The adsorption isotherm is shown for herbicides that belong to the triazines group.
For contact times from 8 to 12 minutes and superficial speed of approximately 12 m/h elimination would be practically 100%.
|Triazine compound concentrations||0,4 µg/l|
|Adsorption total capacity for 0’4 µg/l||22 mg de atrazina/g de carbon|
|Calculation: Daily pesticide quantity||960 mg|
|Approximate carbon for elimination||50 g|
Note: Data calculated under optimal operation conditions. It must be corrected because the carbon will adsorb organic material from water and will suffer certain abrasion due to chlorine or other oxidation molecules.
Periodic analyses of intake and output filters must be done to check the performance.
