Evaluasi Dan Redesain Instalasi Pengolahan Air Limbah (Ipal) Rumah Sakit X Pekanbaru
Hospital wastewater is one of the sources of pollutants that can endanger environmental and public health due to the presence of toxic substances and compounds in it. Therefore, it is necessary for hospitals to build Wastewater Treatment Plants (WWTP) considering the adverse effects caused by the wastewater. This study aims to evaluate and redesign the WWTP at Hospital X in Pekanbaru City, adhering to wastewater quality standards for healthcare facilities and design criteria for treatment units. The assessment identifies weaknesses in the current WWTP with a biological unit of an aeration basin, including effluent values exceeding quality standards and a mismatch in unit capacity with design criteria. The redesign involves increasing treatment discharge, recalculating units based on design criteria, and incorporating an anaerobic process into an anaerobic-aerobic biofilter. The application of anaerobic-aerobic biofilter technology proves effective in enhancing effluent water quality and reducing operational costs. The redesigned WWTP with a discharge of 99.8 m3/day includes components such as an equalization basin, primary sedimentation basin, anaerobic biofilter basin, aerobic biofilter basin, secondary sedimentation basin, disinfection unit, final collection basin I, final collection basin II, and septic tank, with the total volume of 185.45 m3. The estimated construction cost of the redesigned WWTP is Rp 839.406.792,00. This study emphasizes the importance of effective wastewater management in healthcare facilities and demonstrates how the proposed redesign addresses identified shortcomings, contributing to improved environmental sustainability and operational efficiency in the hospital setting.
