Nanofiltration and Reverse Osmosis in Water Treatment

TU Delft Nanofiltration and Reverse osmosis

Target Audience

This course is primarily geared towards working professionals.

Expected prior knowledge: Basic knowledge of chemistry, math and physic. High school level.


Membrane filtration using reverse osmosis is a technology that is increasingly being used in many water related organizations. Did you know for instance that reverse osmosis is now the most important technology for making fresh water out of seawater? For anyone interested in the fascinating world of membrane technology in drinking water production and industrial water treatment, this course will provide you with the fundamental knowledge to better understand the process and its applications. Your dependence on external advisors will be reduced and your ability to make decisions regarding investment and maintenance within the organization will be greatly enhanced.

Learning Objectives

By the end of this course, you will be able to:

Recognize and classify different types of membranes
Calculate the mass balances, recovery, rejection, pressure and water quality in a reverse osmosis (RO) installation
Describe the rejection mechanism of ions and organic compounds in the membrane system
Explain the advantages and disadvantages of the application of RO
Explain different application of RO membranes (seawater, brackish water and freshwater)
Explain different water flows and their routing in a membrane module
Explain the particulate and biological fouling in the membrane
Explain the concentration polarization mechanism and scaling problem
Calculate an RO unit and design a treatment plant including the RO unit as the heart (seawater, brackish or freshwater)
