Abstract: Reverse osmosis systems have recently made significant contributions to the growth of renewable filtered water sources. RAMD (reliability, availability, maintainability, and dependability) is an engineering tool for addressing operational and safety risks in systems. It seeks to identify a system's weakest areas in order to improve overall system dependability. Elaborate RAMD analysis of these systems is presented starting from the subsystem level, then the overall system. Further, an improved reliability block diagram is presented to estimate the RAMD performance of six practical reverse osmosis system. A novel approach is also presented in order to estimate the best probability subsystem. The monitoring of the critical subassemblies of reverse osmosis system will increase the possibility not only for improving the availability of the system, but also to optimise the mean time to the system failure (MTTF). It will also inform the operators about the status of the various subsystems of the system.

Keywords: reverse osmosis; reliability; availability; safety; maintainability; subsystems; dependability.
