Aqueous film-forming foams (AFFFs) are among the most popular fire-fighting foams used against fuel and oil fires because of their effectiveness and their ease of application. Unfortunately, recent studies have shown that certain fluorosurfactants used in AFFFs are toxic to aquatic life and tend to accumulate in the blood of animals and humans. The manufacturer recently has phased out ...

During Phase I of this research project, ADA Technologies, Inc. (ADA) identified a new class of amended silicate sorbents, based on a novel amendment chemistry and amendment process. During Phase I, static bed testing identified sorbents with mercury capacities as high as 12,000 g per gram of sorbent. Testing of the new sorbents in a dynamic, in-flight test rig constructed during the P ...

Uncontrolled oxidation of sulfide minerals in mine wastes causes acid rock drainage (ARD) that contaminates receiving waters with acid and heavy metals. ARD is an enormous environmental problem, and the most significant environmental issue faced by the mining industry. Effectively dealing with ARD has been and continues to be a formidable challenge for which no global solutions exist. ...

Tunable diode laser spectroscopy (TDLS) is one of the most versatile and powerful detection technologies. Essentially, any contaminant can be detected, and with emerging cavity-enhanced techniques, sensitivities can be in the parts per trillion. Despite this tremendous potency, however, widespread use of TDLS has been prevented largely by the lack of economical, reliable, and wavelengt ...

The goal of this Phase I research project is to demonstrate the feasibility of an innovative Acoustic Biodiesel Synthesis Reactor (ABSR) with a biodiesel production cost of less than $0.30 per gallon over the cost of feedstock. The target feedstocks are brown, yellow, tallow, restaurant recycled, and trapped grease with high free fatty acid (FFA). The final target biodiesel costs will total $1.0 ...

Biocidal additives are vital for both the preservation of coatings in the can as well as for long-term coating integrity after applications. Anti-fungal additives are critical for delaying attack by fungal and algal growth once an architectural coating is in place. Biocidal coatings are designed to kill microbes and fungi by slowly and steadily releasing biocide from the dried film. Unfortunat ...

Biocidal additives are vital for both the preservation of coatings in the can as well as for long-term coating integrity after application. Antifungal additives are critical for delaying an attack by fungal and algal growth once an architectural coating is in place. Biocidal coatings are designed to kill microbes and fungi by slowly and steadily releasing biocide from the dried film ...

Mercury emissions from incinerators have long been recognized as an environmental issue. Current U.S. Environmental Protection Agency regulations call for the reduction of mercury emission by 85 percent for municipal, hazardous, and medical waste incineration sources. The most common approach for mercury control from these sources is the use of activated carbon, either injected as a po ...

Eltron Research, Inc., is seeking to develop an automated, solar-powered, flow-through prototype acid mine drainage (AMD) treatment system for unattended mitigation of AMD at thousands of abandoned mines and AMD currently entering the environment without any treatment. Harmful metals that are not readily degraded or detoxified enter the environment in significant quantities via nume ...

The goal of this Phase I research project is to develop a polymeric system that is capable of binding and removing heavy metal ions from an acid mine drainage (AMD) stream. In addition, this system will undergo controlled release of these metal ions that does not depend on changes in pH or the introduction of special solvents. The proposed system will undergo multiple cycles of metal binding an ...
