Abstract

This research aims to establish a preventive maintenance system for a reverse osmosis system in a case study. The objectives are to elevate standards and increase machine availability to 100% from the previous 87.5%. Prior to the implementation of the preventive maintenance system, maintenance was conducted in a "repair when broken" manner, lacking a proactive maintenance plan. This made the machinery susceptible to disruptions, impacting the pure water production process essential for electricity generation. Following the implementation of the preventive maintenance system for a period of 3 months (November 2024 - January 2025), the Machine Availability Factor (MAF) increased 100%. This enabled maintenance personnel to operate according to standards, inspect, analyze, and prevent issues before damage occurred. The digital format of the developed system reduces paper usage and allows for its application to other systems within the organization in the future. Additionally, it helps maintain electricity generation revenue valued at 7.8 million baht per day and reduces the cost of renting pure water production equipment by 12 million baht per year if the system was shut down or the machine was broken.
