Product Description

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.


XST will design the full Reverse osmosis water treatment plant according to your feed water quality and product requirements. Passes and Stages will be applied when needed. XST will provides sustainable and complete solutions with RO technology, integrating it with the pre-treatment and post treatment necessary.

Main Process of Double Pass Reverse Osmosis Water System


8m³/Hr Double Pass Reverse Osmosis Drinking Water Filter System 3

Main Process Function
1. Raw water pump provide the pressure to silica sand filter/active carbon filter
2. Quartz Sand filter get rid of turbidity, suspended matter, organic matter, colloid and so on
3. Active Carbon filter Remove the color, free chloride, organic matter, harmful matter and so on
4, Softener or antiscale dosing system reduce the hardness of water
4. Micron filter prevent any deposition of large Particles, most of the bacteria, and viruses into the RO membrane, The accuracy is 5um, for holding back any large particulates such as large iron, dust, suspended matter, impurity.
5. High pressure pump Provide the high pressure to RO membrane(at least 2.0 Mpa).
6. Two stage RO system RO system is the main part of pure water treatment plant. The RO membrane's desalt rate can reach as high as 99%, it is capable of removing over 99% of ions, bacteria, particles and 98% of impurity.
7. EDI system make the electrical conductivity reduce to 0.1 m/cm by ion exchange.
8. Electrical control system PLC, touch screen
