Expected prior knowledge
Basic knowledge of chemistry, math and physics. Pre-university education level.
Learning Objectives
- Recognize and classify different types of membranes and 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, and explain different application of RO membranes (seawater, brackish water and freshwater).
- Explain different water flows and their routing in a membrane module, and 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).

Nano and Water
The IWA Nano and Water specialist group (SG) facilitates discussion and research on the application and implications of nanotechnology in water treatment. It aims to stimulate research and provide information on the environmental and health aspects of nanomaterials, foster knowledge exchange, promote nanotechnology development for water treatment, and monitor nanotechnology advancements in other fields. Nanomaterials offer novel solutions for contaminant removal, microbial control, and resource recovery, potentially revolutionizing water treatment. However, the group also addresses concerns regarding their potential impact on human health and the environment, advocating for responsible development and application.
Particle Separation
The Particle Separation Specialist Group (PSSG) is dedicated to advancing the science and technology related to aquatic particles in water and wastewater treatment. Specializing in solids removal, particle removal processes, particle characterization, and particle transport, the PSSG addresses critical aspects of water treatment. With a focus on the increasing importance of small particles, the group organizes specialist conferences biennially to facilitate international knowledge exchange and showcase practical examples.
