The normal reading of RO pressure for saltwater is:

The normal reading of reverse osmosis (RO) pressure for saltwater is typically around 960 psi. This pressure level is necessary to effectively push saltwater through the RO membrane, as higher pressure is required to overcome the osmotic pressure of saltwater compared to that of freshwater.

Reverse osmosis is a critical process in desalination and water treatment, aiming to separate salt and other impurities from water. Operating at around 960 psi allows the system to work efficiently, ensuring a reasonable flow rate of purified water while maximizing the rejection of salts and contaminants. It is important for maintenance personnel to understand this pressure range to ensure that the RO system functions correctly and to troubleshoot issues if the readings deviate significantly from this norm.

Knowing the correct pressure helps in monitoring the condition of the RO membranes and the overall performance of the desalination system.
