Water desalination using membranes and harmful algal blooms

The seminar topics include theoretical and practical informations about performance and operating conditions of reverse osmosis and nanofiltration technologies for brackish and seawater desalting. A section of the seminar is dedicated to the modern microfiltration and ultrafiltration technology applied for pretreatment of seawater for RO systems.

The program includes introduction to membrane technology, description of commercial membrane elements, water composition and quality variations (seawater, brackish water) i.e. harmful algal bloom (HAB), illustration of the membrane system design process and overview of systems operation taken everywhere in the world.

The seminar is structured in the form of five seven hour and half a day sessions of frontal presentation combined with hands-on exercises of calculations of operating parameters with visiting tour of microalgae culture platform and experiments at different scales on bench scale laboratory pilots. A section is dedicated to computer simulation of RO/NF operations illustrated by real plants in the world with an example of the soft ROSA. A section is dedicated to membrane autopsy as a decision aid for a better management of RO process and another one on how to manage old RO membrane.

Organized by GEPEA, with the cooperation of Degremont, Veolia, LANXESS, Technolia, IFREMER CNRS and in collaboration with the European Desalination Society (EDS)
