PITTSBURGH, PA - Veolia Water Solutions & Technologies announced today the completion of the river water intake and wastewater treatment projects at the ThyssenKrupp Stainless USA and ThyssenKrupp Steel USA mills in Calvert, AL. The water treatment systems were designed and built by N.A. Water Systems, a Veolia Water Solutions & Technologies (VWS) company located near Pittsburgh, PA, and will be operated by Veolia Water North America under a long-term contract.
"Today's announcement is a culmination of more than two years of extraordinary teamwork with Veolia Water, local contractors R.J. Baggett and Gulf Electric, and Crowder Construction," said ThyssenKrupp Stainless USA Construction Coordinator John Hayden. "The plant is designed with the latest technology to safeguard the environment and provide flexibility for future growth, and builds upon ThyssenKrupp's well-known commitment to sustainability. "N.A. Water Systems completed the design-build projects with value-added engineering and an exemplary safety record, on schedule and under the budget originally projected.
Both treatment systems incorporate VWS' patented ACTIFLO® Turbo sand-ballasted clarification technology. The wastewater treatment system also includes VWS' AnoxKaldnes™ Moving Bed Bioreactor (MBBR) integrated with an activated sludge process for organics removal, and chemical conditioning using an innovative TURBOMIX™ reactor for metals precipitation. These technologies enable the treatment processes to produce high-quality water within a very small footprint as compared to conventional systems.
The process water system is currently supplying water for commissioning of equipment for the new carbon steel and stainless steel facilities. When completed, the carbon steel operations will have a capacity of 4.3 million metric tons of carbon steel products. ThyssenKrupp plans to start up its hot strip mill this summer and ramp up to include cold rolling and galvanizing processes. The stainless steel operations will ultimately have a manufacturing capacity of 1 million metric tons of stainless steel products, beginning this fall with cold rolling and finishing processes, and later ramping up hot and cold forming operations and a melt shop. Total treatment capacity for the process water system is 14.4 million gallons per day (MGD).The 5.8-MGD wastewater treatment system also has been completed and will begin operation once steel production begins this summer.
