Scientists from the National Chemical Laboratory (NCL), Pune in collaboration with the Water Technology Initiative under the Department of Science & Technology (DST), GoI has developed a novel technology to disinfect water.
The technology named ‘SWASTIIK’ (Safe Water and Sustainable Technology Initiative from Indian Knowledgebase) is a combined solution for not just disinfecting water, but for offering possible health benefits of natural oils.
Pathogenic microorganisms in water are one of the primary root-cause of water-borne diseases.
Although, chemical processes such as chlorination strive to do away with water impurities, the formation of carcinogenic disinfection by-products poses a serious health hazard.
Thus, it is imperative to develop a technology that provides safe, healthy and cost-effective drinking water with substantial ease of operation, free of harmful disinfectant by-products.
About the technology:
SWASTIIK technology is a unique and rather rare amalgamation of modern technology and traditional Ayurvedic knowledge that claims to disinfect water completely.
The technique uses hydrodynamic cavitation, combining chemistry, biology, and chemical engineering, with natural resources in the form of natural oils and plant extracts.
The process involves boiling of a liquid (water) as a result of pressure reduction called cavitation. It also uses natural oils with antimicrobial properties to eliminate harmful bacteria, including antimicrobial-resistant bacteria.
How it’ll benefit people?:
The technology developed by scientists from the National Chemical Laboratory (NCL) and Department of Science & Technology (DST) has significantly increased efficiency and reduced the cost of water treatment.
Further, it was observed that the increased rate of disinfection using oil can drastically reduce the time of operation, consequently reducing the cost as compared to other advanced treatment processes.
Its health benefits include providing safe drinking water that can boost immunity, an important aspect as underlined during the current pandemic times.
About the team:
Scientists from the National Chemical Laboratory (NCL) and Department of Science & Technology (DST) developed this path-breaking technology to disinfect water sustainably.
Dr. V M Bhandari and his group at the CSIR-NCL Pune, with support from the DST, developed the hybrid technology.
