Customized Measurable Availability Framework of Sewage Treatment Plant Through Risk Priority Number

This study presents a robust framework for improving Sewage Treatment Plant (STP) operations using a Risk Priority Number (RPN) approach, integrated with an action plan to address the complexities involved in managing STPs. A study was conducted on 30 MLD STP plant focusing on quantitative assessments for metrological enhancement of reliability and efficiency of components. 37 critical components and implementable actionable solutions that significantly enhance the plants’ performance are identified. The study demonstrated the average improvement of 61.1% in the availability of STP operations. The mathematical modeling, accurate measurements provided by metrology and quality related issues like FMEA, offer valuable insights into the optimization of STP operations, ensuring sustainable and economical viable wastewater management solutions. Additionally, the research framework confirms that the treated water quality complies with regulatory standards, including turbidity and contamination levels.
