The ion exchange equilibrium between an ion exchange membrane and solutions of different electrolytes was studied. The matrix of the ion exchange membrane used consists of a vinyl polychloride network reinforced by a polyester screen; with quaternary and tertiary ammonium as functional groups. The d

Tunisia, located in a semi-arid zone, has limited water resources. The shortage of good water quality in particular at the south regions required a brackish water desalination to supply these regions with potable water. Zarzis desalination plant, working since 1999, has revealed difficulties related

A desalination family prototype has been designed in a laboratory supplying good quality water for drinking and household cooking needs. The available intermittent and fluctuating energy source (solar or wind) has made us explore the coupling of such a source to a prototype that operates itself in a

In water treatment, silica is a problem because of its tendency to form deposits. It is often necessary to include reducing silica concentration to permit increased cycles of concentration without scale. The behavior of aqueous silica and the various water treatment processes used for its removal we

A thermodynamic modeling of saline waters is achieved taking into account acid-base, ion associates formation and precipitation equilibrium. A microcomputer program, written in the graphical language LabView accomplished the necessities of iteration for the solution of simultaneous equations, calcul

In several areas like water desalination and geothermal applications, the occurrence of silica in the used waters is undesirable. Many studies show the complexity and the diversity of the topic. For a better understanding of some of its analytical aspects the determination of amorphous silica conten
