Economics of seawater desalination in Cyprus
… continue farming citrus. To do so means building seawater desalination plants that contribute 5.0 to 6.0 kg of CO 2, a greenhouse gas, to the atmosphere per m3 of water produced by desalination, along with the cost of the water nearing one US dollar per m3 . Desalination is a painful solution to …

Effects of Bloom-Forming Algae on Fouling of Integrated Membrane Systems in Seawater Desalination
Hydrodynamic shear applied to algal cells was detrimental to low-pressure filtration because of the release of highly-fouling organic matter. The highly fouling fraction was material large enough to be retained on a 0.22-microm microfilter but small enough that it was not removed by centrifugation …
