“…The northern coastal regions of the country are more densely populated; nearly 90% of the population lives in urban areas which represent 10% of the country's area (Sadi 2004). Algeria lies below the desirable resource threshold of 1000 m 3 /year per inhabitant (Iglesias et al 2006a); it is ranked sixth among countries suffering most severely from water shortage, and it will jump to fourth place by the year 2025 if no suitable alternative solution to the water shortage problem is adopted (Mitiche et al 2010).…”

The present paper aims at determining the status and trends of groundwater quality of 12 aquifers situated in Northwestern Algeria, especially under conditions of last drought that has affected the region using water quality index (WQI) over a period of 4 years. Multivariate statistical methods have been used jointly with conventional graphical methods, to classify the samples according to plausible levels of groundwater evolution. The computed WQI values range from 67 to 588 and therefore can be categorized into four categories: "good water" to "water unsuitable for drinking." Overall, 36% of groundwater sites sampled in the study area had good water quality, while 53% were poor. Unfortunately, 6% of the samples indicate "very poor water quality" and 5% represent water "unsuitable for drinking purposes." Results show that the majority of groundwater of Tafna basin fell under good water quality. Groundwater of poor and medium quality characterizes the majority of the studied aquifers of Macta basin. The result showed that the water quality at monitoring station "Ain Skhouna" fell under good water quality (Chott Chergui aquifer). Results also show that groundwater of Coastal Oranais basin showed poor water quality, very poor at some monitoring stations of Mléta Plain aquifer. It has been demonstrated that the water of some aquifers has degraded under water scarcity conditions and will continue to degrade given the ongoing and projected development in the study area. The analysis reveals that the water of some aquifers needs treatment before it is used for human consumption. The influence of salt water on the some freshwater aquifers in the study area needs special attention in terms of monitoring and for sustainable management.

“…Also, a higher salt concentration in the feed stream increases the osmotic pressure, reducing the net driving pressure and consequently reducing the product water flow rate according to Eq. (13). For specific given conditions, the maximum product flow rate which can be predicted is 216.43 m 3 /h (Q f = 360.71 m 3 /h).…”

“…A RO desalination system powered by a stand-alone WT of 1 MW rated power was proposed to supply fresh water to the rural world of three potentially high-wind sites in the southwest of Algeria [13], namely Adrar, Timimoun, and Tindouf. A mathematical model based on the solution-diffusion theory and multiple fouling mechanisms was developed to simulate the process under steady-state conditions.…”

A B S T R A C TWater desalination is one of the most important factors that can help in developing remote areas and the desert. A critical technical parameter of desalination applications is the way the system is powered. This decision is taken according to the selected method of desalination and the characteristics of the candidate area. Nowadays, the method of reverse osmosis dominates globally; it requires only electricity, has a quite low specific energy demand, and can cooperate with technologies of renewable energy sources such as wind turbine and photovoltaics. Hence, renewable energy-powered reverse osmosis systems are promising technologies for brackish and seawater desalination in remote regions as they exhibit low energy consumption and can be designed according to water demand and energy resource. This study analyzes the feasibility of using wind energy to power brackish water reverse osmosis desalination units proposed for the development of the southern region of the case study country of Algeria. A reverse osmosis desalination scheme powered by a stand-alone wind turbine of 1 MW rated power is presented to elucidate its feasibility. The modeling results show that at average wind speeds, the amount of product water is sufficient to meet freshwater demand in this region. The effect of different operating and design conditions on the purified water production rate was investigated. The paper is concluded with the economic feasibility of wind-desalination systems at the selected sites.

In this paper the environmental impacts of seawater desalination is investigated and highlighted. Indeed despite the various benefits of desalination there is growing apprehension about the potential negative environmental effects it may bring and generate. Both during the plant construction and its operation service. There is the possibility of leading and causing adverse environmental impacts. A significant concern with desalination is the co-produced and generated waste known as 'brine' or 'reject,' which contains high salinity as well as chemical residuals which are released into the marine environment. Viable and cost-effective brine management systems are necessary to mitigate the negative impact of brine, also referred to as concentrate, which is a by-product of the desalination process. This high salinity substance poses a threat to the environment and must be managed effectively in order to reduce pollution. Aside from brine other difficulties include marine species entrainment and trapping, as well as high chemical use. This paper provides an extensive overview and evaluation of desalination technologies used in Algeria including thermal methods such as Multi-Stage Flash (MSF) and Multiple Effect Distillation (MED) as well as Membrane Reverse Osmosis (RO). Furthermore in order to assess the potential environmental implications of desalination and brine treatment on the Algerian coast, mitigation strategies are proposed to curb the environmental negative impact. To protect water resources for present and future generations, improved brine management techniques are needed to minimize adverse environmental effects and lower the financial burden of disposal. This will encourage further advancements in desalination plants. Ultimately, the paper emphasizes upcoming research opportunities in brine treatment technologies with a focus on improving the efficiency and sustainability of desalination.
