Abstract
This research investigates the effectiveness of granular activated carbon (GAC) in eradicating micropollutants (pharmaceuticals, dyes, pesticides….etc.) from treated effluents of municipal wastewater treatment plants. By using methylene blue as a model representative organic micropollutant, the study examines the mechanisms involved in its removal. Through batch experiments, the study demonstrates impressive removal efficiency; displaying an absorption capacity of 349.3 mg/g. Factors such as contact time, initial dye concentration and GAC particle size have an impact on the removal efficiency while pH levels (2-11) minimally affects the absorption process. The kinetics are analyzed utilizing Langmuir and Freundlich models. In continuous flow experiments, lab-scale GAC filters sustain remarkable removal efficiency for the target across various flow rates. The study also addresses scalability, revealing a reduction in removal percentages from 93.9% to 88.8% as flow rates increase from (1m3/h) to (5m3/h). These discoveries provide crucial insights into devising effective strategies to combat the potential dangers posed by micropollutants.
