Scientist claims to have developed cost-effective plant to purify polluted lakes

A cost effective plant that can purify polluted lakes has been developed by scientist Rajah Vijay Kumar. 

The plant, which took four years to build, has been successfully tested in December last year, he claimed.

The technology, designed for wasted water recovery and management, known as Fine Particle Shortwave Thrombolytic Agglomeration Reactor (FPSTAR), uses zero chemicals and has ability to remove toxic substances such as heavy metals, ammonia, sulphur compounds, bacteria, fungus among others from water, he explained. 
 
Unlike sewage treatment plants (STP) and effluent treatment plants (ETP), the water processed by the plant can be used for drinking or recycling, he said.

It does need much space and can be set up over the waterbody without disturbing its flow, he added.

Stating that he has been approached by a Mexico delegation to set up the plant at one of their polluted rivers ‘Rio Lerma,’, he rued that he has not been approached by civic authorities from City yet.

“Many City lakes are polluted and have STPs or ETPs. They are not effective,” he observes.
One such FPSTAR plant has been set up at a coffee estate in Kodagu to purify coffee-wash water. It can process 25,000 litre of water everyday, he said.

Apart from lakes and rivers, laboratory trails and pilot operations, he said, have confirmed the plant could be used to treat landfill leachate water, contaminated ground water, coffee pulping wash water, brewery spent wash, distillery effluent, textile dying water, among others.

“It is completely computer

controlled multi-stage system and requires one operator operate it. The person needs to occasionally check the quality of output water. A control room could be set up near the plant.”

The plant, which runs on electricity, does not consume much energy, Vijay Kumar, who is Director of Scalene Energy Research Institute, said.
