The Javea desalination plant on the Mediterranean coast of Spain, currently has a production capacity of 28,000 m3/d of desalinated water and in the coming years that capacity will rise to 42,000 m3/d. From a technical point of view, the design of the plant is conventional, however the method of bri

Over the years the phenomenon of salinization of the soil has become a major problem in areas of low precipitation. For example, in the South-Western area of Israel there are areas of land with high salinity as well as increase of the salinity in the upper layer of underground water. The solution th

Since environmental impacts of desalination processes are intrinsically related to system efficiency, per water-unit produced loads have constantly decreased over the past decades. However, some significant fouls remain. The example of Spain is punctually used throughout this paper, to illustrate th

Water desalination processes have contributed to a better standard of living in a number of countries during the second half of the 20th century, following an increase in water demand for drinking purposes as well as industrial and agricultural uses. However, the technologies used in water desalinat

In view of the present interest on grey water reuse, this paper describes the residual chlorine decay in grey water chlorinated samples. Several theoretical models were compared, resulting in a parallel first-order model with four adjustable parameters, which showed satisfactory adjustment to experi

T reatment of sewage plant effluent by simple nanofiitration seems to be limited by organic fouling and only possible with extensive chemical cleaning. ............................................................................................................................

M odified and unmodified membrane samples w ere taken from different pilot-scale membrane plants after a sufficient operation period. One of t he plants is installed at a municipal drinking water t reatment plant, the second, a MBR, is located at a municipal wastewater treatment plant. The membrane

A n ew process was applied for treating e ffluent from the Apeldoom WWTP: adsorptive f iltration followed by NF (the ANF process). This p rocess has several advantages: • h igher fluxes (30 1/m2.h instead o f 102 0 l/mZ.h) at low TMPs; • h igh recovery (>94%) without scaling; • l ow brine production
