McKim & Creed utilized the design-build delivery project execution method to plan, design, oversee construction, and commission the domestic water and industrial wastewater treatment systems at a new tire manufacturing plant. The wastewater system process uses modular membrane bioreactors to treat water from several sources, including plant drains, ion exchange regenerants, condensate, backwash, and rinse water. The system removes both free and emulsified oil and grease, and produces water suitable for reuse in the tire production process, or water for fire protection systems at the facility. In addition, an accompanying sludge dewatering system provides a solid waste product suitable for disposal.
The water treatment process uses greensand pressure filtration to remove iron, manganese, and suspended solids from onsite well water. To the extent possible, both the water and wastewater systems are mounted on skids to reduce field labor and onsite installation and allow space for future infrastructure that may be required as the facility expands.
With these systems in place, not only are the tires safe, but the water and wastewater byproducts are as well.
