Course Overview

The desalination technology known as Reverse Osmosis (abbreviated as RO) is widely used for recycling, water treatment such as seawater desalination and wastewater treatment, and manufacturing processes across a wide range of industries. Compared to ion exchange and thermal desalination, RO offers a number of benefits for water desalination. As water recycling becomes more the standard in many industries, the impacts of climate change force many countries to look for alternative technologies for the production of potable water, and the economics of the green Hydrogen industry becomes more viable, it is likely that RO technology will play an increasingly prominent role in water treatment.

The focus of this course is to provide an introduction to basic RO principles. You will cover what Reverse Osmosis is, what RO membranes are made of, how they work, as well as the principles of design, operation, maintenance and applications of RO Systems. This course also sheds light on the industries where RO technology can be utilised and the importance of RO technology to companies, industries and the wider economy.
