Water Treatment Facilities
for New Alabama Mills
ThyssenKrupp Stainless USA and ThyssenKrupp Steel USA have completed the process water and wastewater treatment systems at their new facilities in Calvert, Ala. The systems were designed and built by N.A. Water Systems, a Veolia Water Solutions & Technologies company, which will operate them under a long-term outsourcing contract.
The process water system is currently operating for the commissioning of equipment for the new carbon steel and stainless steel facilities. The carbon steel operations are building to a manufacturing capacity of 4.3 million metric tons of carbon steel products, with plans to start up its hot-strip mill this summer and ramping up to include cold rolling and galvanizing processes. The stainless steel operations are building to a manufacturing capacity of 1 million metric tons of stainless steel products beginning this fall with cold- rolling and finishing processes, and a later ramp-up of hot- and cold-forming operations and a melt shop. Total treatment capacity for the process water is 14.4 million gallons per day. The 5.8-million-gallon capacity wastewater treatment system also has been completed and stands ready for operation once steel production begins this summer.
