The release of mercury into the environment via combustion processes has become an issue of concern for the US and the entire world. Major sources either are regulated or are under review to develop regulations to reduce emissions. ADA Technologies has successfully demonstrated the performance of a novel reactive scrubbing technology for the removal of vapor-phase mercury from incinerator exhaus ...

THE MAJOR OBJECTIVE OF THE RESEARCH PROPOSED IS EVALUATION OF THE TECHNICAL FEASIBILITY OF THE NEW DESIGN FEATURES OF THE FILTER AND A COMPARISON OF ITS PERFORMANCE WITH CONVEN- TIONAL FILTERS IN TREATMENT OF WASTEWATERS. THE MAJOR SPECIFIC FEATURE OF THE FILTER IS A STONE-GRANULAR MEDIA BED WHICH IS EXPECTED TO PROVIDE A NON CLOGGING OPERATION, LONGER FILTRATION RUNS AND GREATER DIRT CAPACITY THA ...

Not Available The Air Force desires compact, intelligent optical sensors for use on satellites and other unmanned space vehicles. Intelligent sensors combine detection, processing, and control functions onto a single package to allow for autonomous detection and interpretation of optical signals. A specific case where an intelligent optical system is needed is in the detection, processing, and ev ...

ELECTRIC ARC FURNACE DUST IS LISTED AS A HAZARDOUS WASTE. TOTAL PRODUCTION OF THIS DUST IS ESTIMATED TO BE 500,000 TONS AT SOME 77 LOCATION RANGING IN SCALE FORM LESS THAN 1,000 TONS TO OVER 20,000 TONS PER YEAR. A PROCESS IS PROPOSED WHICH MAY PERMIT ON-SITE, SIMPLE RECOVERY OF CONTAMINANT METALS IN THE DUST. THE PROCESS RECYCLES RECYCLES CHEMICAL REAGENTS AND AQUEOUS LEACH , MINIMIZIN COST AND A ...

Not Available In this Phase I proposal we outline a plan to develop a novel phase conjugate laser system capable of locking and tracking remote objects. The proposed system uses a pulsed laser with an intra-cavity four-wave mixing configuration. In this proposal we outline the operational principles of the system, showing how velocity and position of the target can be accurately measured. During ...

Drinking water filtration plants nationwide are failing to adequately reduce the public health risk due to exposure to sometimes lethal Cryptosporidium and other microbial particle levels. New regulations also will require reduction of dissolved organic carbon (DOC) to minimize the risk from potentially carcinogenic reaction by-products resulting from disinfection. Particle and DBP precursors ar ...

Direct Energy Solutons proposes to deliver a prototype air flow decontaminaton device design for building protection from chemical and bilogical attacks. The decontamination device generates singlet delta oxygen (SDO) on a photocatalyst bed for the destruction of contaminants entrained in an airflow. This HVAC-compatible, minimum pressure drop chem-bio decontaminaton system will: Use a proven n ...

Not Available We propose to develop latching micro-magnetic relays based on the geometry-dependant magnetization of permalloy cantilevers. Two stable states ( on and off ) in a micro-relay controlled by an external magnet have been demonstrated. An integrated coil will be designed and fabricated with the relay to achieve the electronic switching between the two stable states. To meet the Air Fo ...
