Abstract: The main Aim of this work was to study the degradation and removal of acetyl salicylic acid using aerobic and anaerobic wastewater treatment and optimization of the conditions to improve the removal of pharmaceuticals. The result of the studies showed that ASP and UASB reactors treated acetyl salicylic acid (300 mg/litre) effectively giving more than 90 % of removal efficiency, if sufficient acclimatization period is provided.
