THE PURPOSE OF THE PROPOSED PROJECT IS TO PROVIDE A PROOF OFCONCEPT EVALUATION OF AN INSTRUMENT CAPABLE OF MEASURING NO,02, AND SO2 USING UV ABSORPTION AND A PHOTODIODE ARRAY SPECTROPHOTOMETER. IF SUCCESSFUL, THIS INSTRUMENT WOULD SATISFY ALL THE REQUIREMENTS OF A CONTINUOUS EMISSION MONITORING SYSTEM REQUIRED BY THE ENVIRONMENTAL PROTECTION AGENCY. SINCE ALL THREE GASES WOULD BE MEASURED WITH A S ...

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 ...

IN NOVEMBER OF 1984 THE PRESIDENT SIGNED INTO LAW A SET OF FAR-REACHING AMENDMENTS TO THE RESOURCE CONSERVATION AND RECOVERY ACT OF 1976. UNDER THE NEW LAW, LAND DISPOSAL OF ALL HAZARDOUS WASTES IS TO BE BANNED OVER THE NEXT FIVE YEARS. WASTE REDUCTION, RECYCLE, AND INCINERATION ARE EMPHASIZED. PARTICULARLY TARGETED ARE WASTE STREAMS CONTAINING HALOG ENATED SOLVENTS AND ARSENIC DUE TO THE THREATS ...

SUCCESSFUL DRINKING WATER PURIFICATION REQUIRES PROPER COAGULATION, USUALLY WITH ALUM, FOR REMOVAL OF DISEASE TRANSMITTING ORGANISMS. THE GROWING NATIONAL NEED FOR IMPROVED PERFORMANCE OF PURIFICATION INVOLVING COAGULATION-FILTRATION COULD BEST BE HELPED BY USE OF AN AUTOMATED COAGULANT DOSE CONTROL INSTRUMENT. THE BEST TECHNOLOGY AVAILABLE NOW IS STREAMING CURRENT DETECTORS. THEIR MAJOR SHORTCOMI ...

SAFE, COST EFFECTIVE ALTERNATIVES TO CHLORINE TREATMENT OF DRINKING WATER FOR DISTRIBUTION AND DISINFECTION HAVE BEEN SOUGHT FOR SOME TIME. CHLORINE DIOXIDE IS A VIABLE ALTERNATIVE TO CHLORINE FOR THE TREATMENT OF EVEN POOR QUALITY WATER SUPPLIES AND THE REDUCTION OF POTENTIAL CANCER CAUSING CHLORINATED ORGANICS. ITS WIDESPREAD USE HAS BEEN INHIBITED BY THE COSTS AND/OR COMPLEXITY OF ITS PRODUCTIO ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...
