A novel idea of coating poly-sulfone on a porous candle resulted in the development of a ‘point of use’ water purifier for removal of bacteria and virus. This device does not require any electricity or chemicals. Removal of suspended particulates, colour and odour are additional benefits.  The know-how has been transferred to twenty five (25) parties for deployment in a commercially viable manner. Lakhs of units have been sold out by our licensees. Rural adaptability of the water purification technologies has been demonstrated

In order to address energy crisis and climate change issues, nuclear/ renewable energy based desalination and water purification systems have been developed. India is one of the leading countries in nuclear desalination. BARC has set up the largest nuclear desalination demonstration plant (NDDP) of 6.3 MLD capacity coupled to Madras Atomic Power Station (MAPS). It is based on hybrid Multi-Stage Flash Reverse Osmosis (MSF-RO) technology producing two qualities of water such as distilled water for high end applications and potable water for drinking & other uses. The requirement of seawater, steam and electricity is met from MAPS. Co-location of desalination and power plants has the benefit of sharing the resources and infrastructural facilities.

Nuclear Desalination Demonstration Plant (NDDP) at Kalpakkam for Sea Water Desalination (6.3 MLD capacity)

Desalination being energy intensive process, the utilization of nuclear waste heat for sea water desalination, was demonstrated by setting up a low temperature (LT) desalination plant coupled to nuclear research reactor at Trombay.

Solar desalination is attractive for remote and rural areas where, grid electricity is not available or the voltage is not stable. Solar PV-powered desalination/water purification systems developed by BARC are suited for community level plants for producing clean water from brackish water. It can be used in urban areas also.
