- Abstract
Today, reverse osmosis (RO) is a critical technique in the production of fresh water all over the world. As a result, downtimes due to repairing operations (after breakdowns, membrane blockage, pressure losses, etc.) or preventative maintenance (cleaning of membranes, component replacements, etc.) must be kept to a minimum in duration and frequency to guarantee optimum availability. Indeed, enhancing the availability (or dependability) of the RO plant as a whole system leads to a significant decrease in operating and maintenance expenses. We look at a recursive technique for reliability, availability, maintainability, and dependability in this study (RAMD. In addition, the efficacy of a RO unit, mean time to failure (MTTF), mean time to repair (MTTR), and dependability ratio were evaluated. The primary goal is economic optimization. For the method's validation, we utilized data from a RO unit that had a repair rate and a failure rate during a one-year period. It was demonstrated that all subsystems (pretreatment, dosage, etc.) had high availability. The high-pressure pump has a somewhat lower availability. For example, 0.59113 was the lowest availability for all subsystems, and it is for the RO membrane, which is where the majority of the purifications take place. A sensitivity analysis was performed to identify the essential components for the RO plant's availability. The collected findings demonstrate that the availability, reliability, dependability, and maintainability of the high-pressure pump have a significant impact on the overall system availability. As a result, special care should be given in the selection and maintenance of the high-pressure pump.
