项目摘要

DESCRIPTION (provided by applicant): The water treatment product developed in this SBIR program will give more people the opportunity to live healthier lives and strengthen communities by increasing available water resources. The contamination of drinking water is an age-old problem. In recent decades, the pollution of ground and drinking water by organic chemicals has attracted increasing attention all over the world as man-made toxins (pharmaceuticals, plasticizers, pesticides, disinfectant by-products, etc.) continue to enter the worlds' drinking water reservoirs via wastewater, agricultural runoff, storm water, air pollution, and polluted soil. Exposure to these toxins through drinking water is leading to chronic, complex diseases; the burden of which falls primarily on socioeconomically disadvantaged communities. Removal of organic chemicals from drinking water is imperative to protect the health of the world's populations. Traditional adsorption technologies do not have the structural sophistication to allow for the simultaneous removal of multiple complex chemicals. Other purification technologies (i.e. reverse osmosis membranes and hydroxyl radicals) have failed to provide a simple and cost-effective means to remove the wide spectrum of organic chemicals now found in drinking water supplies. What's missing from the $3B US residential treatment market is a simple and cost effective POU product for the wide spectrum of difficult to remove and highly toxic trace organic chemicals. Through this SBIR project, Chemica aims to bring a timely new tool to the field of water treatment/purification that specifically targets difficult to remove contaminants in an easy-to-use and affordable manner. This will be achieved through applying Chemica's proprietary surface modification techniques to a robust carbon fiber substrate. Chemica's novel fiber is easily scalable and can be tailored to meet users' specific needs. The goal for this SBIR program is to produce a prototype modular cartridge containing a robust adsorbent with 5x faster adsorption rates over existing adsorbents and lower lifecycle costs compared to alternative water purification technologies. This will be achieved through the following Specific Aims: PHASE I Specific Aim 1. Comparison of Functionalized Fiber Modules with Conventional Water Purifiers PHASE II Specific Aim 1. Optimization and Large-Scale Production of Functionalized Fiber Adsorbent PHASE II Specific Aim 2. Design and Manufacture of Prototype Module to House the Fiber Adsorbent PHASE II Specific Aim 3. Performance Characterization of the Fiber Adsorbent and Module in the Real World Key words: drinking water, emerging contaminants, toxicity, adsorbent, carbon, pharmaceuticals, plasticizers, pesticides, disinfectant by-products, coordination chemistry, organic chemistry, VOC, separation

描述（由申请人提供）：在SBIR计划中开发的水处理产品将通过增加可用的水资源，为更多的人提供更健康的生活和加强社区的机会。饮用水污染是一个古老的问题。近几十年来，有机化学品作为人造毒素（药品、增塑剂、农药、消毒剂副产物等）对地下水和饮用水的污染日益引起全世界的关注这些水继续通过废水、农业径流、雨水、空气污染和污染的土壤进入世界饮用水水库。通过饮用水接触这些毒素正在导致慢性、复杂的疾病;其负担主要福尔斯在社会经济处境不利的社区。从饮用水中去除有机化学品对保护世界人口的健康至关重要。传统的吸附技术不具有允许同时去除多种复杂化学品的结构复杂性。其他净化技术（即反渗透膜和羟基自由基）未能提供一种简单和具有成本效益的方法来去除目前在饮用水供应中发现的广泛的有机化学品。美国30亿美元的住宅处理市场缺少的是一种简单且具有成本效益的POU产品，用于广泛的难以去除和剧毒微量有机化学品。通过这个SBIR项目，Chemica旨在为水处理/净化领域带来一种及时的新工具，专门针对难以以易于使用和负担得起的方式去除污染物。这将通过将Chemica专有的表面改性技术应用于坚固的碳纤维基材来实现。Chemica的新型光纤易于扩展，可根据用户的特定需求进行定制。该SBIR计划的目标是生产一种原型模块化滤芯，其中包含一种坚固的吸附剂，与现有吸附剂相比，吸附速率快5倍，与替代水净化技术相比，生命周期成本更低。这将通过以下具体目标实现：第一阶段具体目标1。功能化纤维模块与传统净水器的比较PHASE II具体目标1.功能化纤维吸附剂的优化和大规模生产第二阶段具体目标2.设计和制造容纳纤维吸附剂的原型模块PHASE II具体目标3.真实的世界中纤维吸附剂和组件的性能表征关键词：饮用水，新兴污染物，毒性，吸附剂，碳，药物，增塑剂，农药，消毒剂副产物，配位化学，有机化学，VOC，分离
