WASTEWATER TREATMENT PLANT LIFE CYCLE ASSESSMENT: A CASE STUDY IN BATU CITY AND KEPUTIH WASTEWATER TREATMENT PLANTNIEKE KARNANINGROEM AND MAS AGUS MARDYANTOAbstract The contribution of environmental impacts due to the treatment process of Kota Batu IPLT sludge treatment with a life cycle assessment (LCA) approach is that Aquatic acidification has an impact of 0.28 times, Non Renewable Energy has an impact of 0.25 times, and Global Warming has an impact of 0.27 times when compared to the Keputih IPLT. The difference in impact from the processing of sewage sludge produced by each IPLT is influenced by the resilience of the treatment unit to the burden of wastewater, the number of people that can be served, investment costs (construction, operation and maintenance), land requirements, ease of operation and maintenance, energy requirements, sludge generated, as well as disturbances and profits generated in addition to the previous aspects. |
