Abstract
Wastewater treatment is a crucial process to ensure the protection of the environment and public health. Planted filters, also known as constructed wetlands (CWs) represent a pioneering approach to wastewater treatment, leveraging the natural processes of wetland ecosystems to purify water. This technique involves the use of planted macrophytes, such as Phragmitesaustralis and Cyperus papyrus, which are instrumental in removing contaminants through physical, chemical, and biological interactions. Unlike conventional treatment methods, CWs offer a sustainable and cost-effective solution, minimizing energy consumption and chemical usage. The importance of this technology lies in its ability to address the growing demand for efficient wastewater management, particularly in regions with limited access to conventional infrastructure. By utilizing macrophytes' natural filtration capabilities, CWs not only enhance water quality but also contribute to ecological conservation and the restoration of wetland habitats. This study aims to evaluate the efficiency of constructed wetlands (CWs) for treating wastewater through the use of planted macrophytes, specifically Phragmites australis (common reed) and Cyperus papyrus (papyrus), arranged in series and parallel configurations.The experiment showed the effectiveness of Phragmites plant and Cyperus plant infiltering sewage water, whether the macrophytes filters are planted in series or in parallel.The removal percentage of NH4+ reached 61.76% inA,B and A+Bbasins, the removalthe percentage of BOD5 reached 69.48 in AB and BA basins, the removal percentage of COD reached 5.77 in A, B and A+B basins, and the removal of conductivity reached 75.67 in ABand BA basins.The results obtained indicate that the activity ratio is balanced in both cases. In the case of sequential filter planting, the results showed more effective performance for some parameters compared to parallel filter planting, and vice versa. This proves the effectiveness of both methods, whether used individually or together, as well as the effectiveness of Cyperus papyrus and Phragmites australis in removing pollutants from wastewater.
