Fresh Water Treatment


RWO's reverse osmosis desalination systems (SRO) are designed for independent and reliable potable and / or process water supply onboard ships and offshore facilities. 

The reverse osmosis process is ideal for fresh water or process water generation - being easy to operate, economical and producing excellent water quality. 

Seawater Reverse Osmosis-Compact 10


New standard type seawater desalination plant for service on board ships

With the SRO-COM RWO presents a new standard type seawater desalination plant for service on board ships.

A main advantage is the continued production of high quality fresh water from unpolluted seawater that is free of oil and chlorine. 

What is special about the SRO-COM is its pre-assembled skid mounted design, which is ready for installation and operations on board due to its "plug-and-play"-principle. 

This desalination plant has a stable permeate flow over the complete temperature range from 1°C - 35°C.

Advanced membrane technology

The newly developed SRO-COM seawater osmosis plant offers state-of-the-art technology by using low energy membranes.

These membranes produce the same permeate rate as conventional membranes but at a considerably lower operating pressure, which results in a lower investment for the buyer and lower energy costs.



High reliability plant control

The heart of the plants is the integrated electronic control device with a user friendly digital display. The graphic on the display shows the temperature, conductivity, operating pressure and the operating hours. 

All failure recordings including the alarm and warnings can be checked through the menu feature.

The working process

Working scheme seawater reverse osmosis

The process diagram shows the general configuration of a SRO-COM plant. 

The two-stage filter system protects the membranes from suspended particles in the feed water. If the seawater has many impurities, it is preferable to install an additional filter (such as Sand filter). Generally a booster pump is used to provide an inlet pressure of 2-4 bar. Permeate, i.e. desalinated water, passes the membranes, while the remaining seawater takes up the rejected salts and leaves the modules as concentrate back to the sea.

The reverse osmosis membranes remove salts and minerals. They also remove all kind of impurities hazardous to human health, such as viruses, bacteria, legionella - it is a safe method to produce perfect fresh water. 

The quality of the water is in accordance with European, international WHO and US Health standards.
