NEW MEMBRANES FOR CARCINOGEN REMOVAL IN WATER TREATMENT

描述（改编自申请人的摘要）：饮用水的臭氧化 水对于使用当地威尔斯井或地表水的小社区是有吸引力的 水资源，只要能以合理的成本做到这一点。虽然氯 被广泛使用，并且比臭氧更便宜，它的使用导致 形成致癌的三卤甲烷。此外，氯已被发现是 对隐孢子虫的治疗无效。根据SBIR第一阶段赠款 来自NIH的紧凑膜系统（CMS）在实验室规模上证明， CMS的膜技术可以成功地用于实现高效臭氧 这将是商业上实用的水平，而膜寿命超过 1300小时时，暴露于臭氧和水也观察到。 在第二阶段，研究者将a）扩大中试规模水的装置尺寸 处理操作，B）采用CMS的膜技术来增强装置 性能和寿命，c）展示水流的有效臭氧化 在动物研究的帮助下掺入隐孢子虫，d）进行 在当地水处理厂进行中试规模实验，以及e）开发 详细的经济学方面的系统规模和计算成本权衡， 系统尺寸与每处理1000加仑水的成本。 拟议商业应用：不可用

DESCRIPTION (Adapted from Applicant's Abstract): The ozonation of drinking water is attractive for small communities that employ local wells or surface water sources, provided it can be done at a reasonable cost. Although chlorine is widely used and is cheaper to use than ozone, it's use results in the formation of carcinogenic trihalomethanes. Also, chlorine has been found to be ineffective in the treatment of cryptosporidium. Under a SBIR Phase I grant from the NIH, Compact Membrane Systems (CMS) demonstrated at lab-scale that CMS' membrane technology could be successfully used to achieve efficient ozone levels that would be commercially practical, while membrane lifetimes in excess of 1300 hours when exposed to ozone and water were also observed. In Phase II the investigator will a) scale-up device size for pilot-scale water treatment operations, b) employ CMS' membrane technology to enhance the device performance and longevity, c) demonstrate efficient ozonation of water streams spiked with Cryptosporidium with the aid of animal studies, d) undertake pilot-scale experiments at the local water treatment plant, and e) develop detailed economics with respect to system size and calculate cost trade-off for system size versus costs per 1000 gallons of water treated.
