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）：该 SBIR 计划开发的水处理产品将通过增加可用水资源，让更多人有机会过上更健康的生活并加强社区建设。饮用水污染是近几十年来的一个老问题。随着人造毒素（药品、增塑剂、杀虫剂、消毒剂副产品等）不断进入世界饮用水中，有机化学品对地下水和饮用水的污染日益引起全世界的关注。通过废水、农业径流、雨水、空气和受污染的土壤接触这些毒素会导致慢性、复杂的疾病，其负担主要落在社会经济弱势群体身上。传统的吸附技术结构复杂，无法同时去除多种复杂的化学物质（例如反渗透膜和水）。羟基自由基）未能提供一种简单且具有成本效益的方法来去除目前饮用水供应中发现的各种有机化学物质，而 30 亿美元的美国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。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，专门针对难以去除的污染物，且易于使用且价格实惠。方式。这通过将 Chemica 的专有表面改性技术应用于坚固的碳纤维基材来实现 Chemica 的新型纤维易于扩展，并且可以根据用户的特定需求进行定制。该 SBIR 项目的目标是生产包含坚固的模块化滤芯的原型。与现有吸附剂相比，吸附剂的吸附速度快 5 倍，并且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来实现：第一阶段具体目标 1. 比较。具有传统净水器的功能化纤维模块第二阶段具体目标 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第二阶段具体目标 3. 功能化纤维吸附剂的性能表征现实世界中的纤维吸附剂和模块关键词：饮用水、新兴污染物、毒性、吸附剂、碳、药品、增塑剂、农药、消毒剂副产物、配位化学、有机化学、VOC、分离
