Abstract In recent years, the increasing threat to ground water quality due to human activities has become a matter of great concern. The ground water quality problems present today are caused by contamination and by over exploitation or by combination of both. Reverse osmosis (RO) desalination is one of the main technologies for producing fresh water from sea water and brackish ground water. Algeria is one of the countries which suffer from the water shortage since many years, so desalination technology becomes inevitable solution to this matter. In this study, a comparison is provided of results of reverse osmosis desalination for three different qualities of brackish water from the central-east region of Algeria (Bouira and Setif Prefectures), wherein they cannot use it as human drinking or in irrigation systems. The main objective of our study is to establish a comparison of the reverse osmosis membrane TW30-2540 performances in the term of (permeate flow, recovery rate, permeate total dissolved solids – TDS and salts rejection) under different operation pressures (each one takes a time of 720 second for pilot scaling). In order to make an overview comparison between the experimental and the simulated results we used ROSA (Reverse Osmosis System Analysis) software. At the end of this study we noted that, the simulated results are lower than the pilot scaling values and the most removed salts are the sodium chlorides with 99.05% of rejection rate.

Sea water intrusion in ground water sources has made brackish water desalination a necessity in Oman. The application of capacitive deionization (CDI) for the deionization of ground water samples from wells in Al-Musanaah Wilayat is proposed and demonstrated. A CDI cell is fabricated using nanoporous activated carbon cloth (ACC) as the electrodes and is shown to be power efficient for desalting ground water samples with total dissolved solids (TDS) of up to 4,000 mg/l. The CDI cell was able to remove up to 73% of the ionic scaling and fouling contaminants from brackish water samples. The power consumption for deionization of brackish water was estimated to be 1 kWh/m3 of desalinated water, which is much lower than the power required to process water with equivalent TDS by the reverse osmosis processes. The CDI process is elaborated, and observations and analysis of the ion adsorption characteristics and electrical properties of the capacitive cell are elucidated.

The sustainability concept is emerged to maintain and strengthen “the ability of future generations to meet their own needs”. The adaptive capacities of the world population can be strengthened by eradication of poverty and provision of healthy living conditions which takes the priority. This can be achieved by provision of education and basic infrastructure to the people, worldwide. Availability of high quality drinking water and assurance of hygienic safety is one of the most basic needs of any community, and subsequently a precondition of sustainable development of rural or municipal areas. Decentralized water management should be seriously taken into account in the present scenario of extremely varying climatic changes affecting the potential water resources of the world. Also the energy requirement of centralized water supply schemes is fueling the energy scarcity. Therefore, effective utilization of ground water resources can be the intelligent step the towards achieving sustainable living conditions. Additionally, the water demand in the agricultural industry has become an important concern, considering that more than 70% of freshwater is used for crop irrigation. Desalination is considered a promising solution for water production challenges, but the sustainability of the same needs a detailed study. The treatment of waste water is another necessary criteria to satisfy the basic demands of good quality water for human life and industrial use. In the present review, different methods of water treatment technologies are studied, to assess their contribution towards sustainable development. Water treatment technologies for drinking purpose, waste water purification and desalination were deliberated and the effectiveness of each in attaining sustainable habitat has been portrayed in this review. It was observed that sustainable technologies for water treatment can be a better solution to face the water scarcity challenges in the world as they are self-reliable while compared to other methods.

India is a developing nation and is dependent on its natural resources for growth and development. Water, being one of the vital natural resource, must be used judicially for the sustainable development. Present study focuses on the analysis of physicochemical parameters (pH, Turbidity, Alkalinity, Total Hardness, Total dissolved solids, Conductivity, Chloride, Sulfate, Fluoride contents) of ground water and surface water in Kota City (Rajasthan). The study shows the adverse impact of exploitation and urbanization on water resources of Kota City (Rajasthan). Some physicochemical parameters exceed the desirable limits as defined by WHO and Indian Standards in the selected sites. The level of pollution in ground water and surface water of Kota City is increasing due to urbanization.
