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

导致皮肤癌的砷中毒仍然是印度东部西孟加拉邦、恰尔肯德邦和比哈尔邦5000多万人的重大威胁，因为他们消耗了富含砷的地下水。已发表的文献表明，只有通过向受影响的社区提供清洁的水才能减轻砷中毒。泵和治疗过滤方法虽然适用于企业，但由于较高的吸附剂使用率和废物处理问题而苦苦挣扎，在缓解砷中毒方面失败得很惨。该项目提出融合两项获奖的绿色技术，即。BhaskarSen Gupta教授团队的地下砷去除(SAR)技术和IIEST(前身为Besu Shibpur)的Amal Filter提供了负担得起的安全饮用水。合成孔径雷达不使用任何化学品，不产生任何废物，可以将砷从200 ppb降至20 ppb，而Amal Filter将去除其余的砷，以符合世卫组织/美国环保局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。UKPL和IPL的目标是在经过两年的工业研究后，通过HWU和IIEST的进一步技术/设计投入，将该工艺商业化。

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.
