  • Treatment to Remove High-Strength Contaminants in Wastewater Generated in the Destruction of VX Nerve Agent: Development of Technology and Demonstration of Environmental Quality

    Shortly after the events of Sept. 11, 2001, the U.S. government accelerated efforts on eliminating potential terrorist threats across the U.S. – including those posed by storage of chemical warfare agents and weapons. As part of that effort, the U.S. Army is destroying its VX–nerve agent stockpile in Newport, Indiana. The Army has determined that elimination of this stockpile can be achieved best ...

  • Case Study: Truck Wash

    This facility washes out the internal tanks of tanker trucks. Generating 10,000 gallons/day of wastewater consisting of the residual liquid within the tanks combined with soaps, acids, and caustic cleaning products. The wastewater flowed into a central sump and was pumped into one of their two 5000 gallon Reaction Tanks. The operator then added Ferric Chloride (40 gallons), sulfuric acid (10 ...

  • Corrugator Sheet Plant 1

    A facility that made corrugated sheet board was using a specialty flocculant to treat their wastewater. Unfortunately, it treated the water only one half of the time to acceptable levels for reuse as starch makeup. The facility had paid $45,000 in the first 6 months of the year in chemical costs and $40,000 in haul-off costs to haul the majority of the treated water offsite. Integrated Engineers, ...

  • Mirror Plating Wastewater Treatment

    In the manufacturing of certain mirrors, a strong copper solution at low ph is used to apply a thin coating to the glass surface. After adhesion, the excess is washed off and collected as wastewater. The wastewater at this facility is treated using 4 chemicals: caustic to raise the pH to 8.5, DTC (dithiocarbamate) as a metal precipitant, an organic based coagulant, and an anionic flocculant. The ...

  • Ammunition Manufacturing

    An ammunition manufacturing facility was having problems removing copper and zinc from their 900 gpm wastewater system. The process used lime to raise the pH from 1.5 to 10, sodium carbamate for a metal precipitant, and an anionic flocculant to increase the flock size and get the solids to settle in the clarifier. Current chemical costs are estimated at $225,000/year with a significant amount of ...
