                            <div align="justify">-The Times of India<br /><br /><em>Kolkata: </em>Here's good news for the city where several pockets are contaminated with arsenic-affected water. The Indian Institute of Technology-Kharagpur has developed an ultra-low cost eco-friendly laterite based arsenic filter for providing safe drinking water.<br /><br />The innovation has won Sirshendu De, the head of chemical engineering department, the Innovation Award 2016 from the Indian Desalination Association (South Zone).<br /><br />&quot;In India and Bangladesh, it is generally agreed that arsenic contamination of groundwater is of geological origin and derives from the geological strata. More than 200 million people are affected worldwide by arsenic menace and over 100 million people in India and Bangladesh are exposed to arsenic contamination risk. The need of the hour is an ultra-low cost, easy-to-handle solution for rural households,&quot; said De.<br /><br />The indigenous material developed by De is capable of adsorbing arsenic to the extent of 32mg per gram. &quot;It is made from naturally occurring red laterite soil. This material has undergone chemical treatment to enhance its capabilities to adsorb arsenic. Moreover, an optimized design of a filter, with the material, has been formulated as well that enjoys a plethora of advantages,&quot; De added.<br /><br />&quot;The ultra-low cost of the filter is more appropriate for the socio-economic conditions of our country, especially when the filter has no power requirement. The arsenic concentration of filtrate is always within the WHO drinking water permissible limit, independent of the ground water concentration. Also, the filter comparatively has extremely long life of about five years with no regeneration of the adsorbent (filter medium) required during its lifetime. The filter has facilities such as removal of arsenic (below 10 ppb), iron (below 0.3 ppm) and bacteriological contamination (more than 98%) together in a single unit. Upon exhaustion of the filter, the medium can be safely dumped without any risk of leaking and further contamination,&quot; he explained.<br /><br />The technology has been featured in the preferred list of the central government's department of science and technology's compendium of arsenic mitigation plan adopted for the nation.<br /><br />&quot;We have recently transferred the technology to a company that is already in the process of setting up a production unit. The filter medium will cost around for Rs 500 for a 100-litre per day capacity filter,&quot; De said. </div><div align="justify">&nbsp;</div><div align="justify"><em>The Times of India, 4 March, 2016, please <a href="http://timesofindia.indiatimes.com/city/kolkata/IIT-Kharagpur-develops-arsenic-filter-for-the-aam-aadmi/articleshow/51250227.cms" title="http://timesofindia.indiatimes.com/city/kolkata/IIT-Kharagpur-develops-arsenic-filter-for-the-aam-aadmi/articleshow/51250227.cms">click here</a> to access </em><br /></div>

                            <div align="justify">-The Times of India<br /><br /><em>Kolkata: </em>Here's good news for the city where several pockets are contaminated with arsenic-affected water. The Indian Institute of Technology-Kharagpur has developed an ultra-low cost eco-friendly laterite based arsenic filter for providing safe drinking water.<br /><br />The innovation has won Sirshendu De, the head of chemical engineering department, the Innovation Award 2016 from the Indian Desalination Association (South Zone).<br /><br />&quot;In India and Bangladesh, it is generally agreed that arsenic contamination of groundwater is of geological origin and derives from the geological strata. More than 200 million people are affected worldwide by arsenic menace and over 100 million people in India and Bangladesh are exposed to arsenic contamination risk. The need of the hour is an ultra-low cost, easy-to-handle solution for rural households,&quot; said De.<br /><br />The indigenous material developed by De is capable of adsorbing arsenic to the extent of 32mg per gram. &quot;It is made from naturally occurring red laterite soil. This material has undergone chemical treatment to enhance its capabilities to adsorb arsenic. Moreover, an optimized design of a filter, with the material, has been formulated as well that enjoys a plethora of advantages,&quot; De added.<br /><br />&quot;The ultra-low cost of the filter is more appropriate for the socio-economic conditions of our country, especially when the filter has no power requirement. The arsenic concentration of filtrate is always within the WHO drinking water permissible limit, independent of the ground water concentration. Also, the filter comparatively has extremely long life of about five years with no regeneration of the adsorbent (filter medium) required during its lifetime. The filter has facilities such as removal of arsenic (below 10 ppb), iron (below 0.3 ppm) and bacteriological contamination (more than 98%) together in a single unit. Upon exhaustion of the filter, the medium can be safely dumped without any risk of leaking and further contamination,&quot; he explained.<br /><br />The technology has been featured in the preferred list of the central government's department of science and technology's compendium of arsenic mitigation plan adopted for the nation.<br /><br />&quot;We have recently transferred the technology to a company that is already in the process of setting up a production unit. The filter medium will cost around for Rs 500 for a 100-litre per day capacity filter,&quot; De said. </div><div align="justify">&nbsp;</div><div align="justify"><em>The Times of India, 4 March, 2016, please <a href="http://timesofindia.indiatimes.com/city/kolkata/IIT-Kharagpur-develops-arsenic-filter-for-the-aam-aadmi/articleshow/51250227.cms" title="http://timesofindia.indiatimes.com/city/kolkata/IIT-Kharagpur-develops-arsenic-filter-for-the-aam-aadmi/articleshow/51250227.cms">click here</a> to access </em><br /></div>

                            <div align="justify">-The Times of India<br /><br /><em>Kolkata: </em>Here's good news for the city where several pockets are contaminated with arsenic-affected water. The Indian Institute of Technology-Kharagpur has developed an ultra-low cost eco-friendly laterite based arsenic filter for providing safe drinking water.<br /><br />The innovation has won Sirshendu De, the head of chemical engineering department, the Innovation Award 2016 from the Indian Desalination Association (South Zone).<br /><br />&quot;In India and Bangladesh, it is generally agreed that arsenic contamination of groundwater is of geological origin and derives from the geological strata. More than 200 million people are affected worldwide by arsenic menace and over 100 million people in India and Bangladesh are exposed to arsenic contamination risk. The need of the hour is an ultra-low cost, easy-to-handle solution for rural households,&quot; said De.<br /><br />The indigenous material developed by De is capable of adsorbing arsenic to the extent of 32mg per gram. &quot;It is made from naturally occurring red laterite soil. This material has undergone chemical treatment to enhance its capabilities to adsorb arsenic. Moreover, an optimized design of a filter, with the material, has been formulated as well that enjoys a plethora of advantages,&quot; De added.<br /><br />&quot;The ultra-low cost of the filter is more appropriate for the socio-economic conditions of our country, especially when the filter has no power requirement. The arsenic concentration of filtrate is always within the WHO drinking water permissible limit, independent of the ground water concentration. Also, the filter comparatively has extremely long life of about five years with no regeneration of the adsorbent (filter medium) required during its lifetime. The filter has facilities such as removal of arsenic (below 10 ppb), iron (below 0.3 ppm) and bacteriological contamination (more than 98%) together in a single unit. Upon exhaustion of the filter, the medium can be safely dumped without any risk of leaking and further contamination,&quot; he explained.<br /><br />The technology has been featured in the preferred list of the central government's department of science and technology's compendium of arsenic mitigation plan adopted for the nation.<br /><br />&quot;We have recently transferred the technology to a company that is already in the process of setting up a production unit. The filter medium will cost around for Rs 500 for a 100-litre per day capacity filter,&quot; De said. </div><div align="justify">&nbsp;</div><div align="justify"><em>The Times of India, 4 March, 2016, please <a href="http://timesofindia.indiatimes.com/city/kolkata/IIT-Kharagpur-develops-arsenic-filter-for-the-aam-aadmi/articleshow/51250227.cms" title="http://timesofindia.indiatimes.com/city/kolkata/IIT-Kharagpur-develops-arsenic-filter-for-the-aam-aadmi/articleshow/51250227.cms">click here</a> to access </em><br /></div>

IIT-Kharagpur develops arsenic filter for the aam aadmi

Published on Mar 6, 2016   Modified on Mar 6, 2016

-The Times of India Kolkata: Here's good news for the city where several pockets are contaminated with arsenic-affected water. The Indian Institute of Technology-Kharagpur has developed an ultra-low cost eco-friendly laterite based arsenic filter for providing safe drinking water. The innovation has won Sirshendu De, the head of chemical engineering department, the Innovation Award 2016 from the Indian Desalination Association (South Zone). "In India and Bangladesh, it is generally agreed that arsenic contamination of groundwater is of geological origin and derives from the geological strata. More than 200 million people are affected worldwide by arsenic menace and over 100 million people in India and Bangladesh are exposed to arsenic contamination risk. The need of the hour is an ultra-low cost, easy-to-handle solution for rural households," said De. The indigenous material developed by De is capable of adsorbing arsenic to the extent of 32mg per gram. "It is made from naturally occurring red laterite soil. This material has undergone chemical treatment to enhance its capabilities to adsorb arsenic. Moreover, an optimized design of a filter, with the material, has been formulated as well that enjoys a plethora of advantages," De added. "The ultra-low cost of the filter is more appropriate for the socio-economic conditions of our country, especially when the filter has no power requirement. The arsenic concentration of filtrate is always within the WHO drinking water permissible limit, independent of the ground water concentration. Also, the filter comparatively has extremely long life of about five years with no regeneration of the adsorbent (filter medium) required during its lifetime. The filter has facilities such as removal of arsenic (below 10 ppb), iron (below 0.3 ppm) and bacteriological contamination (more than 98%) together in a single unit. Upon exhaustion of the filter, the medium can be safely dumped without any risk of leaking and further contamination," he explained. The technology has been featured in the preferred list of the central government's department of science and technology's compendium of arsenic mitigation plan adopted for the nation. "We have recently transferred the technology to a company that is already in the process of setting up a production unit. The filter medium will cost around for Rs 500 for a 100-litre per day capacity filter," De said.   The Times of India, 4 March, 2016, please click here to access
