Wastewater treatment for the mining and metals industry is essential for environmentally responsible and compliant production processes. Steel mills and metal processing facilities generate large quantities of cooling water during steel production and processing. During production, this water collects mill scale from workpieces and can also become contaminated with fats and oils from conveying and transport equipment. Before the water can be reused as cooling water or discharged to the sewer system, the wastewater must be appropriately treated.

Wastewater Treatment for the Mining and Metals Industry with Sedimentation and Coagulation
OKO-tech uses the high specific gravity of mill scale particles to separate them efficiently through sedimentation in lamella clarifiers. Finely dispersed mill scale particles are agglomerated through coagulation, forming larger particles that can also be removed by sedimentation. This process removes solids from the wastewater and reduces the load on downstream water treatment systems.
Energy-Efficient Flotation for Fats and Oils
Wastewater from the mining and metals industry can also contain fats and oils that affect water quality and make water reuse more difficult. OKO-aquaclean Flotation Systems continuously and automatically separate these substances from the wastewater. The combination of flotation and mechanical solids separation produces treated water that can meet applicable requirements for indirect discharge and can, where suitable, be reused in cooling circuits.
Treatment Systems for Complex Wastewater Streams
As wastewater characteristics can vary significantly across the mining and metals industry, OKO-tech develops treatment systems based on the specific wastewater composition and process requirements. These systems combine sedimentation, coagulation and flotation according to the respective contaminant loads.
By combining different treatment processes, both metal-containing solids and oil- and fat-containing emulsions can be effectively separated from the wastewater stream. This supports stable wastewater management and the long-term reuse of treated water where appropriate.
