JHI provided a variety of engineering services to Oregon Steel Mills in response to their need for an improved water system to provide treated cooling water to steel making equipment. The project began with a study of the existing spray pond system and establishment of mass and thermal balances for the system. Various options to increase flow and cooling capacity were investigated and a cooling tower system was recommended. A new substation was provided and the instrumentation and controls were integrated into the existing TI master controllers. In addition to the cooling requirement, substantial amounts of solid and oil contaminants were introduced into the system, so JHI studied several approaches to water cleanup and completed a preliminary design for a sand filter system.
