(Formerly Ted Davis Manufacturing) is a manufacturing and major worldwide supplier of disk drive components. Approximately 200 persons are employed at this facility. Over a six month period process changes and equipment modifications were instituted. These changes were accomplished using a team approach (management, quality control, production, procurement, environment and safety all represented.)
In 1992 Freon TMS was the chosen cleaner (3500 to 4000 lbs per week). With equipment modifications and process changes this system was eliminated and two aqueous cleaning lines were installed. Line 1: ultrasonic wash and ultrasonic rinse before drying. Line 2: a conveyor moves parts through a pre-soap, wash, rinse, virgin deionized water rinse and drying cycles.
HFC emissions eliminated (200,000 lbs per year to 0 in 1996.) Wastewater discharged directly to POTW.
