A new Coupled Pickling/Cold Mill (CPCM) complex was recently commissioned at Dofasco. The complex produces oily, particulate bearing and acidic wastewaters which must be managed in an environmentally sound manner. Segregation of these streams within the mill and a new wastewater treatment plant satisfy this requirement. The design of the wastewater treatment plant was based on meeting current and anticipated government regulations, incorporating Best Available Technology, maximizing reuse/recycle and minimizing operating costs. The treatment plant was commissioned during 1992. While start-up took somewhat longer than expected and required a number of minor modifications, the plant has consistently met discharge criteria. The background investigation and design considerations for the treatment plant are examined. The plant layout and processing trains are reviewed. Commissioning and initial operating experience are also presented.
