TREATING AND REUSING WASTEWATER AT MID AMERICAN STEEL

“Hauling wastewater for disposal by truck was a major cost center and we sought a solution that would reduce those costs through higher recovery. Desalitech system’s paid for itself with-in two months while improving the quality of water in the plant’s recycle loop. The value proposition is compelling, not only because of reduced costs but also because of reduced environmental impact.”

Industry:
Steel & Wire Manufacturing

Application:
Wastewater Reuse and near Zero Liquid Discharge

Products Used:
Multimedia and Granular Activated Carbon Pretreatment
ReFlex System

Year Completed:
2014

Client:
Mid America Steel & Wire

Project Size:
50 gallons per minute permeate

Challenge:
Mid America Steel located in Madill Oklahoma requires water for cooling steel and tools in its manufacturing process. Water used for cooling becomes contaminated with metals and lubricants and was therefore being disposed of as waste. Over 60,000 gallons of wastewater was being hauled offsite for disposal, costing over $10,000 per day or $3,000,000 per year. Along with a goal to reduce operating costs, the steel mill also had a sustainability goal that called for reducing environmental footprint.

Solution:
Mid American Steel installed a Desalitech ReFlex Reverse Osmosis system to treat and recycle its waste water. The ReFlex system operates at maximum efficiency, reducing the mill’s consumption of fresh water and reducing wastewater generation by 93%. The ReFlex system also ensures high product water purity, improving cooling performance and consistency within the operation of the rod mill. In addition to water savings, the low energy consumption of the ReFlex system helps minimize environmental impact. As anticipated, the return on investment for installing the system was less than two months.

Results:
Water Savings
– Recovery operating steadily at over 93%

Reduced Environmental Footprint
– A new source of water was created

Waste Removal Savings
– Savings of $10,000 and 60,000 gallons per day

Quick Payback
– Less than 2 month return on investment
