Recent testing of air-sparged hydrocyclone (ash) flotation technology for fine coal cleaning at the epri/codc test facility has shown that the ash system has great potential for utilization in the coal industry. however, effective utilization of this technology relies on optimum control andcontinual… More

The recently completed test program by penelec at the epri/cqdc test facility, homer city, pa, under doe contract de-ac22-88pc88853 has again demonstrated the effectiveness and the potential of ash flotation technology for fine coal cleaning. this test program confirmed the ash effectiveness with… More

Speech deception and voice "hijacking" techniques are now sophisticated beyond the ability of any single detection methodology. Deceptive speech detection requires an array of analysis tools to collectively provide an acceptable probability of detection. An effective Voice Authentication Monitoring… More

Oil removal from voluminous streams is difficult. research is being carried out to develop new bioremediation technologies to speed up the degradation process for the oil emulsions and dispersions. the time required for oil removal with today's technologies is unacceptably long, posing an… More

A rang of AF activities generate wastewater containing oily substances, emulsion=stabilizing agents, and insoluble materials, including Aqueous, Film-Forming Foam (AFFF). US AF is searching for a cost effective method to handle the problem. This problem in reality refers to two issues: a)… More

It is difficult to remove oil and AFFF from voluminous streams. Research has been continously carried out to develop new technologies to be employed in this field of application with little success. Air-sparged hydrocyclone (ASH) flotation technology is a new technology developed by the University… More
