As the world's population continues to grow, existing water supplies will become increasingly insufficient. As more and more water is required to meet mankind's needs, desalination of sea water will become an increasingly important source of useable water. Any comprehensive plan addressing mankind's energy usage or ecologic impact must account for the effect of desalination; responsible development requires attention to the most energy-efficient methods of purifying water. Proposed project involves hardness reduction of sea water using thermal distillation method with the help of peltier module for thermoelectric heating and cooling purpose. The software and hardware required to implement the hardness reduction unit are explained and its operation is described. Hardness reduction of sea water thus helps us to reduce the hardness of sea water and convert it into desalinated water with lesser consumption of power.

Peltier Module, SMPS, TDS-EC Meter, pH Meter.
