Which one should I use, ozone generator or carbon filter?

Granular Activated Carbon

Carbon is a versatile purification technology used in other filtration processes, such as water filtration, which removes a variety of contaminants from a given environment. This filtration technology is widely used for its inherent ability to filter and remove contaminants from the environment as well as odors.

The common use of carbon in personal life is more prevalent than most people realize, and the list may surprise you when it comes to the different products that contain carbon in their structure. Carbon is used in soap, toothpaste and other personal products that people use almost every day. When using carbon in an air purifier or air filter, is it the best and most effective option for ensuring safe indoor air?

 

In this article, we will learn more about the differences between activated carbon filters and ozone generators in air filters.

 

Carbon Filtration Technology

Carbon filtration technology works through a method called adsorption, where airborne contaminants are treated and trapped within the pore structure of a carbon media. The carbon feedstock is filled with other substances, such as organic matter, that fill the micropores or pores in the carbon filtration media in the carbon material. The carbon process will first remove these substances and leave pure carbon - the microscopic pores filled with other substances are now empty, greatly increasing the surface area of the carbon.

The carbon filtration process is designed to efficiently capture the large amount of contaminants in its filter media, and each piece of carbon is designed to provide a large surface area to maximize the exposure of contaminants to the filter media. Typically, carbon filtration media is activated with a positive charge designed to attract the negatively charged contaminants present in the air. Some carbon filters are made from pure carbon, while others (the vast majority of carbon filters) are manufactured by adding chemical additives that make the carbon filter media larger and more porous to contain and trap contaminants on the carbon media.

 

How Carbon Filters Work

As we discussed previously, carbon is a powerful absorbent that absorbs contaminants and draws them into the filter media. The particles/granules of carbon provide a large surface area structure on the filter media to maximize the ability to capture contaminants within the filter media, which in turn will help improve the overall indoor air quality in a given indoor environment. Approximately one pound of activated carbon has a surface area of 100 acre-feet.

When the carbon surface is activated to allow more contaminants to be captured on the media filter, this will mean that the carbon undergoes a specific activation method that is a two-stage process. The carbon material (whether it is nut shells, wood, coal, etc.) is carbonized, a process that is activated by heating it to about 600 degrees Celsius in an environment without oxygen so that it does not burn. When carbon is exposed to oxidizing agents such as oxygen, steam or carbon dioxide in a superheated environment, it activates carbon sites, which open pores on the carbon surface and greatly increase the surface area. Thus, when there is a higher surface area, it imparts a positive charge to the carbon, which will attract particles passing through the filter and bind them to the carbon's media surface.

What is Activated Carbon

图片
Activated carbon is one of the most common adsorption media   used on filters to control indoor air quality and reduce pollutants. The popularity of activated carbon is due to its inherent ability to adsorb most organic chemicals due to the large surface area created by the increased activation on the carbon/charcoal surface. When it comes to the capture and control of gaseous compounds present in the indoor air space, activated carbon will quickly and effectively trap these contaminants on this activated filter media. In some cases, the charcoal/carbon material will be treated with additional chemicals during the activation of this material, which will be done through the use of a chemical called potassium permanganate. Potassium permanganate is used in activated carbon filter media to help attract reactions between the carbon media and the oxidation of polar or low molecular weight compounds. In addition, many manufacturers use this chemical additive on carbon filters to help extend

Waste Carbon Recovery for Environmental Sustainability

图片
Used granular (GAC) or extruded (EAC) activated carbon can be recycled through thermal activation, which involves treating the used carbon in a high temperature activation oven at 850°C or above. Recovery by thermal regeneration is only one of the steps in the complete service package. The recovery process consists of two main processes: 1) reactivation process and 2) tail gas treatment and energy recovery process.     The reactivation process itself can be subdivided into four steps. 1) Drying of used carbon The used carbon is fed into the furnace and heated from ambient temperature to 105 - 110°C. Water and some low boiling compounds are evaporated and released into the furnace atmosphere. As long as there is water in the pores,  the temperature of the carbon  remains between 105 and 110°C. 2) Desorption of low boiling point organics. As the carbon dries, the temperature increases further to about 450°C. During this temperature increase, various organic compounds are desorbed from th
