Development the efficiency of hospital wastewater treatment system in Sisaket province

Abstract

This study aimed to study the situation of hospital wastewater treatment systems management, development and efficiency evaluation of hospital wastewater treatment systems in Sisaket Province. It was an action research using the PAOR cycle. The study population consisted of 60 hospital wastewater treatment systems administrators and 22 hospital wastewater treatment systems under the Sisaket Province Public Health Office. Data were collected by questionnaire. The statistics used were descriptive statistics, including numbers, frequencies, percentages, means, standard deviation, maximum and minimum values, and inferential statistics, including paired samples t-test. The study period was from June to September 2025.

The results found that most hospital wastewater treatment systems were wetlands (27.30%). Most of the responsible persons were male (71.70%). 80.00% had received training. After the development, it was found that 100.00% of the personnel in charge completed the training. The wastewater management score according to the sewage control standards increased from 8.27 to 10.41, a statistically significant increase (p<.001). Furthermore, a comparison of the wastewater analysis results before and after the improvement showed an average score of 8.14 and 9.68, respectively. A statistical test revealed a statistically significant difference. This study found that there are still problems in the wastewater collection system. These problems should be proposed to the management for improving the system structure, and monitoring of total dissolved solids (TDS) should be performed. This study took a short time, which may result in the incomplete and incomplete coverage of all issues in the improvement of the hospital wastewater treatment system in Sisaket Province. Continuous research and development should be conducted to enhance efficiency of the hospital wastewater treatment system in Sisaket Province on a continuous and sustainable basis.
