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 ...

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 ...

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 ...

Direct Energy Solutions proposes to design, fabricate and test a basic prototype decontamination device for building protection from chemical and biological weapons attack and the general enhancement of indoor air quality. The decontamination device generates metastable Singlet Delta Oxygen (SDO), O2 (a1¿), a strong oxidant of biological and chemical pathogens, from direct optical excitation of ...

This SBIR Phase II proposal addresses development of a field-portable, amperometric biosensor for monitoring organophosphorus (OP) and carbamate insecticides in water. The miniaturized biosensor will use a modified screen-printed microelectrode with high sensitivity and lowlimit of detection for OP and carbamate pesticides. This biosensor will be selective for OPs and carbamates. The enzyme use ...

This SBIR proposal describes development of a protable, low-power amperometric biosensor to detect ogranophosphorus and carbamate insecticides in water. A renewable, robust biosensor is proposed and will be designed to specifically detect insecticides based on an immobilized enzyme of a sensor electrode. This method will allow analysis of insecticides in water without significant dilluton or red ...

Polychlorinated biphenyls (PCBs) remain a significant environmental threat even though manufacturing of PCBs was discontinued 30 years ago. PCBs are toxic amd suspected to carcinogenic to humans and are therefore carefully monitored. Due to the chemical and thermal stability of PCBs in the environment and the continued use of rtansformers containing these chemicals, very specific regulations are ...
