Capacitive desalination is a promising desalination technique. A novel fl ow-through electrode architecture utilizes a newly developed porous carbon material to achieve dramatic improvements in desalination rate and salt concentration reduction. Image depicts a capacitive desalination cell with a fl ow-through architecture. Capacitive desalination (CD) is a promising desalination technique as, ...

Pilot tests were performed with a process combination of electrodialysis and ozonation for the removal of micropollutants and the concentration of nutrients in urine. In continuous and batch experiments, maximum concentration factors up to 3.5 and 4.1 were obtained, respectively. The desalination capacity did not decrease significantly during continuous operation periods of several weeks. Membr...

The ‘surplus’ of oceanic water generated by climate change offers an unprecedented opportunity to tackle a number of global issues through a very pragmatic process: shifting the excess water from the oceans onto the land. Here we propose that sea-level rise could be mitigated through the desalination of very large amounts of seawater in massive desalination plants. To efficiently mitigate sea-l...

Multi-objective optimization using genetic algorithm (GA) is carried out for the desalination of brackish and sea water using spiral wound or tubular modules. A few sample optimization problems involving two and three objective functions are solved, both for the operation of an existing plant (which is almost trivial), as well as, for the design of new plants (associated with a higher degree of...

Transparent exopolymer particles (TEP) are ubiquitous in marine and freshwaters, and have been subject to intensive study by oceanographers and limnologists over the past 15 years. These microscopic organic particles (visualized by Alcian Blue staining for acid polysaccharides) may be considered a planktonic form of exopolymeric substances (EPS). Two aspects relating to the potential involvemen...

Countries which do not have adequate supply of freshwater sources like Kuwait resort to using desalination plants to meet their demand. Kuwait had used Multi-flash desalination (MSF) plants sine the 50’s of the last century to satisfy its ever increasing demand. Many new and more efficient and cost effective desalination technologies are currently available. Kuwait is in the process of building...
