What is the pressure output of the high-pressure pump on the RO?

The high-pressure pump on a reverse osmosis (RO) system is crucial because it generates the pressure needed to push water through the semi-permeable membrane, effectively separating the impurities from the clean water. The typical pressure range for high-pressure pumps in RO applications is designed to ensure efficient filtration.

Choosing the range of 650-1050 psi indicates that this pressure level is sufficient to overcome osmotic pressure and resistance from the membrane, optimizing the water recovery process and ensuring that the system operates efficiently. This is particularly relevant in applications where water salinity levels are higher, requiring greater pressure to achieve effective purification.

The other ranges do not align with the demands of most RO systems. Lower pressures, as indicated in the first two options, would likely result in insufficient performance, leading to lower production rates and inadequate contaminant removal. Meanwhile, the highest option, 700-1000 psi, may be applicable in specific scenarios but does not encompass the operational pressure generally needed across a broader spectrum of standard RO systems. Thus, the range of 650-1050 psi captures the optimal operating conditions for high-pressure pumps in reverse osmosis technology.
