Domestic Wastewater Influent Treatment in Reservoir B of Lampung University Using Constructed Wetlands (CWs)

Year: 2025

Type: article

Abstract: This study aims to analyze the effectiveness of the Constructed Wetlands (CWs) method in improving the quality of domestic wastewater before it enters Resevoir (Embung) B at Universitas Lampung. Embung B, which has the largest storage capacity on campus, also receives domestic wastewater (grey water) from residential areas and a terminal. The CWs method was applied using bamboo water (Equisetum hyemale) and water jasmine (Echinodorus palaefolius), with and without the addition of moss. Water quality parameters such as pH, TSS, BOD, COD, NH?-N, TDS, EC, temperature, and DO were tested. The results show that the combination of bamboo water with moss (P3) and water jasmine with moss (P4) was the most effective in reducing pollutant concentrations, with several parameters such as TSS, pH, and NH?-N meeting the domestic wastewater quality standards in accordance with Government Regulation No. 22 of 2021. Although BOD and COD did not fully meet the standards, there was a significant reduction compared to initial conditions. These findings suggest that the CWs system has potential as an eco-friendly and cost-effective technology for domestic wastewater treatment, especially in small-scale environments such as campuses or residential areas.
