Why Do You Need A Carbon Block Filter in Your Home?

As people pay more and more attention to health and environmental protection, one of the problems that we urgently need to solve in our daily life is the water quality problem of tap water. Although it has been pre-filtered before being delivered to each household, there may still be a large amount of chemicals in the water, some of which are likely to be carcinogenic. Fortunately, people have invented a very clever solution: the use of carbon block filters.

We know that there are many chemicals, particles, bacteria, organic matter and toxins in tap water before it is pre-filtered by the water supply company. Due to the different water quality control standards implemented by different countries and regions, or the use of water filtration equipment and water quality monitoring equipment are not the same,these directly lead to the difference in the quality of tap water in the residents of various regions.

For running-water companies in many countries, how to effectively treat and filter out the chemical organic matter and toxins hidden in tap water is a challenge they face. Tap water comes from natural springs, reservoirs or other sources of water (such as farmland, lawns, street and industrial runoff).

For health and safety reasons, the water company will filter and disinfect the water first when it is used, whether it is directly used as drinking water.They usually use chemicals such as chlorine to disinfect water. Other chemicals may also be incorporated into the water during the disinfection process, such as volatile organic chemicals, bromates, fluorides, sulfates, nitric acid, and even radioisotopes such as radium. These may be by-products produced after the water has been sterilized. In any case, one or more of them may exist in most tap water and need to be filtered out.

In addition, water needs to pass through a series of long pipeline networks as it travels to individual homes. During this process, bacteria or other impurities attached to the water pipes would have a good chance of contaminating the water again.

Faced with so many unforeseen potential threats, carbon block filters provide the most powerful line of defense for people’s drinking water safety. We can’t control the water quality in the outside utility system, but we can install a carbon block filter in our home to make the water in our home better protected from potential hazards.

The effectiveness of the carbon block filter is due to the incredible nature of activated carbon making it the most promising and effective water filtration solution.The activated carbon filters manufactured by HUATAN Company all use NSF-certified coconut shell activated carbon as raw materials, and pass strict quality management and product inspection in the production process to ensure that each product can meet the qualified international standards.

Environmental Protection Is The Most Important Mission for All Carbon Filter Companies

Due to the advantages of developed pore structure, activated carbon blocks are regarded as the most excellent adsorbent and catalyst carrier, and are widely used in chemical, metallurgical, petrochemical, pharmaceutical, food, light industry, military and other fields. As an important purification material for gas and water contaminant treatment, activated carbon filter have played an increasingly important role in the field of environmental protection  in recent years. Its typical applications include organic solvent recovery, desulfurization and denitrification, adsorption and concentration of organic vapors, catalytic combustion, sewage treatment and deep purification.

The environmental protection industry is an important market and service target for activated carbon filter companies. More and more activated carbon block manufacturers are beginning to work on the research and development of new activated carbon filter products required by the environmental protection industry, and make their due contributions to the promotion of environmental protection industry products and environmental protection.

The adsorption characteristics of activated carbon are determined not only by its pore structure but also by its chemical composition. There are two types of impurities in activated carbon. One is represented by chemically bonded elements, that is, oxygen and hydrogen. The other type of impurity is ash, which is a non-organic part of the product. Ash content is an important technical indicator for the manufacture of activated carbon filter cartridges. The surface oxygen-containing groups are a carbonyl group, a carboxyl group, a phenol group, a lactone, and an anthracene. The content and type of these two types of impurities depend on the source of the raw materials, the manufacturing process, and the surface modification.

In the application of  liquid pollutant treatment, activated carbon has outstanding filtration capacity for BOD, COD, organic chlorine, organic mercury, chromium, phenol, cyanide and most organic substances in wastewater. It is widely used  for wastewater treatment in papermaking, textile, printing and dyeing, sugar, brewing, pharmaceutical, tanning, coking, pesticide, organic synthesis, petrochemical, polymer synthesis, electroplating and other industries. It is also effective for water purification (such as drinking water, high purity water, non-ionized water, boiler water).

However, there are many factors that affect the effectiveness of water treatment. In terms of activated carbon itself, the main influencing factors are pore structure and surface groups. Only when the pore diameter / adsorbate molecular diameter > 1.7, its pore volume is the most effective, its highest utilization occurs in the range of 1.7 < pore diameter / adsorbate molecular diameter <3. As the D/d value increases, the pore volume utilization decreases. At the same time, the pore diameter should be selected according to the different regeneration methods. If it is selected for desorption (such as solvent recovery) or heating regeneration (if the adsorbed material is easily decomposed by heat), it is appropriate to choose D/d=36; In the regeneration process, and the adsorbed material is decomposed into smaller sizes due to the action of the regenerating agent, and D/d can be selected in the range of 1.73 when it is difficult to be adsorbed by the activated carbon.

In the application of exhaust gas and harmful gas adsorption, according to different functions, activated carbon can be divided into desulfurization carbon, solvent recovery carbon, deodorization carbon, ozone purification carbon, gasoline recovery carbon and the like. And Clients‘ requirements in this industry for such activated carbon block products are large adsorption capacity, weak water absorption, good reproducibility and low price.

Regardless of the application area, HUATAN, as a leading brand in China’s activated carbon filter industry, we believe that environmental protection should be an important mission for all activated carbon filter companies. We need to develop activated carbon rod products with different surface properties according to the target of pollution treatment to meet the needs of the environmental protection market and better protect the health of all of us.If you are interested in learning more about our activated carbon block or water filter products, you are welcome to contact us at info@watfilter.com.

8 Tips for The Use of Sintered Activated Carbon Blocks

The sintered activated carbon filter is a filterwhich is prepared 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. It integrates adsorption, filtration, interception and catalysis into one body, which can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the effects of decolorization and odor removal. However, there are many points that need special attention when using sintered activated carbon. Today we will share 8 tips for using sintered activated carbon.

1. The sintered activated carbon block has a large number of micropores and super strong adsorption capacity, and its adsorption performance is second only to the high-precision filter cartridge. The pore diameter of the sintered activated carbon block will gradually become smaller during the process of intercepting and adsorbing impurities, and the pressure drop of the filter cartridge becomes larger, and the flow rate becomes smaller.

2. The filtering effect of the sintered activated carbon block is proportional to the contact time of the filtered material with the activated carbon cartridge. Therefore, the wall thickness of the sintered activated carbon filter determines the effect of filtering the pollutants.

3. The pore size of the sintered activated carbon block filter cartridge should not be too large. Generally, the best pore size is 1-2 microns. Otherwise it will affect the adsorption and filtration effect of activated carbon on contaminant.

4. All activated carbon blocks should be careful to avoid the adhesion of a large amount of large particles (SS solid suspension) to the surface during use, as this will cause anaerobic biological growth, thereby reducing the adsorption effect of the activated carbon filter and producing other odors. Therefore, the precision of pp cotton filter (the pre-filter cartridge of the sintered activated carbon filter) must reach the standard of 1 micron, or the precision of the non-woven fabric wrapped with sintered activated carbon should reach about 1 micron.

5. When the sintered activated carbon filter is used after being placed in the hollow ultrafiltration wet film, we need to pay attention to thoroughly clean the protective liquid of the ultrafiltration membrane when it is used for the first time, and then connect the sintered activated carbon filter.Otherwise, the strong adsorption of the sintered activated carbon will instantaneously adsorb the alcohol and the silicone oil in the protective liquid, causing the filter catridge to be ineffective or even mold. (Other activated carbon filter cartridges should also be noted).

6. Granular activated carbon, alkaline ball, maifanite ball and negative potential ball (hereinafter referred to as “particle state filter element”) are easy to produce powdery substances. If these filter elements are placed in front of sintered activated carbon blcok, the generated dust will easily block the sintering activated carbon filter.Therefore, when using the filter, we recommend you to wash the granular material filter cartridge before use, until there is no black water or floating out and then connected to the sintered activated carbon filter cartridge.

7. If the particle filter cartridge and the sintered activated carbon filter cartridge are separated by an ultrafiltration membrane filter cartridge, it is necessary to ensure that the ultrafiltration membrane filter cartridge is not damaged, and the ultrafiltration membrane should be backwashed frequently to avoid high temperature, Otherwise, the impurities intercepted by the ultrafiltration membrane will be decomposed by the microbial bacteria and produce a rancid smell. These odors are immediately adsorbed by the sintered activated carbon block. After a while, our drinking water will have an odor (it can be washed with a large amount of water).

8. Sintered activated carbon filter has super strong adsorption effect. If it is placed behind the alkaline function filter cartridge, the alkalinity will be weakened.
