Both treatment systems incorporate Veolia’s Actiflo Turbo sand-ballasted clarification technology. The wastewater treatment system also includes Veolia’s AnoxKaldnes Moving Bed Bioreactor (MBBR) integrated with an activated sludge process for organics removal, and chemical conditioning using a 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. Total treatment capacity for the process water system is 14.4 million gallons per day (MGD).The 5.8-MGD wastewater treatment system will begin operation once steel production begins this summer.
John Hayden, construction coordinator at ThyssenKrupp Stainless USA, said: “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. NA Water Systems completed the design-build projects with value-added engineering and an exemplary safety record, on schedule and under the budget originally projected.”
