The Importance of Water Pressure to an RO System

Reverse osmosis (RO) is a water purification system that offers competitive costs, measurable results and easy maintenance. However, this investment will not pay off if you do not set the correct RO system water pressure. Your entire RO system depends on the correct water pressure to be effective, and you cannot overlook its importance. Here are four reasons you need to set the correct water pressure if you use reverse osmosis at your business or medical facility:

  • Better purification: Reverse osmosis systems include a high-pressure pump, motor, housing and membranes. They work by forcing water through the membrane for purification and flushing the solids away. Water pressure is essential for completing this function; without the correct pressure, water either does not make it through the membrane, or the membranes do not catch the solids. Either way, you do not enjoy the same water purity you would reach with good water pressure.
  • Improved production: The correct RO system water pressure moves more water and filters out more solids. If you do not set it correctly, you will not filter water as quickly and have pure water available for your applications. You will see the difference in your production, research results and bottom line.
  • Wear and tear: Low water pressure results in premature membrane fouling. When it works correctly, the membrane catches the solids, and the high-pressure water sends them to drain into the waste stream. Otherwise, the solids accumulate on the membranes and reduce their effectiveness. Eventually, it wears them out completely. An RO system with the wrong water pressure often requires more maintenance and cleaning than one set to the correct pressure. If you find your system faces constant repair and maintenance issues, check your water pressure.
  • Self-cleaning: Your RO system is self-cleaning if you keep your water pressure set right. The process pushes water through the membranes, catches solids and sends them away. You do not have to worry about cleaning membranes just to keep your water pure. However, if there is low pressure and buildup, you end up with a foul membrane that could compromise water purity. Rather than risk this scenario, check your water pressure frequently to keep it in the right setting.

Ideally, your water pressure should be set at 60 PSI. If lower than 40 PSI, you render your RO system ineffective and face water purity and system maintenance issues. If you face constant low pressure, it is likely time to replace or upgrade your RO system. Depending on your system, you may need to install a pressure booster pump or assess whether the system meets your needs.
