Desalination and Water Treatment
Electrochemical characteristic parameters such as diffusional permeability, ion transport number, fi xed charge concentration and electrical resistance for a regenerated cellulose/polypropylene-supported membrane (RC/PP sample) in contact with NaCl solutions at different concentrations were determined. The effect of the polypropylene support on mass and charge transport was estimated by compari...
متن کاملA new method for water desalination using microbial desalination cells.
Current water desalination techniques are energy intensive and some use membranes operated at high pressures. It is shown here that water desalination can be accomplished without electrical energy input or high water pressure by using a source of organic matter as the fuel to desalinate water. A microbial fuel cell was modified by placing two membranes between the anode and cathode, creating a ...
متن کاملDesalination of water: nutritional considerations.
BACKGROUND Desalination of seawater and brackish water (mixed seawater and freshwater) provides an increasing portion of the Israeli drinking water supply. However, desalinated water contains little calcium (Ca) and magnesium (Mg), and consumers may be at risk for deficiencies of these essential minerals. OBJECTIVES To assess intakes of Mg and Ca from water, other beverages, and food in commu...
متن کاملWater desalination across nanoporous graphene.
We show that nanometer-scale pores in single-layer freestanding graphene can effectively filter NaCl salt from water. Using classical molecular dynamics, we report the desalination performance of such membranes as a function of pore size, chemical functionalization, and applied pressure. Our results indicate that the membrane's ability to prevent the salt passage depends critically on pore diam...
متن کاملWater Desalination by Membrane Distillation
Water is the most common substance in the world, however, 97% is seawater and only 3% is fresh water. The availability of water for human consumption is decreasing due to increasing the environmental pollution. According to the World Health Organisation (WHO), about 2.4 billion people do not have access to basic sanitation facilities, and more than one billion people do not have access to safe ...
