  • Designed treatment program for FGD Wastewater at DTE Monroe Power Plant which has a capability to produce 3,000 megawatts. Total Water usage at the plant is over 600,000 gpm.

  • Developed cooling water, boiler water, and wastewater treatment program for Dow Chemical Midland Plant saving over $250,000 yearly in chemical cost with improved performance.

  • Developed a chemical treatment program and helped with the design of the DTE Monroe Bottom Ash River Water System. The current system reduces turbidity of the 9,000gpm bottom ash water from a high of 1,000 ntu during dumping to <30 ntu in the discharge.

  • Engineered chemical filtration treatment system for DTE Energy lake water removal of turbidity and organics saving $250,000 yearly.

  • Designed million-gallon pond water treatment program for phosphate removal at Spring Valley College reducing phosphate from 4.27ppm to 0.09ppm.

  • Developed a patent pending technology to prevent bromate formation during 1,4 Dioxane destruction of groundwater in aquifer contamination.
