Worldwide Alloy Surfacing, Inc. (WWASI)

Year Submitted: 2005

Process: Cooling Towers

Industry: Paint/Coating

Wastes Reduced: wastewater

Location: Houston TX

No. of employees: 7

Contact: Ed Jones

Phone: 281/469-0042



Description:

Worldwide Alloy Surfacing, Inc. (WWASI) is a tungsten carbide coating facility. It uses plasma guns to accelerate tungsten carbide powder and shoot it onto the surface of oil and gas exploration and drilling equipment to form a super hard coating. Approximately 1500-2000 gallons of ground water were used daily to cool the plasma guns. The company used to discharge the wastewater into a ditch. Although the water did not contact the process, it was characterized by a higher temperature (115 oF) at the point of discharge. This was a matter of concern. The company had two options: 1) to obtain a permit or 2) to decrease the temperature of the discharged water close to the ambient temperature and then discharge it to the ditch. The company was encouraged to go with the second option and install a cooling tower and recycle the water. In a cooling tower, the latent heat of water vaporization is used to transfer heat to the atmosphere by exposing the water to air.

P2 Application:

Installation of a cooling tower to lower the temperature of wastewater by about 20 oF and recycle the water.

Environmental Benefits:

Approximately half a million gallons of ground water is saved annually.

Details of Reductions

Additional Information :

At one dollar per 1000 gallons, an equivalent of $500.00 is saved annually.
