SBIR Phase II: Water Purification Technology for Removal of Chemical and Biological Contaminants

这个小型企业创新研究（SBIR）第二阶段研究项目开发了一种低成本的水净化技术，用于去除生物和化学污染物。结合俄勒冈州大学的研究和得克萨斯大学许可的技术，一种专有的表面改性矿物吸附剂将隔离高浓度的化学污染物，如砷，铅，汞，PCE，TCE和MTBE。目前的努力将：a）优化能够去除重金属的特定双功能配体和矿物基质以满足EPA饮用水标准; B）证明能够从水流中选择性去除污染物的替代配体/基质组合; c）证明CCT水过滤器和紫外线灯组合符合EPA和加州饮用水要求; d）在欠发达地区现场测试该溶液。 目前，世界上三分之二的人口无法获得清洁用水，三分之一的人口无法获得可靠的水源。在世界某些地区，主要是不发达国家，水已经是最宝贵的必需品。来自联合国教科文组织赞助的世界水资源评估计划的执行摘要：“2000年，由于水卫生设施中与水相关的有害生物造成的估计死亡率......疾病。是221.3万。“这相当于每15秒就有一个人。在美国，一份2001年的EPA报告估计每年有超过两百万的美国人因受污染的水而生病。在中国，超过10亿人缺乏可接受的水资源。 在第二阶段的工作完成后，CCT将有一个完整的解决方案，使用被动和主动技术，为低成本，可持续的水净化模块。

This Small Business Innovation Research (SBIR) Phase II research project develops a low-cost, water purification technology for removal of biological and chemical contaminants. In combination with research at the University of Oregon and technology licensed from the University of Texas, a proprietary surface-modified mineral adsorbents will sequester high concentrations of chemical contaminants, such as arsenic, lead, mercury, PCE, TCE and MTBE. The current effort will: a) optimize specific bifunctional ligands and mineral substrates capable of removing heavy metals to meet the EPA drinking water standards; b) demonstrate alternative ligand/substrate combinations capable of selective removal of contaminates from a water stream; c) demonstrate qualification to EPA and California drinking water requirements of a CCT water filter and ultra-violet lamp combination; d) field test the solution in an underdeveloped location. Currently two-thirds of the world's population does not have access to clean water and one-third lack access to a reliable source of water. In certain parts of the world, mostly the underdeveloped world, water is already the most precious necessity. From the executive summary of the World Water Assessment Program sponsored by the United Nations under UNESCO: "In 2000, the estimated mortality rate due to water sanitation hygiene-associated ... diseases.. was 2,213,000." That equates to one person every 15 seconds. In the U.S., an 2001 EPA report estimates that over two million Americans get sick from contaminated water each year. In China, over one billion people lack acceptable water resources. At the completion of the Phase II effort, CCT will have a complete solution, using both passive and active technologies, for a low cost, sustainable water purification module.
