The Small Business Innovation Research (SBIR) Phase II project seeks to develop a novel approach for fabrication of ceramic membranes that would provide a significant reduction in fabrication costs. Membrane filtration is becoming an important process for drinking water treatment. Much of this growth is due to development of low-cost polymeric membranes that can compete economically with traditional methods of water treatment. Ceramic membranes can be used to achieve the same level of water quality as provided by polymeric membranes, with several distinct advantages: ceramic membranes provide higher fluxes, reduced fouling rates, and longer lifetimes with fewer integrity issues. Historically, ceramic membranes have not been competitive with traditional methods or polymeric membranes due to high manufacturing costs. Recent developments that offset the high manufacturing costs have allowed ceramics to be competitive with polymerics in some markets. By developing the proposed innovation, ceramic membrane module cost will be further reduced, giving ceramics an advantage over currently employed polymeric membranes.Increased membrane usage in water treatment will lead to safer drinking water for the 90% of Americans that receive their water from community water systems. For the water systems that employ ceramic membranes, there will be less cost, maintenance, and concerns of system integrity failures. Additionally, the technology developed in this program would be applicable to ceramic microfiltration and ultrafiltration membranes for all food, beverage, chemicals, pharmaceutical, energy, wastewater, and water applications. Energy efficient separation processes requiring robust membranes would become more economically viable, potentially lowering the 4,500 T Btu of energy consumed annually for industrial separations.

小型企业创新研究（SBIR）II期项目旨在开发一种新型的制造陶瓷膜的方法，该方法将大大降低制造成本。 膜过滤已成为饮用水处理的重要过程。 这种增长的大部分是由于低成本聚合物膜的发展所致，这些膜可以与传统的水处理方法在经济上竞争。 陶瓷膜可用于达到与聚合膜提供的相同水平的水质，具有几种不同的优势：陶瓷膜提供更高的通量，降低的结垢率和更长的寿命，具有更少的完整性问题。 从历史上看，由于制造成本高，陶瓷膜与传统方法或聚合物膜没有竞争。 抵消高生产成本的最新发展使陶瓷在某些市场中与聚合物具有竞争力。 通过开发拟议的创新，将进一步降低陶瓷膜模块成本，使陶瓷比当前使用的聚合膜具有优势。在水处理中使用的膜使用膜的使用将导致90％的美国人从社区水系统中获得水。 对于采用陶瓷膜的水系统，对系统完整性故障的成本，维护和担忧将更少。 此外，该程序中开发的技术适用于所有食品，饮料，化学物质，药物，能源，废水和水应用的陶瓷微滤和超滤膜。 需要稳健膜的节能分离过程将在经济上变得更加可行，从而有可能降低每年用于工业分离的4,500 T BTU。
