Membranes and desalination: technologies and trends / Inge Genné (VITO)
Desalination is one of the high priority research areas linked to the advanced treatment of water, process and waste streams. Priority R&D objectives are the reduction of the energy use, the minimization of environmental impact (zero discharge) and the increase of membrane operation reliability. This presentation gives an overview of available and emerging membrane-based desalination technologies and their application possibilities for treatment of industrial streams, water loop closure, salt gradient power and hybrid processing.

Electrodialysis : part of the solution to treat inorganic concentrates? / Prof.Luc Pinoy (Labo Chemtech, KaHo Sint-Lieven)
During the past 30 years, e.g., reverse osmosis (RO) is increasingly used in seawater and brackish water desalination, water treatment and wastewater reclamation due to the superb and stable quality of the water produced and the relatively low cost. However, RO concentrate (or brine) is generated simultaneously with the filtrate, which may contain moderate to high concentrations of inorganic and/or organic compounds. Further treatment of these (and other) concentrates is necessary. During the presentation, several options/cases will be presented in order to illustrate the pro’s and contra’s of the use of electrodialysis (with or without bipolar membranes) in order to treat or to facilitate further treatment of these streams.

Capacitive Deionization / Maarten Van Raemdonck (Voltea)
Capacitive Deionization (CapDI in short) is a unique and simple way to obtain clean, desalinated water with low energy consumption, no added chemicals and a high water recovery rate. This platform technology has numerous applications, from water softening in domestic appliances to treatment of water used in industrial processes. A general overview will be given on the concept and application of CapDI in industrial systems, and the possibilities to use CapDI for inorganic concentrates.
