1. What is the difference between dry molecular media and activated carbon?
Drymolecular media uses chemisorption: pollutants react with the filter media, and gaseous pollutants are converted into harmless substances and retained inside the filter media, preventing secondary pollution. Dry molecular mediauses chemisorption to effectively remove harmful substances from gases. It provides high-efficiency, high-capacity pollutant removal and long service life, while media life can be monitored and predicted.
Activated carbon uses physical adsorption: pollutants enter the pores of the filter media, and adsorption occurs on the surface of the filter media. Generally, the larger the specific surface area of the filter media, the more pollutants it can adsorb. This is a reversible adsorption process, with the possibility of secondary pollution.
2. Are dry molecularmedia toxic?
When used correctly, molecular media are non-toxic and harmless to the environment, workers and protected objects.
Large quantities of molecular media may pose hazards to the environment if used or disposed of improperly.
When properly handled,molecularmedia are harmless to humans, animals and the environment.
3. Are dry molecular media a source of pollution?
Drymolecular media continuously remove harmful gases from the air through chemical absorption. During this immediate chemical reaction process, contaminated gases are first adsorbed or captured on the surface of the filter media, and are then decomposed by the filter media through chemical reactions into harmless solids, which are retained inside the filter media. This ensures that once contaminated gases are removed from the environment, they cannot return to the air.
4. Can molecular media be used in other filtration system?
Yes.
The air volume, fan pressure and pressure drop of the filter media in the existing filtration system need to be calculated. Our professional technical engineers can assist with project planning, design and calculations.
5. How can I determine whether the air quality of an environment using chemical filters is acceptable?
In corrosive gas control applications, atmospheric corrosion level classification monitoring coupons are generally used for periodic monitoring. If the test results meet the G1 mild corrosion level specified in ISA 71.04, the environment is considered acceptable. If the G1 level is exceeded, the filtration media needs to be replaced.
In malodor(odor) removal applications, controlled environments or exhaust outlets are required to achieve zero odor.
6. How long domolecular media or chemical filters last?
For bulk-filled molecular media, it is recommended to take a sample every 3 months after commissioning and send it to the EcoKeeper Laboratory to test the remaining service life of the media.
For pure activated carbon media, it is recommended to take media samples at fixed intervals and send them to the laboratory for CTC activity testing to analyze the remaining service life of the media.
As with dust and particulate filters, the service life of a chemical filter depends on the type, air flow and concentration of the contaminants in the filtered gas. If the type and concentration of pollutants are known, the service life can be accurately calculated.
7. Does moisture affect the filtration results?
No.
Unlike traditional activated carbon media, the stable operating temperature range for molecular media is -20℃~51℃, with a relative humidity of 10%~90%. EcoKeepermolecular media have numerous successful applications in hot and humid tropical regions as well as cold and dry environments.
8. How do I determine which filtration media to use?
For different gaseous pollutants and application requirements, combined with searches of the EcoKeeper environmental application database, we provide filtration media with different functions, shapes and dimensions.
9. Can the removal efficiency of molecular media or chemical filters be predicted in advance?
If the type and concentration of pollutants and the air flow are known, we can accurately calculate the removal efficiency of the filter.
10. How should used filtration media or filter products be disposed of?
Materials used to remove toxic substances should be tested and classified as solid-waste chemicals.
In accordance with Chinese laws and regulations, both general solid waste and hazardous waste materials after use must be handed over to solid waste treatment facilities for harmless treatment.
11. What are the procedures for controlling air quality in collection environment?
Step 1, Assessment: Conduct a comprehensive assessment of ambient air quality and use CCC atmospheric corrosion test coupons to determine whether the controlled environment meets the required standards and technical indicators;
Step 2-Control: Based on the test data or report from Step 1, control the air quality of the controlled environment. Use EcoKeeper molecularmedia and equipment to bring the controlled environmental air quality into compliance with the required standards and indicators;
Step 3-Monitoring: Conduct long-term monitoring of ambient air quality. Use CCC atmospheric corrosion test coupons and the ÅirIQ Atmospheric Corrosion Monitor to ensure that the controlled environmental air quality meets the requirements of relevant standards;
Step 4-Optimization: Summarize and analyze the data obtained from long-term environmental air-quality monitoring. EcoKeeper develops a preventive maintenance plan for users to maximize equipment efficiency and optimize the service life of molecular media.
12. What are the differences between CCCatmospheric corrosion test coupons and the ÅirIQ Atmospheric Corrosion Monitor?
When using CCC atmospheric corrosion test coupons, the test coupon is generally placed in the environment being tested for approximately30 days. The thickness of the corrosion film formed on the surface of the test coupon and the possible types of contaminants are then analyzed. This technology reflects the cumulative rate of corrosion reactions in the environment, evaluates the average destructive capability of corrosive gases in the tested environment during the test period, and identifies the categories of corrosive gaseous pollutants. CCC atmospheric corrosion test coupons can provide continuous environmental assessment and classification.

ERMs atmospheric corrosion monitors can continuously monitor changes in corrosion in a controlled environment in real time, while also providing temperature and humidity measurements. Temperature and humidity affect the corrosion process and are also two of the key parameters that need to be controlled in a protected environment. The instrument can operate independently, connect directly to a central computer, or form a monitoring network with other similar instruments. Monitoring data can be downloaded to a computer for processing, editing and plotting. Corrosion level, temperature and humidity can be updated once every minute. These data can be used to establish an environmental corrosion database and provide a comprehensive and accurate assessment for protecting the protected objects.
13. What is an Angstrom?
The Angstrom is a non-SI unit of length, with the symbol Å. 1 Angstrom equals 10-10(one ten-billionth)meter. It is mainly used to measure extremely small lengths. The unit is named in honor of Swedish physicist Anders Jonas Ångström. When studying corrosion rates in monitored environments, atmospheric corrosion level classification monitoring coupons are used, with the corrosion thickness of copper and silver expressed in Angstroms.
