THIS RESEARCH INVESTIGATES THE FEASIBILITY OF DEVELOPING AN INNOVATIVE OPTRODE DEVICE FOR THE DETECTION, IDENTIFICATION, AND QUANTIFICATION OF TRACE LEVELS OF CHEMICAL CONTAMINANTS IN WATER. THIS FIBER OPTIC BASED INSTRUMENT WILL HAVE A RESPONSE DETECTOR AND CAN MEASURE CONCENTRATIONS OF CONTAMINANTS AT PARTS PER BILLION CONCENTRATIONS. IT IS ALSO ANTICIPATED THAT THIS INSTRUMENT WILL BE ABLE TO I ...

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 ...

NITROUS OXIDE, N2O, IS A STABLE GAS THAT CONTRIBUTES TO BOTHTHE GREENHOUSE EFFECT PROBLEM AND OZONE DEPLETION IN THE STRATOSPHERE. AMBIENT N2O LEVELS ARE INCREASING FROM UNKNOWN SOURCES. NO CONTINUOUS, ON-LINE INSTRUMENT IS COMMERCIALLY AVAILABLE TO MEASURE N2O FROM FOSSIL FUEL COMBUSTION SOURCES TO ASSESS AND CONTROL N2O EMISSIONS. PSI TECHNOLOGY COMPANY PROPOSES TO DEVELOP A CONTINUOUS, ON-LINE ...

Ammonia has an important role in the chemistry of the atmospheric environment and air quality. Ammonia emissions are a major environmental concern, yet they remain poorly quantified. There is a need for a sensitive ammonia instrument to monitor emissions and evaluate their effects on the local and regional environments. An instrument capable of continuous monitoring is required to understand diurn ...

Infrared (IR) imaging is the best method for detecting leaks of pollutant gases, but current technology based on cooled IR imagers is far too expensive ($75,000 to $150,000) for everyday field use by those who need it to meet regulatory limits¿electric and petrochemical utilities, manufacturing plants, and businesses such as supermarkets. Agiltron will demonstrate a new class of IR imager instrum ...

This proposed project directly addresses an U.S. Environmental Protection Agency (EPA) calling for improved detection and measurement techniques including screening kits for algal neurotoxins (especially cyanobacterial anatoxin) and cytotoxins in drinking water systems. Bloom-forming cyanobacteria have been observed in water bodies, including drinking water reservoirs all over the world. Several ...
