Process of Life Cycle Installation of Wastewater Treatment and up to Water Reuse

Abstract

The life cycle assessment (LCA) of the wastewater treatment plant (WWTP) has several categories in the resulting impact analysis. One of them is a wastewater treatment plant on campus or university. Various emissions from WWTP and their impact factors are analyzed using software and utilizing the Eco-inventory database. Recycled water from factories has a positive impact on the categories assessed. System treatment overrides the effects of recycled water in other types such as potential terrestrial eco-toxicity, global warming potential, particulate matter formation, fossil depletion potential, and others. However, untreated sewers’ social effects and the environmental impact of compost generated by the system have not been thoroughly analyzed by a more holistic analysis. By using the LCA method, these results can be seen in Enim River’s environment expressed in GWP units (global warming potential) and human health expressed in ODP units (Ozone Depletion Potential). Several studies have also been conducted on LCA, which has problems with wastewater. One of the most recent research analyses various wastewater treatment strategies, such as aerobic against anaerobic, chemical versus chemical, and biological combinations. The Enim River is found in the Indonesian province of South Sumatra. The Muara Enim Regency area is where the river flows from upstream to downstream. The Enim River is a child of the Lematang River. The GWP value had a GWP of 16% before being treated in wastewater, and it had a GWP of 41.3% after being treated with sewage. This result means that treating wastewater requires energy to do so. Before treatment, the MDP value was 10.4%, and after treatment was 20.4%. However, further action after the management of wastewater gives significant value to the assessment of GWP, MDP, and ODP. The three results provided a reduction value for the reuse of treated water and reused as water needs.
