A 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 کاملNonlinear shallow - water solutions using the weak temperature gradient approximation
A form of the weak temperature gradient (WTG) approximation, in which the temperature tendency and advection terms are neglected in the temperature equation so that the equation reduces to a diagnostic balance between heating and vertical motion, is applied to a two-dimensional nonlinear shallow-water model with the heating (mass source) parameterized as a Newtonian relaxation on the temperatur...
متن کاملDesalination 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 کاملElectrochemical Desalination for a Sustainable Water Future
Fresh water is required to sustain life. However, the world is facing a global challenge to reliably supply its population with safe water due to shortages stemming from population growth, climate change, contamination of available fresh water supplies, and public policy. Presently, the United Nations estimates that one third of the world’s population ( 2.4 billion people) is living in water-st...
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...
