More and more SWRO plants running parallel trains Danfoss RO Solutions, Netherlands Two articles on the same theme: are we about to see a move away from large high-pressure centrifugal pumps for RO desalination in favour of multiple modules with smaller pumps? The first reviews modular positive-displacement waterlubricated axial-piston pump systems, revealing that this new concept is not only a cost-effective alternative to traditional pump systems, but that it is simpler to operate and brings other advantages during the SWRO facility operating period. This is a shortened and updated version of a paper presented at the International Desalination Association’s 2013 World Congress in Tianjin, China. The second article reports that more and more small and medium-sized SWRO plants – even containerized solutions – are specifying multiple trains.
