Primary Metal Manufacturing

Rugged, cost-effective wastewater and process water treatment systems that boost the efficiency of metal production and processing facilities.

Metals (steel, aluminum) processing requires significant amounts of water for cooling, production and heat treating. These facilities produce process waters streams with high amounts of metals, oils & greases and other contaminants which are critical to address prior to recycling and reusing or discharging back into the environment.

Solutions

Our compact and efficient dissolved air flotation (DAF) technology excels in treating water streams with oils & greases, suspended solids and dissolved metals, meeting the requirements of processes such as:

Cooling water treatment
Caster spray water treatment
Rolling mill contact water treatment
Facility wastewater treatment
Raw water make-up systems

We designed our treatment systems to control pH and remove total suspended solids (TSS) and oils & greases from process water or wastewater streams. Highly effective at treating process water or wastewater in the metals industry, our Ideal DAF™ system includes the following key features:

Progressive water extraction to extend retention time and improve effluent quality
Plate separators to maximize solid contaminant removal
A cross-flow design to promote better separation with a lower fluid velocity

Case Studies

Railcar Bearing Manufacturer

A manufacturer of railcar bearings, wheels, and axles needed a wastewater system upgrade to treat for oil, grease, suspended solids, and dissolved metals in a mix of process water and storm water runoff.

Aluminum Casting Facility

The aluminum casting facility of a producer of semifabricated aluminum products utilizes a closed-loop contact water system that supplies water to multiple DC casting pits. An existing induced air flotation (IAF) system was used for the reduction of TSS, NTU, oil and grease, followed by a cooling tower.
