Abstract
ABSTRACT: With shrinking facility budgets and increasingly stringent environmental regulations, United States Department of Defense (DoD) weapon system maintenance facilities are faced with the difficult challenge of maintaining regulatory compliance with limited resources. Moreover, the growing diversity in DoD workloads as well as the increased use of low volatile organic compound industrial cleaners has increased the presence of chelating substances found in industrial wastes and wastewaters. During industrial wastewater treatment, these chelating substances form highly stable complexes with heavy metals thus inhibiting them from being effectively removed from solution. Recently, a new sulfur-based redox industrial wastewater treatment method has been developed that has the potential to consistently meet water quality compliance standards for regulated heavy metals in the presence of chelating substances. The new sulfur-based redox chemistry method utilizes a proprietary chemical mixture (Compliance MX), which is added to industrial wastewater under controlled pH and oxidation-reduction conditions. The chemical mixture, which is applied to negate the effects of chelation, results in the rapid destabilization of heavy metal ions leading to the subsequent formation of metal precipitates that are easily removed through sedimentation. BENEFIT: Beyond having the capability of treating electroplating and metal finishing wastewaters in the presence of chelating substances, the sulfur-based redox chemistry method provides a number of other potential benefits to both DoD weapon system maintenance facilities as well as private industry including; 1) elimination of the need to employ the acidic reduction process for hexavalent chromium removal, 2) elimination of the need for chlorine and/or other chemical oxidants for treating chelating substances, 3) significant improvements to the occupational health and safety environment for facility employees, 4) lower compliance and regulatory risks to the wastewater treatment facility, 5) significant financial savings with regard to reducing hazardous waste disposal costs and 6) elimination of capital improvement expenditures required to achieve industrial waste source segregation.
