Advanced wastewater recovery system to be installed at OK rod mill

Sponsored by


BOSTON, MA, Nov. 7, 2013 -- Mid American Steel and Wire, a supplier in the wire and rod industry, will soon receive an advanced wastewater recovery system to reduce both the disposal costs and environmental impact of the operations at its rod mill at the Madill, Okla., facility.

Desalitech, a provider of high-efficiency water production and treatment solutions, will supply the wastewater recovery system which will recycle up to 60,000 gallons per day of wastewater for reuse in the mill. The integrated treatment solution will include pretreatment steps for removing contaminants and debris followed by reverse osmosis purification and is uniquely capable of achieving high recovery from a challenging wastewater created by steel manufacturing.

Water used in the cooling process of steel manufacturing becomes contaminated and must be recycled or disposed. Although Mid American has always recycled a substantial portion of process water to minimize the impact on the environment, it is necessary to purge water from their recycle tank on a daily basis to maintain proper chemistry in the facility's process water loop. Historically, wastewater has been hauled away for disposal at a significant cost.

The Desalitech system will treat the wastewater inside of the facility with the highest possible efficiency to maximize the yield of valuable recycled water, ensure its purity, reduce plant discharges and associated costs, and minimize environmental impact. Additionally, the recycled water will now have a constant quality that will aid in maintaining consistency within the operation of the rod mill. Improved yield is expected as excess scale can be avoided with a more consistent water quality.

Desalitech’s Closed Circuit Desalination (CCD™) solutions extract purified water from challenging and varying sources at high recovery rates with minimal energy consumption. The Mid American system will operate at up to 93 percent recovery, concentrating the plant's purge stream by a factor of 14 and dramatically decreasing the volume of wastewater produced by the facility.

About Desalitech

Desalitech provides resource and cost efficient water production and effluent treatment solutions. Its patented next-generation CCD™ process is a proven, highly flexible and low energy water treatment platform that represents the first major improvement in RO water treatment in decades. CCD systems lower costs by 20 to 60 percent by increasing water-use efficiency, reducing energy consumption, increasing flexibility and reliability and greatly reducing the emission of brine waste. With their unique capability of extracting purified water from challenging sources at high recovery rates, CCD products are ideal for industrial water and effluent treatment, agricultural water supply and inland brackish desalination.

About Mid American Steel & Wire

The Moore family began in the steel and wire industry in the early 1960’s by owning and operating Seymour Manufacturing in Seymour, Iowa. With expansion into wire panels, farm gates and grain stirring equipment, the company expanded further into Farm Equipment Manufacturing Company, which eventually became what is now Iowa Steel and Wire. In 1979, B. L. Moore and his brother-in-law, Robert Lockridge, founded Oklahoma Steel and Wire located in Madill, Oklahoma, with the sole purpose of manufacturing livestock panels. Both companies shared in steady expansion and soon included a comprehensive product line to agricultural and industrial markets. Today these two facilities produce in excess of 200,000 tons of steel per year and employ more than 400 people.
