What should be the maximum pressure of the RO pump?

The maximum pressure of the reverse osmosis (RO) pump is crucial for ensuring optimal performance of the water purification system. In seawater applications, higher pressure is necessary to overcome the osmotic pressure and effectively filter out salts and impurities.

The decision to go with the maximum of 980 psi for seawater reflects the requirements for operating under conditions that can consistently achieve maximum efficiency in removing contaminants. This pressure ensures that the membrane processes are working effectively, leading to better water quality and increased yield.

Conversely, the pressures specified for fresh water are lower since fresh water has a significantly lower osmotic pressure compared to seawater. Thus, a maximum of 550 psi for fresh water is adequate to achieve the desired filtration outcomes without risking damage to the membranes or other system components.

Choosing a pressure that exceeds necessary limits could lead to premature wear or failure of the RO system, so it’s important to align pump settings with operational needs and safety considerations. The given maximum pressures are designed to maintain a balance between efficiency and equipment integrity, directly influencing the longevity and performance of the RO system.
