DOI: https://doi.org/The hospital’s wastewater recycling system is not functioning properly, and errors in the water mass balance calculation have been identified, which affect efforts to minimize environmental pollution. Therefore, an evaluation of the Wastewater Treatment Plant (WWTP/IPAL) was conducted. The purpose of this study is to assess the hospital’s WWTP and propose recommendations to optimize its performance in treating wastewater. The evaluation was carried out with reference to design criteria and quality standards, supported by a literature review using PICO analysis, as well as an assessment of existing conditions based on primary and secondary data. The evaluation results show that the hospital’s wastewater discharge reached 166.3 m³/day, with treatment efficiency categorized as very efficient and efficient for several pollutant parameters, indicating that the treatment process generally functioned well. However, some components including equalization tanks, the first and second settling tanks, activated sludge, trickling filter, filtration, disinfection, and recycling did not meet design standards, requiring recalculations. To address these shortcomings, the study suggests stricter monitoring and testing of effluent quality by improving sampling methods, re-measuring influent wastewater characteristics, and ensuring the WWTP operates in accordance with Standard Operating Procedures (SOP). Overall, based on water quality tests and performance analysis, the WWTP demonstrated high degradation efficiency of wastewater parameters (ranging from very effective to moderately effective), with all tested parameters meeting the applicable quality standards.
