Calculation of the amount required for activated carbon adsorption equipment
Thread Content
I would like to ask an expert to explain the calculations related to the amount of activated carbon required for activated carbon adsorption equipment, as well as the calculation of the replacement cycle
The specific density and porosity of activated carbon can vary from one manufacturer to another; it is best to consult the activated carbon producer for details
This is related to the filtration wind speed; once the filtration wind speed and flow rate are determined, it is possible to calculate the filtering area required for activated carbon. Generally, the thickness of each layer of activated carbon should be no less than 200 mm. The number of layers can be determined based on the requirements of your equipment. From this, the volume of activated carbon needed can be calculated. Depending on your specific circumstances, you can choose the appropriate specification for the activated carbon. By referring to relevant information or consulting the manufacturer regarding that specification, its density can be determined, and thus it will be possible to know how many tons are required.
If you are referring to granular activated carbon filters, then the height of the activated carbon layer is usually around 1.0–2.5 meters, with this height being determined based on the volume and quality of water. For the specific calculation of floor height, there are formulas recommended by Bohart and Adams, but the values involved need to be determined through experimentation. I only managed to get this far by experimenting on my own at the company.
