MASSACHUSETTS INSTITUTE OF TECHNOLOGY, MA, USA. A new technique known as shock electrodialysis has been developed to separate salt from water. It is an affordable, easy and effective method. Shock electrodialysis is comparable to conventional methods but this process does not involve some of the problems associated with popular desalination methods like boiling water that requires too much energy and clogging of filters. This new method is specifically designed to help disaster-stricken areas that are in dire need of clean and fresh drinking water.
MIT Mathematics and Engineering Professor, Martin Bazant, and his team developed a different separation system that is similar to conventional methods. Shock electrodialysis is not dependent on barriers to strain sodium particles from water. It uses a porous material called frit, which is made of small glass particles. There are electrodes attached to the sides that apply an electrical current to the flow of water inside. This enables the depleted and salt enriched water to separate. Increasing the current to a specific point produces a shockwave that creates a stark divide between the flows that can be detached into various channels. The resulting fresh water can be collected for consumption.
Shock electrodialysis’ practicality and effectivity satiate various needs on different extents. A good example is that it can be used in decontaminating water from areas that are affected by fracking. This is made possible via the electric current that is capable of killing certain bacteria. The water is being sterilized. The team hopes to revolutionize desalination methods for emergency purposes specifically in disaster areas. Water and electricity can be combined as a lifeline for those people suffering in disaster zones.
