Lead Battery Recycling Wastewater - Batch treatment of lead-acid battery recycling plant wastewater with B9 decreased lead, copper, and antimony levels to below detectable limits of less than 5 ppb. Iron was decreased by 99.3%, zinc by 82%, and roughly half of the manganese was captured.
Gold Ore Processing Effluents - Mercury levels up to 34 ppm in gold-cyanide leachate solutions (avg. pH 10) from an active mine in Peru were decreased to 8 ppb within 15 minutes by B9. The amount of cadmium and lead in the leachate was also markedly reduced. A safe, permanent mercury removal method at the alkaline pH values found in gold-cyanide solutions was non-existent until the use of B9.
Acid Mine Drainage (AMD) Remediation - Application of B9 to water inside and at several discharge points from an abandoned Eastern Kentucky coal mine reduced iron and manganese levels more effectively than the traditional AMD treatment involving the addition of lime and peroxide. Use of B9 eliminates the need for disposal of large volumes of hazardous secondary sludge containing metal hydroxides and gypsum generated from lime and peroxide use.
Acid Mine Drainage (AMD) Mitigation - Coating coal refuse with B9 dissolved in ethanol suppressed the dissolution of pyrite (FeS2) and other metal sulfides that otherwise would have developed into AMD. While iron leaching was inhibited to the greatest extent, decreases in the amounts of cobalt, copper, manganese, nickel and zinc released from the coal were also achieved.
Elemental Mercury Spill - Broken manometers, formerly used for measuring flow rates in natural gas pipelines, have resulted in soil contamination by elemental mercury. Depending on the dosage, B9 prevented leaching of mercury by permanently capturing 82.6 – 99.6% of the element in soil samples that had an average mercury level of 10.3 mg per g of soil.
Chlor-Alkali Plant Mercury Contamination - Two wells near a former chlor-alkali plant had mercury contamination of 66 and 188 ppb, respectively. B9 treatment of water from these wells reduced mercury levels to below detectable limits of 0.05 ppb within 15 minutes.
Arsenic-Contaminated Water Field tests of a B9 filtration column indicated that B9 can reduce the amount of arsenic in affected water from 220 ppb (an amount 22 times the EPA and WHO exposure limit of 10 ppb) to less than 5 ppb.
Clean Air Technology - Work is currently in progress to develop methods of applying B9 for the gas-phase capture of mercury and other toxic metals from the flue gases of coal-fired power plants, waste incinerators, and crematoriums.
Green Technology - The movement towards greater energy conservation has flooded the market with mercury-containing compact fluorescent lamps (CFLs) without an adequate means to deal with these products at their end of life. B9 that is ground up with the spent CFLs will prevent the unintentional discharge of elemental mercury.
Agricultural Legacies - The B9 treatment of agricultural areas contaminated with organomercurial and organoarsenical compounds formerly used in fungicides, herbicides, and pesticides can prevent the mobilization of these toxic species to ground and surface waters.
Electroplating Industry - B9 will selectively precipitate and allow recovery of zinc from electroplating effluents.
