About Amritdhara Purifier  

Rainwater could be easily purified with this Amritdhara unit, which makes it an ideal use during a natural calamity like the Chennai flood. It can convert 20,000 litres of any kind of water into drinking water. It can be mounted on a truck and can be moved around.  

It is basically a process in which a majority of pollutants from impure water are removed by passing it under pressure through a semi-permeable membrane. For this, the water is first pumped from the source into the purification unit. It then undergoes a primary treatment to separate the heavy particles. This is followed by treatment of water with Aluminium Sulphate, also known as Alum, to initiate coagulation.
