Membrane Desalination: Where Are We, and What Can We Learn from Fundamentals?
Although thermal desalination technology provides potable water in arid regions (e.g., Israel and the Gulf), its relatively high cost has limited application to less arid regions with large populations (e.g., California). Energy-intensive distillation is currently being replaced with less costly pressure- and electrically driven membrane-based processes. Reverse osmosis (RO) is a preferred memb...
متن کاملUse of antiscalants for mitigation of silica (SiO2) fouling and deposition: fundamentals and applications in desalination systems
Colloidal silica (SiO2) is perhaps the most undesirable inorganic deposit formed in process industrial waters, either in bulk or on surfaces, such as membrane heat exchangers or pipelines. Conventional mineral scale inhibitors do not inhibit its formation. Chemical cleaning is difficult and not free from hazards. Research on silica scale formation and prevention is on-going and has led to vario...
متن کاملEnvironmental Issues of Desalination
Environmental issues related to desalination are a major factor in the design and implementation of desalination technologies. An acceptable desalination plant is expected to meet environmental regulations; be cost-effective in terms of construction, operation and management, as well as the costs associated with monitoring and permit fees. Some major environmental concerns include issues relate...
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 ...
