The Affordable Desalination Collaboration (ADC) has completed a major milestone in its test program that profiles the state-of-the-art performance for seawater reverse-osmosis (SWRO) technology. This testing ran over two years and involved operating seven sets of standard 8-in diameter membranes in seven-element pressure-vessels. The ADC demonstration plant was designed to produce between 48,100 to 75,600…

NanoH2O advanced membranes for reverse osmosis (RO) desalination represent a new material that enhances current polymer-based membranes with the benefits of nanotechnology. These nanocomposite RO membranes represent a step-change in productivity through improved permeability while maintaining requisite salt and contaminant rejection. Since the original publication of this concept, further development and optimization of this membrane…

Should we build any more MSF plants?

—

by

Multi-stage flash (MSF) evaporator technology was for a long time the most popular technology for large seawater desalination plants. However, MSF has had to face strong competitors in recent years. Reverse osmosis (RO) and multi-effect distillation (MED) are squeezing MSF out of the market. Is there really a future for MSF? This article looks at…

Depth Exposed Membrane for Water Extraction (DEMWAX™)

DXV Water Technologies has designed a novel membrane system that uses natural pressure, a very low recovery rate and gravity flow of feedwater past the membrane surface, resulting in an elegant, efficient system. Since the invention of the reverse-osmosis (RO) membrane researchers have tried to harness natural water-pressure, but past attempts mimic onshore processes with…

Carlsbad project plan for green SWRO

—

by

The largest and most advanced seawater desalination project under development in the USA today is the 189,000 m&sup3/d plant in Carlsbad in southern California. This project is collocated with the Encina coastal power generation station, which currently uses seawater for once-through cooling. The Carlsbad seawater desalination project is developed as a public-private partnership between Poseidon…
