What Will Affect The Service Life of Coconut Shell Activated Carbon Water Filter Cartridge?

Generally speaking, the service life of coconut shell activated carbon filter cartridge used in water treatment is 2-3 years, but this is a general calendar value. Its specific operating time is easily affected by many factors such as the quality of raw materials of coconut shell activated carbon water filter. The specific surface area of good-quality coconut shell activated carbon should be 1000m2 / g, and the mechanical strength should be above 90%.  With strong adsorption capacity and fast filtration speed,It is not easy to move due to particle formation, and impurities such as organic matter in water are not easy to block in the coconut shell activated carbon filter layer.

What will affect the service life of coconut shell activated carbon water filter cartridge?

  1. Water output.

 Assuming that the daily water output is large, the service life of the coconut shell activated carbon water filter cartridge will be relatively shortened, and each kilogram of coconut shell activated carbon can control 20 tons of water filtration capacity.

2. Water temperature.

The higher the water temperature, the stronger the adsorption capacity of the coconut shell activated carbon cartridge; but when the water temperature is higher than 30 ° C, the adsorption capacity of the coconut shell activated carbon filter will reach its limit, and its adsorption performance will gradually decrease.

3. PH value of water quality.

When the water quality is acidic, the adsorption capacity of the coconut shell activated carbon water filter cartridge for anionic substances is relatively weakened; when the water quality is alkaline, the adsorption capacity of the coconut shell activated carbon water filter for cationic substances is weakened. Therefore, the pH value of the water quality is unstable, which will also affect the adsorption capacity of the coconut shell activated carbon water filter. The adsorption capacity of coconut shell activated carbon cartridge is directly proportional to the contact time with water. The longer the contact time, the better the filtered water quality.

In general, we can use hydrochloric acid to modify the coconut shell activated carbon filter in practice to improve its adsorption performance. Similarly, in the process of using coconut shell activated carbon filter, we can use the chemical properties of the surface of the adsorbent and the adsorbent to find more effective adsorption methods through product experiments to improve our use efficiency and purification efficiency.

The above is our summary of the factors affecting the life of coconut shell activated carbon filter cartridges by Huatan Filter. We hope to help you understand the activated carbon block products.

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.
