CMI, Texas, Inc.

Year Submitted: 2003

Process: Wastewater Treatment

Industry: Metal Fabrication

Wastes Reduced: Hazardous Waste

Equipment: Ultrafiltration

Location: Nuevo Laredo MEXICO

No. of employees: 800


CMI produces oily waste water from its cutting and cleaning operations. The wastewater was sent to Texas for deep well injection. To eliminate this costly procedure, CMI installed an ultrafiltration unit to separate the oil and water. After separation, the water can be discharged and meets regulatory limits for grease and oil. The oil is sent for energy recovery. CMI is in the process of purchasing an additional reverse osmosis unit that will produce water clean enough to reuse for cleaning.

Environmental Benefits:

CMI was disposing of approximately 3,000 gallons of oily wastewater per day into deep well injection prior to the installation of the ultrafiltration unit.

Details of Reductions

Additional Information :

CMI is saving over $3,000 a day from reduced disposal costs. The payback period on the ultrafiltration unit was 4 months. With other improvements to reduce generation of oily wastewater now on-line, CMI is still saving over $62,000 a month.
