EMMC(entrapped mixed microbial cell) technology is the most current research projects within the last decade at the University of Hawaii. These R&D projects are focused on the applications in the biological treatment of domestic, industrial and agricultural wastewater under strictly limited land conditions that demand cost-effective treatment methods. In this seminar, both lab and pilot plant studies related to the potential applications in various wastewater treatment systems will be presented and discussed. The preparation of the EMMC carriers, process performance regarding the removal of oxygen demand material and nitrogen, sludge production, odor reduction, space saving, potential reuse/disposal will be presented. The cost evaluation of the EMMC technology will also be discussed. Furthermore, discussion of simultaneous removal of carbon and nitrogen in a single reactor will be presented. This may provide the simplification for the design and operation of conventional activated sludge processes.
