CURRENT AND FUTURE LEGISLATION WILL REQUIRE U.S. INDUSTRY TO TREAT MANY ORGANIC SOLVENT-CONTAINING AIR STREAMS NOW BEING DISCHARGED TO THE ATMOSPHERE. STREAMS OF THIS TYPE ARE PRODUCED BY PROCESSES SUCH AS PAINT REMOVAL AND METAL DEGREASING, AND IN PAINTING AND COATING OPERATIONS. MEMBRANE TECHNOLOGY AND RESEARCH (MTR) HAS DEVELOPED A MEMBRANE VAPOR RECOVERY PROCESS THAT IS ABLE TO REMOVE SOLVENT ...

DILUTE ACETIC ACID WASTEWATER STREAMS ARE PRODUCED IN LARGE QUANTITIES BY THE SYNTHETIC ORGANIC CHEMICAL INDUSTRY, FOR EXAMPLE, IN THE SYNTHESIS OF TEREPHALATE. RECOVERY OF ACETIC ACID FROM THESE WASTEWATERS FOR IN-PROCESS RECYCLING OF THE ACID WOULD REDUCE WASTE AND SAVE VALUABLE RESOURCES. THIS PROPOSAL DESCRIBES THE DEVELOPMENT OF A POROCESS THAT COMBINES SELECTIVE DIALYSIS FOLLOWED BY BIPOLAR- ...

SMALL WATER SYSTEMS ARE INCREASINGLY CHALLENGED TO COMPLY WITH THE SAFE DRINKING WATER ACT. EXISTING TECHNOLOGIES IMPOSE HEAVY OPERATIONAL BURDENS ON SMALL SYSTEMS AND PROVIDE ONLY NARROWLY FOCUSED SOLUTIONS. POLAR SPRING CORPORATION PROPOSES TO DEMONSTRATE THE FEASIBILITY OF DIRECTIONAL FREEZE CRYSTALLIZATION (DFC) TO SIGNIFICANTLY REDUCE THE CONCENTRATION OF DISSOLVED SOLIDS, ORGANIC CHEMICAL AN ...

THE PROPOSAL IS AIMED AT DEVELOPING AN ULTRASONIC TECHNOLOGY THAT CAN BE UTILIZED AS THE BASIS TO BUILD NONDESTRUCTIVE OFF-LINE MEASUREMENT INSTRUMENTS THAT CAN BE USED TO ESTABLISH THE QUALITY OF ADVANCED COMPOSITE MATERIALS USED IN AEROSPACE, MARINE, AND AUTOMOTIVE INDUSTRIES. THE ULTRASONIC TECHNOLOGY COULD REPLACE THE CURRENT INDUSTRIAL PRACTICE WHICH IS ENVIRONMENT-POLLUTING AND HAZARDOUS WAS ...

"Before entering the national pipeline distribution system, all natural gas must be dried, which is currently achieved using glycol dehydrators. However, the glycol dehydrators extract hazardous volatile organic compounds (VOCs) from the raw natural gas streams, In the U.S. alone the VOC emissions from dehydrators total an estimated 44,000 tons per year, half of which are benzene, toluene, ethyl ...

"As part of its mission to protect human health and the environment, the U.S. Environmental Protection Agency is dedicated to developing and promoting innovative cleanup strategies that restore contaminated sites to productive use, reduce associated costs, and promote environmental stewardship. However, in adopting this strategy there will be an increasing need to implement a more cost effective, ...
