Performance evaluation of wastewater treatment plants in Taman’s public health center in Sidoarjo District

Abstract

Introduction: In general, wastewater produced by Public health centers contains many microorganisms, pathogenic compounds, and hazardous and toxic chemicals that can cause environmental pollution and transmit various diseases.1 The danger posed by the liquid waste produced is quite large, so it is necessary to have a wastewater treatment process before it is disposed of. Wastewater treatment is carried out using a wastewater treatment plant (WWTP). Thus, this study aims to evaluate the performance, environment and economy of WWTPs in Public health centers. Methods: This research uses descriptive quantitative research methods. The inclusion criteria were the laboratory data results in 2018 and 2019. The exclusion criteria were the data needed to be completed. The research variable was the performance of the WWTP on wastewater quality. The data analysis of the laboratory test results is analyzed and compared with the East Java Governor Regulation Number 72 of 2013 concerning Wastewater Quality Standards for Business and Hospital Activities. Results: The results of laboratory tests in 2018 showed the parameters by the requirements according to regulations, such as temperature, pH, BOD5, COD and TSS. At the same time, the parameters were not following requirements according to rules such as free NH3-N, PO4 and MPN-coliform bacteria. Data from laboratory test results in 2019 showed requirements according to regulations: temperature, pH, BOD5, and TSS. The effects on the COD parameter were seen only in July that they did not follow the requirements, while most of the results for the NH3-N, PO4 and MPN-free coli groups did not meet the criteria. Conclusion: Based on the research done in this study, the following conclusions can be drawn: The results of the performance evaluation of the WWTP at the Taman Public health center are included in the category that meets the stipulated regulatory requirements.
