    RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

    A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages. The measuring method is based on thermal atomization of mercury from a sample using a PYRO-915+ attachment and its consequent determination by flameless AAS with Zeeman background correction using the RA-915M mercury analyzer. The total time needed for determination of mercury is not longer than 2 minutes. RA-915+/915M is compliant with US EPA 7473 and ASTM D7622 methods.

  • RCRA Waste Processing

    With over 40 million tons of recycled waste in the U.S. each year, operators are fervently searching for innovative methods to treat and dispose of RCRA wastes. VulcanĀ® Systems' thermal desorption technology is a proven method for recycling RCRA wastes in a manner that is efficient, affordable, and compliant with the Resource Conveservation and Recovery Act of 1976. The technology devolatizes hydrocarbons and captures them in a condensor for potential use in fuel blending, while also allowing the delisted end product to be disposed of in a more safe and secure manner. According to the EPA's website, "[the] EPA tried to develop hazardous waste regulations that balance the conservation of resources, while ensuring the protection of human health and the environment." VulcanĀ® Systems' technology meets the EPA's regulations to ensure that hydrocarbons can be re-used and, RCRA Waste, now delisted, can be appropriately disposed of without damage to the environment or public health.
