brackish groundwater drinking water Articles
The Future of Drinking Water
Predicted future growth in population numbers and rising sea levels mean demand for drinking water will continue to increase just as the natural availability of freshwater decreases. It is likely that brackish groundwater will be an important source of drinking water in the future, but the current methods used to produce fresh water from this source are expensive in terms of their energy use and ...
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 ...
Salt Water Creeps Onto East Coast
Seawater is rapidly intruding into coastal aquifers, but alternative water sources can slow its progress On the East Coast of the United States, seawater is creeping inland, contaminating fresh water in underground aquifers. This intrusion is not uncommon. Since salt water has a higher density than fresh, it sinks to the bottom of the water table, often without affecting the fresh water above. ...
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 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 ...
Cost-Effective Solutions for Rural Water and Wastewater Treatment
With Fluence equipment and financing solutions, rural areas may update services at no upfront cost Many rural water utilities are coping with aging or inadequate water and wastewater treatment systems. At the same time, they’re searching for ways to extend wastewater services to outlying areas, and to meet the challenges of treating water for microbes, insecticides, radioactive substances, ...
