What is Double Pass reverse osmosis system?
A double pass Reverse Osmosis (DPRO) System is when the permeate water is fed into a second RO unit to produce more pure water. A two or double stage RO is when the concentrate or reject stream is fed into a second RO system to recover water, respectively. Reverse Osmosis Systems are designed to purify water by rejecting around 99% of Total Dissolved Solids from the feed water. Single Pass RO Systems produce product water (permeate) and reject water (concentrate) at the same time.
How does a Double Pass RO System Work?
Double Pass Reverse Osmosis Systems are composed of two RO systems (1st Pass and 2nd Pass) wherein the 1st pass has a bigger volumetric flow rate capacity than the 2nd pass. In between them, there should be a break tank where either permeate or the concentrate water of the 1st pass RO is stored and fed into the 2nd pass RO for further filtration. Pre-treatment is required to be provided for both the 1st pass and the 2nd pass RO systems if the application will be water recovery, as the quality of the concentrate water on the 1st pass should be bordering on the saturation point. On the other hand, an application might only require a 1st pass pre-treatment if it’s being used as permeate to feed the 2nd pass.
