Copper compounds have been used for centuries in marine antifoulants to inhibit biofouling. This anthropogenic copper is a potential problem in confined basins and in regions that experience limited mixing. In this research project, E Paint Company will explore the feasibility of developing novel self-polishing coatings that exploit natural methods of biofouling control to produce effective and ...

COAL TAR IS A BY-PRODUCT OF THE COAL GASIFICATION PROCESS USED WIDELY BETWEEN 1820 AND 1950 TO PRODUCE A NATURAL GAS SUBSTITUTE. DURING THAT TIME, BILLIONS OF GALLONS OF TAR WERE PRODUCED AT MORE THAN 1500 GAS MANUFACTURING FACILITIESLOCATED THROUGHOUT THE U.S. A LARGE PORTION OF THIS WASTE TAR REMAINS IN STORAGE OR WAS DISPOSED OF BY INJECTION INTO SUBSURFACE SITES. COAL TAR IS A MIXTURE OF HYDRO ...

Electronic waste (e-waste) is one of the most rapidly growing waste problems worldwide and has reached crisis proportions. The crisis relates not only to quantity, but also to the toxic nature of e-waste. Vast amounts of toxic materials such as lead, beryllium, mercury, cadmium, and brominated flame retardants are contained within the growing mountains of e-waste around the world. The United St ...

A number of very high-volume liquid chemicals form azeotropes with water and can be dehydrated to required purity levels only through the use of entrainers or drying agents. The handling and disposal of these additional chemicals present significant environmental risks. Recently, membrane pervaporation using both polymeric and inorganic membrane modules has been commercialized as a method to deh ...

Current aircraft coating systems consist of a top coat, chromated primer, and conversion coating, and typically are used for a maximum of only 6 years due mainly to decreased top coat performance. The entire coating system is removed by sanding or media-blasting down to bare metal, and an entirely new coating system is reapplied. This is primarily done because no method for selectively stripping ...

The proposed research will demonstrate a diesel particulate matter (PM) exhaust aftertreatment technology that exceeds the performance of the catalyzed diesel particle filter (CDPF) technologies currently being tested by the U.S. Environmental Protection Agency (EPA). Using a unique microwave-sensitive silicon carbide fiber filter cartridge, Industrial Ceramic Solutions¿ microwave-regenerated pa ...

RECENT PROMISING DEVELOPMENTS IN THE PETROLEUM INDUSTRY "PROFILE MODIFICATION TECHNOLOGY" (PMT) WILL BE EVALUATED FOR THEIR APPLICATION TO LEAKING LANDFILL SITES. PROFILE FLOW MODIFICATION TREATMENTS ARE USED TO INCREASE FLOW RESISTANCE IN HIGH PERMEABILITY AREAS FAR (75 FEET TO AS MUCH AS 1000 FEET) FROM THE INJECTION WELLBORE. THESE TREATMENTS CAN WITHSTAND FORMATION PRESSURES AND TEMPERATURES U ...

There has been an alarming increase in toxic cyanobacteria during the past 2 decades, with numerous poisonings reported from Australia to the United States. The increased toxic risks led the U.S. Environmental Protection Agency (EPA) to include cyanotoxins on the 1998 Contaminant Candidate List. However, most cyanobacterial blooms are not toxic. Further, bloom toxicity will change over time. T ...

STUDIES INDICATE THAT STRAIGHT SEPTAGE INTRODUCTION TO ACT IVATED SLUDGE PLANTS CAUSES SHOCK LOADING AND SUBSEQUENT VIOLATION OF EFFLUENT PERMIT STANDARDS. THIS PROJECT INTENDS TO EVALUATE DEWATERING OF SLUDGE BY THEUSE OF WIRE CLOTH SCREENING TO DETERMINE IF THE DEWATERED SLUDGE MEETS LANDFILL ACCEPTABILITY STANDARDS. IT INTENDS A ALSO TO DETERMINE IF THE RETURN OF THE FILTRATE TO THE S SEPTIC TA ...
