Chemical Filter
What is Chemical Filter?
Chemical filter is the filtration system designed to remove chemical pollutants from air or fluids, crucial for protecting both customers and machinery from contaminations.Chemical filter plays a crucial role in manufacturing facilities by effectively removing gaseous pollutants, reducing product defects, surface contamination, and other flaws, thereby enhancing productivity and quality. Moreover, these filters help reduce environmental pollution during the production process, cutting waste and costs, further reducing carbon emissions, fostering a positive cycle for both businesses and the environment.
Advantages of Chemical Filter
Efficient processes
In any facility, processes are interconnected. Any inefficiency in one area will have a domino effect – and could become costly for the plant as a whole. Efficient chemical filtration systems at critical points in the process operation can help reduce the risk of burgeoning operating costs and improve the quality of the end product.
Streamlined operation
Each chemical process system that we recommend has been developed to address specific filtration challenges. For example, industries such as oil & gas and the chemical industry for example, usually work with liquids that are difficult to separate as they contain emulsions. Without the right solution, process performance will be affected. Water and wastewater facilities, on the other hand, need to remove both solid particulates and emulsions. Meanwhile, many plants require automated solutions. Thus, each chemical filtration solution must meet the process need – and integrate seamlessly to allow streamlined operations.
Reduced downtime
When processing feed stock, particulate removal is of great importance. Solid contaminants interfere with the chemical process, reducing the quality of the product. These contaminants can also lead to the corrosion and the deterioration of process equipment and piping over time, causing costly downtime for maintenance and repair.

The chemical filter is a filter device in which a bundle of bulked fiber filaments (d20-50m) with heavy hanging is suspended at the lower end and is suspended on a porous plate provided on the upper part of the filter as a filter medium. The portion of the fiber bundle near the porous plate has several capsules. When filtering, the capsule is first filled with water, forcing the surrounding fiber bundles to make it dense, and then the water flows upward through the fiber pores from bottom to top. When cleaning, first drain the moisture in the bag, cancel the extrusion of the fiber bundle, so that the fiber bundle is restored to a fluffy state under the joint action of gravity and expanded fiber elasticity, and then stirred and scrubbed with air and water.
Since the fiber used as the filter element is a flexible and soft material, the diameter of the filter material can reach tens of microns, and there is a large amount of void space in the filter material layer. Different fiber porosity can be obtained by using the extrusion conditions of the fiber bundle, and the efficiency and resistance of the filter can be controlled within a set range, which solves the problems of traditional filtering equipment such as valveless filter, siphon filter, mechanical filter, etc. All of them use quartz sand and other granular filter materials for filtration, and the filtration accuracy is limited by the large particle size of the filter materials. The small diameter of the filter material greatly increases the specific surface area and surface free energy of the filter material, and increases the impurities in the water. The contact opportunities of the particles with the filter material and the adsorption capacity of the filter material are improved, thereby improving the filtration efficiency and retention capacity.
Compared with the valve-less filter with quartz sand as the filter material, the fiber filter with fiber as the filter material has the advantages of high filtration efficiency, fast filtration speed, large amount of sewage interception, large periodic water production and low self-consumption. It occupies less land. It has the characteristics of small footprint, and at the same time solves the problems existing in the original process, and has high economic and social benefits. If the cleaning technology of the filter material can be improved, the internal structure of the filter equipment can be simplified, so that it has the ability to directly treat high turbidity water, and better solve the problem of large fiber filtration equipment, it can be more widely used in the field of water treatment.
How to Choose Chemical Filter
Application areas and pollutants
When choosing a chemical filter, it’s important to consider the application area and the types of pollutants. Different applications and contaminants, such as organic gases, inorganic gases, ozone, and dust, require specific filter media and filtration efficiency to ensure effective pollutant removal.
System requirements and limitations
It’s also crucial to take into account the filtration system’s requirements and limitations, including flow rate, pressure, and temperature. Each system has unique needs, so selecting the right chemical filter is essential for proper operation and achieving the desired filtration results.
Lifespan and replacement cycle
The filter’s lifespan and replacement cycle are important factors. Different chemical filters vary in longevity, so monitoring the actual concentration in the facility is necessary to choose the right filter and avoid premature replacements or using expired filters, which can decrease filtration effectiveness.
When selecting a chemical filter, consider application areas, pollutants, system requirements, and filter lifespan to ensure effective filtration, improve product quality, and enhance production efficiency.
Application of Chemical Filter in Electronic Industry
In high-tech enterprises such as integrated semiconductor devices and microelectronics, with the increase of product process complexity and the reduction of product process line width, gaseous molecular pollutants in the air (hereinafter referred to as amc) often lead to product yield degradation and performance degradation and failure,chemical filterplays an important role, then, let's learn about the application of chemical filters in the electronics industry!
The international association of semiconductor equipment and materials gives a classification system for amc gases in semi f21-95 and f21-1102. The standard is applicable to the clean environment of the semiconductor industry and specifies four "standard ranges": Acid (ma), alkali (mb), condensate (mc) and impurity (md).
The hazards of amc, take the circuit board as an example: The common chemical faults of the circuit board are copper creep corrosion and silver plating corrosion of surface mount components. Sulfur-containing gases and moisture will corrode all copper plating on the circuit board. The resulting copper sulfide will cause the circuit board to creep and may cause short circuits between adjacent support features. At the same time, sulfur-containing gases can corrode silver, forming silver sulfide; the accumulation of large amounts of silver sulfide can generate mechanical stress, destroy the integrity of the package, and cause further corrosion until all the silver in the part is consumed, causing an open circuit.
In a clean room, pollution includes not only dust particles in the strict sense, but also solids, liquids, gases, heat, electromagnetism, etc. That have any interference effect. Most clean rooms are equipped with chemical filters or high efficiency filters. They are very effective for controlling particles above 0.5 microns, but they are not effective for small molecule amc, which is filtered by traditional physical filtration. There is a risk of secondary pollution, which requires the use of chemical filters, which is inseparable from the working principle of chemical filters.
Chemical filters selectively adsorb harmful gas molecules, rather than mechanically "filtering" odors, corrosive gases, toxic gases and other impurities in the air like ordinary filters.
Chemical filters usually use activated carbon, activated alumina, ion exchange resin and other purification media as a filter material. Zhongjian south provides a variety of chemical filtration products, which can achieve the effect of removing pollutants through reasonable configuration.
Different industries and different places have different requirements on the concentration of gaseous pollutants after purification. In industries such as semiconductors and microelectronics, the use of chemical filters can effectively remove "molecular contaminants" and protect sensitive electronic systems and printed circuit boards. The influence of acid gas and moisture can improve product quality, increase product yield, and protect the health of workers.
What Is The Adsorption Principle Of Chemical Filters?
Activated carbon selectively adsorbs gases instead of mechanically "filtering" impurities. There are a large number of micropores on the surface of activated carbon, most of which have a pore size of less than 500 (1=10-10 meters). The total internal surface area of the micropores per unit material is called the "specific surface area", which can reach 700~2300 square meters/g. When it comes to adsorption, harmful gases in the air are called "adsorbates" and activated carbon is called "adsorbent". Due to the gravity between molecules, the adsorbate sticks to the inner surface of the micropores. If it is accompanied by a chemical reaction, it is called chemical adsorption, otherwise it is physical adsorption. While the adsorbent material is adsorbed on the adsorbent, part of the adsorbent material is separated from the adsorbent, which is called "desorption". During use, the adsorption capacity continues to weaken and the removability increases. When it increases to a certain extent, the activated carbon is discarded. Sometimes, by heating or fumigating with water vapor, the adsorbate will separate from the adsorbent, regenerating the activated carbon.
On the Characteristics of Chemical Filter




The chemical filter is mainly made of a high adsorptive substance, the chemical adsorbent has an appearance of red spherical or black columnar particles, and the adsorbent of the chemical filter can continuously purify toxic gases, corrosive exhaust gases, malodors and the like in various environments. The processing technology of the chemical filter uses a unique processing technology, and the chemical filter has the following characteristics:
1. Good adsorption and good stability.
2. Redox method plus physical adsorption, purify the air, purification has no special requirements for the environment, will not produce side effects.
The purification process is irreversible and will not cause secondary environmental pollution.
4. Strong applicability, can be used under normal conditions, thorough purification and high efficiency.
Chemical filterlow operating costs, daily management is relatively simple, do not need to clean every day. The concentration of pollutants after purification can be controlled at ppb(10-9) level, and the purified air can reach g1 standard. Chemical filters using chemical adsorbents as raw materials can be combined with a variety of other substances to achieve a one-time purification of a variety of complex pollutants.
These characteristics of the chemical filter ensure that it can be used in all walks of life and make a corresponding contribution to our physical health and environmental protection. The main function of chemical filters in the field of heavy industry is to prevent corrosive gases or toxic and harmful gases. In the field of light industry, chemical filters can remove malodorous gases and volatile toxic gases to protect human health. The commercial environment is similar to that of light industry, and it has the effect of purifying the air in the working environment, which can ensure that furniture and other equipment are not corroded. Precise instrument room, laboratory, control room for valuableschemical filterto protect the machine from corrosion, extend the use time of the machine, improve the environment, and increase the corresponding productivity.
