Advantages of Polyethersulfone (PESU) membranes for pretreatment for SWRO applications
Membrane pretreatment for large-scale seawater desalination has grown rapidly in the last few years. Existing examples seem to show that the additional cost can be more than recouped in reduced chemical costs alone, but there are also environmental advantages. This article is the first of two discussing the advantages of polyethersulfone (PESU) membranes for filtration…

MEDVSA: a methodology for design of brine discharges into seawater
Desalination is increasing fast in Spain, especially on the Mediterranean coast. The brine generated in the process is discharged into the sea, producing a negative impact on the endemic and stenohaline marine ecosystems, for instance, the Posidonia oceanica and Cymodocea nodosa meadows. MEDVSA is an R&D project, subsidized by the Spanish Ministry of the Environment…

Korea puts $170m into desalination SWRO and water reuse
The Republic of Korea has recently funded a six-year US$ 170 million research initiative in seawater desalination. Over 500 researchers from 16 universities will contribute to the work of the 50-member core team. Government leaders funded the research initiative in part due to the success of South Korean multinational firms in the desalination export sector.…

KMS supplies first large-diameter SWRO system
The port facilities for Chile’s Minera Esperanza copper/gold mine will soon be provided with drinking water from an innovative new seawater reverse-osmosis (SWRO) system supplied by Koch Membrane Systems (KMS). The system is the first full-scale large-diameter membrane RO system for seawater that KMS has developed. The system uses KMS MegaMagnum high capacity seawater membranes,…

Tordera SWRO storage tanks built within 16 weeks
The challenge of upgrading and nearly doubling the potable water storage capacity as part of an upgrade of the Tordera seawater reverse-osmosis desalination plant in Blanes (Girona) near Barcelona, Spain, within a rigorous timeframe, was awarded to CST Vulcan, a division of CST Industries Inc. Using a specialised jacking system, allowing the tanks to be…
