At its best, engineering changes the world for the benefit of humanity. However, there are at present significant imbalances in engineering development. In some instances, appropriate technology is available but is not being applied, such as in water treatment. In other instances, inappropriate tech

Clinoptilolite, a natural zeolite, was used for the synthesis of a high surface area clinoptilolite-iron oxide system (Clin–Fe system) to be used for the removal of Mn2+ and Zn2+ ions from drinking water samples. The new system was obtained by adding natural clinoptilolite to an iron nitrate solutio

Boron removal from aqueous solution by electrodialysis was studied as a function of solution pH, applied voltage, flow rate and initial boron concentration. TS-l-l0 electrodialysis equipment (Tokuyama) modified with rotameters was employed for experimental studies. It was obtained that the highest b

The possibility of complete fractionation of olive mill wastewater (OMW) was investigated using membrane technology. Combinations of different membrane processes were used for the fractionation of OMW into by-products that may be further developed to achieve reduction of the expenses involved. Ultra

Water, under the climatic conditions of the Earth, is found in three natural states, as a solid, as a liquid and as a gas. Since the quantities of water on the Earth’s surface are constant, at least for the last few million years, then the entire historic evolution of human society, and especially s

Data are presented on a study carried out on water analyzed with three different methods. Thus, a comparison was performed in parallel with the ISO 9308-1 reference method, stated by the European Drinking Water Directive, and two enzyme-based methods, the Colilert 18/Quanti-Tray™ and the Chromogenic

The sorption kinetic and equilibrium data obtained at different water activities allowed us to determine the water sorption isotherms and mean diffusion coefficient in the Nafion® membrane. The water sorption isotherm is reminiscent of systems in which there is water clustering at high water activit

Fresh water sources in Egypt are less than 13% of the world average per capita. To meet growing water and electricity demands, projections were made up to the year 2025 considering population growth, rise in standard of living, and development plans. A medium-sized nuclear desalination reactor was f
