Throughout the world, water scarcity is being recognised as a present or future threat to human activity and as a consequence, a definite trend to develop alternative water resources such as desalination can be observed. The most commonly used desalination technologies are reverse osmosis (RO) and t

Comparison between theoretical and experimental analysis of a mini solar pond assisted solar still is presented in this paper. In a mini solar pond, experiments were conducted for different salinity. It was found that the optimum value of salinity in the mini solar pond is 80 g/kg of water. Effect o

Increased water demand due to economic growth, irrigation needs, declining precipitation levels and overabstraction of groundwater are all factors that create fresh water shortage problems in the Aegean Archipelago islands. In order to face pressing needs, water is transported by ships from the main

This paper presents a numerical analysis to investigate the effect of the vertical flat plate external reflector on the distillate productivity of the tilted wick solar still. We propose a geometrical method to calculate the solar radiation reflected by the external reflector and absorbed on the eva

The generation of hydrogen peroxide and the decomposition of free cyanide by ultrasonic waves were studied and the statistical analysis of the results for significance was performed using Ergun’s test (essentially One-way Analysis of Variance (ANOVA) for gradients). Effects of the ultrasonic intensi

This paper deals with a simple method of preparing cationic resins (CRs) from polycondensation of sulphonated Eugenia jambolana, Lam carbon (SEJC) with phenol-formaldehyde resin (PFR) as a cross linking agent. A few composite ion exchangers were prepared by varying the amount of SEJC in the blends f

Water security depends on the availability of enough water to meet the demand of all consumption sectors at all times. These conditions are hardly met in water rich countries, as the hydrological cycle is not fully reliable. In arid countries, such as Kuwait, where there is no enough natural fresh w

The corrosion of mild steel in marine environments was studied with respect to induced alternating current (AC), direct current (DC) and the superimposed AC+DC sources. Corrosion rate determination at the different applied AC, DC and AC+DC current densities was carried out by conventional weight los

To reuse pretreated water effluent of the El-Nile Company for the food industry in Egypt, NF and RO membrane separation techniques were investigated. Two sets of experiments were carried out by using laboratory separation unit with maximum pressure of 7 bars and pilot plant membrane separation unit

In this study we introduce a new idea of utilizing algorithms from the Computational Intelligence community in building accurate models for saline water evaporation rates. Three experimental methods were used to measure the evaporation rate for different brine concentrations, different water and air
