Newton Fund - Industrial research on a clean process for delivering arsenic free safe water to affected communities in India

砷中毒导致的皮肤癌对印度东部的西孟加拉邦、贾坎德邦和比哈尔邦的5000多万人来说仍然是一个重大威胁，因为他们消耗了富含砷的地下水。已发表的文献表明，砷中毒只能通过向受影响社区提供清洁水来减轻。泵处理过滤方法虽然适用于企业，但由于吸附剂使用率高以及废物处理问题，在减轻砷中毒方面失败。该项目提议合并两项获奖的绿色技术，即BhaskarSen Gupta教授团队的地下除砷（SAR）技术和iest（前身为BESU Shibpur）的Amal过滤器，以提供负担得起的安全水。SAR不使用任何化学品，不产生废物，可将砷从200 ppb降至20 ppb，而Amal过滤器可去除剩余的砷，以符合WHO/USEPA 10 ppb的限制。作为工业研究的一部分，将安装三个这样的工厂。经过两年的工业研究，UKPL和IPL的目标是在HWU和iest的进一步技术/设计投入下将该过程商业化。

Arsenicosis leading to skin cancer remains a significant threat to 50+ million people in eastern Indian states of West Bengal, Jharkhand and Bihar through consumption of arsenic rich groundwater. Published literature indicate that arsenicosis can only be mitigated through provision of clean water to affected communities. Pump-and-treat filtration methods, although suitable for businesses, struggle due to high adsorbent use rates as well as waste disposal problems and fails miserably in mitigating arsenicosis. This project proposes to merge two award winning green technologies, viz. Subterranean Arsenic Removal (SAR) Technology from Prof BhaskarSen Gupta's team and Amal filter from IIEST (formerly BESU Shibpur) to provide affordable safe water. SAR does not use any chemical, produces no waste and can reduce arsenic from 200 ppb to 20 ppb, while Amal filter would remove the rest of the arsenic to comply with WHO/USEPA limit of 10 ppb. Three such plants will be installed as part of industrial research. UKPL and IPL are aiming to commercialise the process with further technical/design input from HWU and IIEST after two years' of industrial resarch.
