  • Brackish groundwater desalination on the rise

    Brackish water is water that is more saline than fresh. It’s not quite as saline as seawater, but it’s still too salty to be used without treatment. Typically, advanced treatment technologies — reverse osmosis and ultrafiltration, as well as other membrane-based technologies — are needed to purify and desalinate brackish groundwater before its use. Brackish groundwater ...

  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • Report: California’s Reliance on brackish water desalination to increase

    Years of drought in California may result in the state becoming more reliant on brackish water desalination, according to the Pacific Institute. In “The Cost of Alternative Water Supply and Efficiency Options in California,” the Oakland-based nonprofit research institute looks at the costs of potential water supply sources and other economic factors. The institute states: ...

  • The effect of intermittent operation on a wind-powered membrane system for brackish water desalination

    Renewable energy powered membrane systems that are directly-connected must take account of both the inherent fluctuations and the intermittency of the energy resource. In order to determine the effect of intermittent operation, a membrane system was tested with variables of (i) amplitude from 60 to 300 W and (ii) length of time with no power from 0.5 to 3 min. This was performed over one hour ...

  • Energy evaluation and treatment efficiency of vacuum membrane distillation for brackish water desalination

    Strict environmental regulations have led to the rapid development of membrane separation technologies for the production of potable water, for industrial water supply, and for the reuse and discharge of treated wastewater. Promotion of water recycling and the provision of potable water from brackish water prevent significant negative effects on the environment and drinking water supplies. This ...

  • Desalination of brackish groundwater by direct contact membrane distillation

    The direct contact membrane distillation (DCMD) applied for desalination of brackish groundwater with self-made polyvinylidene fluoride (PVDF) membranes was presented in the paper. The PVDF membrane exhibited high rejection of non-volatile inorganic salt solutes and a maximum permeate flux 24.5 kg m−2 h−1 was obtained with feed temperature at 70°C. The DCMD experimental results indicated that the ...

  • Greenhouse based desalination for brackish water management using bittern evaporative cooling technique

    The Arab region is characterized by arid and semi-arid conditions with very limited renewable water resources. Most of the surface water comes from transboundary streams and most of the groundwater resources are fossil in nature. Water quality degradation and excessive use of pesticides and herbicides in agriculture pose severe environmental and health risks. The underlying research is a joint ...

  • Application of high flux brackish water thin film composite membranes in the desalination of highly saline ground water

    The improvements in flux and membrane designs have enabled us to install smaller and economical two-stage reverse osmosis systems suitable for small village communities situated near coastal areas to provide safe drinking water. In addition, the advent of higher productivity and better salt rejection membranes has allowed us to operate the systems at low pressure in both stages. Our two-stage ...

  • Brackish water desalination using electrodialysis: predictive mass transfer and concentration distribution model along the electrodialyzer

    This study employs theory and experimental data from a laboratory-scale electrodialyzer to predict sodium chloride (NaCl) mass transport and concentration distribution along the electrodialyzer as a function of feed concentration, feed flow rate, applied voltage, and pressure. Moreover, a model was developed to predict the ion removal as a function of driving forces through solving the ...
