Conventionally sewage treatment plant treats the sewage and the same is dried. The technology developed by Bhabha Atomic Research Centre (BARC) subjects the dried sludge to crushing and exposure to 10 kGy radiation dose. This kills the pathogens in the sludge and makes it safer for use. In the next step, BIO-NPK (Nitrogen Phosphorus Potassium) microorganisms are sprayed on to it to make it bio- fertilizer. The use of such bio-fertilizer provides organic carbon and other nutrients to the soil. The process also helps in recycling of the waste material to useful Bio-fertilizer.
