This thesis investigates the performance of pilot-scale vertical flow constructed wetlands for the treatment of primary-treated municipal wastewater, with a particular focus on the role of biochar as an innovative filling material. Four substrate configurations were compared: (i) gravel (PG), (ii) gravel with biochar (PGB), (iii) recycled HDPE plastic (PP), and (iv) recycled plastic with biochar (PPB). System performance was evaluated based on key parameters, including BOD, COD, DOC, TSS, NH₄⁺-N, TP, and PO₄³⁻-P. The results demonstrated that the addition of biochar enhanced the removal of both organic and inorganic pollutants, improving effluent quality. Moreover, the use of recycled materials such as HDPE incorporates the principles of circular economy by reducing the need for virgin resources. Overall, the findings highlight that biochar-enhanced constructed wetlands can serve as an efficient, low-cost, and environmentally friendly solution for municipal wastewater management, particularly in rural and semi-urban areas.
