The critical factor for the implementation of wastewater reclamation, Explanatory finding for Agro-Industrial analysis in Thailand.

Abstract

This study aimed to explore the current perspective of the Thailand industry on wastewater reclamation technologies. The research focused on identifying the criteria that influence the decision-making process for implementing these technologies. Quantitative research was conducted using non-probability purposive sampling techniques to select a specific sample group consisting of individuals with knowledge and/or experience in wastewater reclamation technologies. The researchers collected at least 100 questionnaires from the selected respondents to ensure effective data gathering. The AHP-OS (Analytical Hierarchy Process-Online Survey) was utilized to evaluate the importance weight of each criterion based on the collected data. Pearson correlation analysis was also performed to examine the relationships between variables. The evaluation results showed a strong consensus among participants. Pairwise comparison values indicated the relative importance and preference of each criterion within their respective categories, aiding in decision assessment and prioritization. The Pearson correlation coefficients revealed trade-offs or conflicts between certain criteria. Further analysis demonstrated that water quality had a moderate negative correlation with reliability, ease of construction and deployment, ease of operation and maintenance, and capacity. Reliability exhibited a weak negative correlation with water quality, ease of operation and maintenance, and capacity. Ease of construction and deployment, ease of operation and maintenance, and capacity displayed weak correlations with other criteria. Corporate responsibility did not show significant correlations with any other criteria. In terms of environmental sub-criteria, the consolidated decision matrix indicated that "Environmental impacts" was slightly more important than "Safety Risk".
