Author: Water. Desalination + reuse

—

by

With another prestigious water project opened in May in the shape of the 228,000 m /d Sembcorp NEWater Plant in Singapore, the list of references for major desalination and water reuse projects involving global engineers Black & Veatch in various capacities grows ever more quickly. John Gould, chairman of Faversham House Group and the publisher…

KMS supplies first large-diameter SWRO system

—

by

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,…

MEDVSA: a methodology for design of brine discharges into seawater

—

by

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…

Southern California study identifies brine-concentrate issues

—

by

The Southern California Regional Brine-Concentrate Management Study is a collaboration between the US Bureau of Reclamation and 14 local and state agency partners, who together form the Brine Executive Management Team. The team identified the management of brine-concentrate from desalination and other water treatment processes as significant in addressing southern California’s water supply reliability. As…

Resort uses desalination in innovative reuse project

—

by

The Cache Creek state-of-the-art water reuse project in the USA is very interesting for its use of the Vibratory Shear Enhanced Process (VSEP) for brine volume reduction. However the use of Electrodialysis Reversal (EDR) desalination prior to this process is also of interest, and the project s award from the WateReuse Association (2009 Project of…

Perth provides world desalination sustainability model

—

by

As the USA finally starts its second large SWRO plant at Carlsbad, Australia is already into a second generation, with contracts let for the Southern Seawater desalination plant, the second to serve the Perth region. The author has for many years been a strong advocate of desalination and has promoted the technology around the world.…

Boron nitride nanotube membranes outstrip carbon copies

—

by

One approach to improve the desalination process would be to design a more efficient membrane. Embedding nanotubes in the membrane is one area of research. Investigation of water transport through nanotubes in the past has primarily focused on carbon nanotubes, where the water has been found to flow extraordinarily fast in addition to rejecting salt…

Advantages of Polyethersulfone (PESU) membranes for pretreatment for SWRO applications

—

by

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…

Possibilities for energy optimisation in design and operation of SWRO plants

—

by

Seawater desalination with reverse osmosis (SWRO) has taken a noteworthy upturn during recent years. One of the reasons for the success of the membrane process is its lower energy consumption in comparison with thermal desalination processes. The high-pressure RO desalination stage is undoubtedly the dominating energy consumer of an SWRO plant. Energy consumption of SWRO,…
