Abstract

Mandau Regional General Hospital (RSUD Mandau) is a type C hospital owned by the Bengkalis Regency Government and generates wastewater from both medical and non-medical activities. To control environmental pollution, the hospital is equipped with a Wastewater Treatment Plant (WWTP). This study aims to analyze the performance and effectiveness of the WWTP system based on clean water demand, wastewater discharge, and retention time in each treatment unit. The research was conducted using a qualitative descriptive method through a case study approach. According to the Indonesian Ministry of Health Regulation No. 7 of 2019, a type C hospital requires 300 liters of clean water per bed per day. RSUD Mandau records a clean water usage of 76.1 m³/day, with an estimated wastewater volume of 60.88 m³/day (80% of the total clean water usage). The analysis results show that the retention time in several WWTP units varies between 5 to 22 hours. However, some units such as the Equalization Tank and Anaerobic Biofilter do not meet the recommended retention time standards (4–8 hours and 4 hours, respectively), which affects the effectiveness of the wastewater treatment process. From the study, it can be concluded that although RSUD Mandau has implemented a WWTP system based on physical, chemical, and biological processes, the treatment effectiveness in several units is still suboptimal. Therefore, periodic evaluations and adjustments to capacity and retention time are necessary to improve the overall performance efficiency of the WWTP.
