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.

小企业创新研究（SBIR）第二阶段项目旨在开发一种制造陶瓷膜的新方法，以显著降低制造成本。 膜过滤技术正逐渐成为饮用水处理的重要工艺。 这种增长主要是由于低成本聚合物膜的开发，这种膜可以在经济上与传统的水处理方法竞争。 陶瓷膜可用于实现与聚合物膜相同的水质水平，具有几个明显的优点：陶瓷膜提供更高的通量，降低的结垢率，以及更长的使用寿命和更少的完整性问题。 历史上，陶瓷膜由于高制造成本而不具有与传统方法或聚合物膜的竞争力。 最近的发展抵消了高制造成本，使陶瓷在某些市场上与聚合物竞争。 通过开发拟议的创新，陶瓷膜组件的成本将进一步降低，使陶瓷比目前采用的聚合物膜的优势。增加膜在水处理中的使用将导致更安全的饮用水为90%的美国人，他们从社区供水系统获得他们的水。 对于采用陶瓷膜的水系统，将有更少的成本，维护和系统完整性故障的关注。 此外，该计划开发的技术将适用于所有食品，饮料，化学品，制药，能源，废水和水应用的陶瓷微滤和超滤膜。 需要坚固膜的节能分离工艺将变得更加经济可行，可能降低工业分离每年消耗的4，500 T Btu能源。
