What is the role of the RO pump in the system?

The role of the reverse osmosis (RO) pump in the system is to raise pressure across the RO membrane. In hemodialysis, reverse osmosis is employed to purify water used for dialysis, ensuring it is free from impurities and contaminants. The process of reverse osmosis relies on applying pressure to push water through a semi-permeable membrane, which separates impurities from the clean water intended for use in dialysis.

By increasing the pressure, the RO pump effectively enables the movement of water through the membrane, facilitating the filtration and purification process. This is essential for producing the high-quality water necessary for safe and effective dialysis treatments, as inadequate pressure would lead to inefficient filtration and the potential for contaminated water being used in the dialysis process.
