With the increasingly perfect environmental protection regulations and the concept of sustainable development gradually being widely accepted by the international community, activated carbon block filter is a valuable component that will continue to receive more attention.

In fact, a recent research report issued by an international authority estimates that by 2022, the global activated carbon industry market is expected to reach US $ 6.2 billion.

Application fields of activated carbon blocks Filters

Activated carbon block filters are mainly made by the extraction and processing of coal, wood and coconut husk. It has a unique porous physical structure that can adsorb and filter many fine impurities, making it one of the most widely used adsorbents on the market. It can be used in decaffeination, air purifiers (including industrial and consumer applications), water purification (including industrial and consumer applications), soil remediation, pharmaceutical product production, food and beverage production, gold recycling, metal surface treatment .

Market demand drives development of activated carbon block industry

With so many application areas above, it is not difficult to imagine that the global market demand for activated carbon blocks will always continue to rise. But what is driving this dramatic increase in demand? Recent reports from the global activated carbon block market provide some insights. According to reports, the driving factors for the rapid growth of the activated carbon block market include:

Increased demand for drinking water safety

The rapid development of global industrialization has also brought a certain degree of industrial pollution to cities. The wastewater of some factories is discharged directly into the external river without scientific treatment. This directly caused water pollution. As people’s awareness of drinking water safety continues to increase, the government has also begun to increase investment in water purification equipment on infrastructure. As one of the most critical components in water purification equipment, activated carbon blocks play their role with excellent filtering and purification performance.

Recovery of the automotive industry

Global industry analysts predict that the recovery of the automotive industry will also drive demand for activated carbon blocks. Activated carbon canisters are used in vehicles to reduce hydrocarbon emissions and improve engine performance. As demand for more vehicles continues to rise, the use of activated carbon blocks will gradually increase.

Improvement of environmental protection policies

The continuous improvement of environmental protection regulations indicates that people need to increase the use of environmental protection equipment while building cities and developing industries. As one of the essential materials for many environmental protection equipment, activated carbon block is widely used in many fields such as energy purification and water cleaning.

In addition, the global industrial analysis report predicts that more and more countries require that disinfectants used for tap water cleaning and disinfection must strictly control the concentration of drinking water chemicals. This may also be driven by some benign growth in demand for activated carbon. .

As the global environmental recovery and protection consciousness continues to increase, many factors have jointly driven the demand for this versatile filter material. The development of the activated carbon block industry will continue to usher in more new growth points.

1 Weight Comparison

The most remarkable feature of the activated carbon filter is that there are many internal pores which determines its strong adsorption capacity.The more pores and the more complex the structure, the stronger the adsorption capacity and the better the quality of the filter cartridge. However,we can’t identify it by eye when buying. From the perspective of material density, the more internal pores, the lower the density, and the lighter the weight of the same volume of carbon block filter. Therefore, we can identify it by hand. The weight of the good quality activated carbon filter is relatively lighter than that of the poor quality activated carbon filter.

2 Indicator Observation

There are generally three indicators for identifying the quality of activated carbon filter: iodine adsorption value, carbon tetrachloride adsorption value, methylene blue adsorption value. If the higher these three indicators on the filter, the stronger the adsorption capacity they have, and the better the quality of the activated carbon filter is. The three values respectively represent the ability to adsorb organic matter, gas, and discoloration.However, the adsorption performance of the carbon rod filter has a life cycle, and it should be remembered to be replaced on time during use.

3.Combustion Test

Combustion is a commonly used method for identifying the quality of a substance. It is a destructive test and is suitable for the identification of activated carbon blocks. First of all, you can break the filter cartridge a little bit, then take a little bit of activated carbon from the filter, burn it on the fire, and then take it off. If it turns into black ash immediately, it is really activated carbon; if it turns into white ash,it  is ordinary charcoa,cause charcoal is produced when the raw materials are not fully burned, the internal pores are much less than that of activated carbon, and its adsorption capacity is naturally poor.

The Role of Activated Carbon Block Cartridge in The Water Filter

Activated carbon is a black powder or block, granular, honeycomb amorphous carbon or a well-arranged crystalline carbon.

Activated carbon blcok is a very good adsorbent material which uses charcoal, bamboo charcoal, various shells and high-quality coal as raw materials,and is processed by a series of  by physical and chemical methods such as crushing, sieving, catalyst activation, rinsing, drying and screening.It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb harmful substances in tap water to achieve decolorization, odor removal and filtration of chemical pollution and volatile organic substances.

What is the role of activated carbon block in the field of water filtration?

Activated carbon block is widely used in industrial production and family life especially in the field of water purification due to its strong adsorption performance.In the case of drinking water applications, once the drinking water is contaminated, it is easy to produce odor.First of all, it will make people feel very uncomfortable in the senses, and secondly it may also cause harm to human health.One of the important performance of activated carbon block is that it can adsorb and filter the pigments and odors in the water, such as the rust smell produced by rust in the water, the yellow rust water color, the odor generated by the sulfide water, the earthy smell produced by the muddy water, and the mold and smashing smell produced by the animal and plant corpses.

Activated carbon cartridge has a well-developed pore structure and a large specific surface area. It has good adsorption capacity for inorganic or organic substances and colloidal particles in gases and solutions. The working principle of the activated carbon filter is to use the porous solid surface to adsorb and remove organic or toxic substances in the water to achieve the effect of purifying water.

The adsorption of organic matter by activated carbon cartridge is affected by its pore size distribution and organic matter characteristics, which is mainly affected by the polarity and molecular size of organic matter. For organic matter of the same size, the greater the solubility and the stronger the hydrophilicity, the worse the adsorption of activated carbon on it. Conversely, it has strong adsorption capacity for organic substances such as benzene compounds with low solubility, poor hydrophilicity and weak polarity.

What are the classifications of activated carbon filter cartridges for water purifiers?

UDF granular activated carbon filter: It can effectively remove odor in water, such as chlorine (bleaching powder), improve the taste of water, and effectively avoid the production of carcinogens such as chlorine and chloroform.

CTO activated carbon filter: It can deeply absorb harmful substances such as color, odor and residual chlorine in water and use micropores of charcoal activated carbon to retain fine particles and colloidal suspension.

Post-activated activated carbon: It can effectively remove the odor of water, inhibit the growth of bacteria, improve the taste of pure water, and increase the energy of water.

In summary, the activated carbon filter has an excellent effect on water purification. It not only removes the odor and odor, but also improves the purity of the water, and has a high removal rate for various impurities in the water,such as chlorine, phenol, cyanide, pesticides and other harmful substances.Therefore, activated carbon blcoks can be widely used in various types of large, medium and small water purification equipment.

3 Activated Carbon Filter Cartridges in Different Manufacturing Processes

In the water treatment industry, these terms such as sintered activated carbon, compressed activated carbon, extruded activated carbon, CTO are often mentioned or used, but many people do not really understand the difference between them. Sintered activated carbon filter cartridges, compressed activated carbon filter cartridges, and extruded activated carbon filter cartridges are named after their production process characteristics. CTOs are words that are known for their final shape. Although they have the same shape, the internal quality and production process are very different.

Sintered Activated Carbon Block Filter

The sintered activated carbon filter cartridge is made by mixing activated carbon powder material and polymer hot-melting pore-forming material, pouring into a special mold and sintering at a high temperature of 200-300 ° C; since the bonding material itself has pore-forming property, after being mixed with activated carbon, It maintains the characteristics of large specific surface area of activated carbon powder, and has excellent pore-forming properties and better filtration effect, which can more fully contact with liquid; however, the production capacity of sintered activated carbon filter is limited due to its complicated processing technology.

Compressed Activated Carbon Block Filter

The compressed activated carbon filter cartridge is mixed with activated carbon powder material and inorganic liquid binder, poured into a special mold, and is compressed by high pressure compression molding, and dried after being discharged from the mold; the activated carbon filter  produced by this method  has a relatively high carbon content and very good filtering effect. Since the pore size of the filter cartridge is mainly controlled by the particle size of the activated carbon, and the binder material of the compressed activated carbon filter cannot be pore-forming during the manufacturing process, the property of the filter cartridge is inferior to that of the sintered activated carbon.

 Extruded Activated Carbon Block Filter 

 The extruded activated carbon filter cartridge is mixed with activated carbon and ordinary hot melt resin, and then placed in a screw extruder for heating and extrusion molding. In this production process, the surface of the activated carbon is melted by the hot melt resin at a high temperature, which causes the plugging of some activated carbon micropores and affects its adsorption performance.However, extruded carbon filter cartridges have low production costs and can achieve high yields. The performance of the extruded activated carbon filter in use is relatively much worse than the previous two carbon block filters.

Benefits of Coconut Shell Activated Carbon Block Filter

Coconut shell is one of the latest and most promising material choices for activated carbon block filter manufacturers in recent years. Because the coconut shell activated carbon block has a larger surface area and a more general porosity, its micropore density is much higher than that of other materials. Coconut shell activated carbon has 50% more micropores compared to bituminous coal. This also means that the coconut shell activated carbon filter can better adsorb and filter volatile organic chemicals in the water.

In addition, it is easier for manufacturers to make coconut shell activated carbon. The use of coal and wood to make activated carbon produces large amounts of dust and fine carbon particles, which are rarely produced with coconut shells. At the same time, the use of coconut shell does not cause any damage to the tree, because coconut shell is a natural raw material that can be continuously regenerated throughout the year, and it will regenerate as the coconut grows. Therefore, coconut shell is recognized as the best green activated carbon block raw material.

We summarize the benefits of coconut shell activated carbon filter as follows:

1. Coconut shell activated carbon is sustainable. Coconuts grow in tropical climates and can survive for many years. This allows them to continuously produce carbon, and they are growing all year round. Coconut can be picked three to four times a year, thus ensuring a stable source of coconut shell activated carbon filter.

2. Coconut shell is a green source of high quality activated carbon. We can think of coconut trees as naturally stored carbon. They absorb carbon dioxide from the atmosphere and store carbon, which produces oxygen during the process. By cultivating coconut trees and continually burning their coconut shells into carbon blocks, these carbon blocks do not produce too much dust and other contaminating particles during the manufacturing process due to their fixed form.

3. Coconut shell activated carbon block has high porosity and high density of micropores, which can best filter pollutants. Another benefit of the microporosity of coconut shell carbon is its high mechanical strength and excellent hardness and wear resistance. Thanks to these advantages, the most significant benefit of using a coconut shell activated carbon filter is that it can filter cleaner water than other activated carbon materials.

HUATAN is an NSF-certified carbon block water filter manufacturer. All our activated carbon cartridge and water filter products are made of the highest quality coconut shell and can be sold after our internal strict quality inspection.
