activated Carbon) comes from organic materials with a high natural carbon content. For instance wood or coal that go under a lot of heat pressure with little or no oxygen.

This removes water and contaminants without allowing the material to burn. The result is char or charcoal.

Meanwhile activated carbon itself comes from a variety of chemical and physical processing techniques to greatly increase its surface area and create a network of submicroscopic pores.

The final product, known as activated carbon, has a remarkable ability to attract and bind a variety of compounds.

Activated carbon plus other chemicals can improve its ability to bind to specific compounds.

This basically means that GAC is very good at attracting all the impurities away from your water. This leaves you with fresh pure, clean drinking water.

Granular activated carbon is a highly porous adsorption material produced by heating organic material, such as coal, wood and coconut shell.Pelican Filtered Undersink

This is done in the absence of air or oxygen. The resulting products are then crushed to form granules.

Activated carbon has a positive charge and therefore, is capable of eliminating negative ions from water.

However, you should also note that it is not effective in the removal of heavy metals.

How Does Granular Activated Carbon Work

The process works through the so-called adsorption process.

After absorption, the compounds are evenly distributed throughout the absorbent product, like a sponge that absorbs water. However, after adsorption, the compounds only bind to the molecules on the surface and produce a film.

AquaTruOf course, carbon molecules are attractive. That is, actively seek other molecules to connect.

The immense surface and the very porous nature of the activated carbon allow the adsorbed compounds to penetrate completely into the material and find all available junctions.

There are also chemical reactions that convert some offensive compounds into less disturbing variations. Although activated carbon is not effective against all compounds, it has the ability to combine with compounds in all three phases: liquid, solid and gaseous.

Granular Activated Carbon vs Powdered Activated Carbon

This is a complicated question. But, in simple terms, the biggest difference is in the structure.

Powdered activated carbon is in a powder form. While granular activated carbon is often slightly larger grains.

Granular Activated Carbon Filter Design

Granular activated carbon are useful for a variety of applications. Depending on the size you choose and whether you use GAC (Granular Activated Carbon) or EAC (Extruded Activated Carbon).

AquaTru FiltersBoth forms have a high diffusion rate and are particularly good at adsorbing vapors and gases.

GAC is useful in water treatment and deodorization applications. While EAC is ideal for gaseous phase applications due to its low dust content.

Granulated activated carbon can eliminate most, if not all, organic compounds.

However, it is a poor choice for most inorganic compounds, which are normally in ionized form in water, creating strong bonds that are difficult to break granular activated carbon.

Pelican RO Filtered UndersinkSeveral impregnations are available to improve the ability of the GAC or EAC to adsorb these compounds.

Choosing the correct form of activated carbon can be complex.

Even if you have limited your preference for GAC or EAC. It is important to choose the size that best suits the connections you want to eliminate.

Hiring a professional plumber is the best way to make sure you buy the right product for you.

Granular Activated Carbon Suppliers

Dedicated granular activated carbon suppliers are pretty thin on the ground. And by that I mean companies that only supply this product.

However, you can try businesses that specialize in water filter products like Aquasana.

Or though online stores like Amazon and eBay.
