Biological activated carbon treatment process
Thread Content
I’ve read some materials indicating that the biological activated carbon process can achieve certain results in dealing with many difficult-to-treat pollutants. I wonder if any expert knows the specific processes involved as well as how to form a film, and what process conditions need to be taken into account! :) !
Activated carbon is used in wastewater treatment mainly in two ways: first, it is employed in post-biological treatment, where its adsorptive properties are utilized to reduce organic pollutants in water. It is generally not used for the pre-treatment of wastewater, as the adsorption capacity of activated carbon is limited; once this capacity is saturated, the activated carbon needs to be regenerated, otherwise it loses its usefulness. However, the equipment required for regenerating activated carbon is expensive, resulting in high investment costs. II. It can be applied in biochemical tanks; this process is generally referred to as fed-aeration. Sludge can be added in this way to improve the sedimentation properties of the sludge. Of course, it also has adsorption capabilities, and the results are good, but it is necessary to add the sludge at regular intervals. LZ, you can find the relevant parameters in \"The New Activated Sludge Process\".
