A steel mill is perhaps the most significant industrial intersection of oil and water. The extensive use of water for cooling and descaling, alongside the significant volumes of hydraulic, lubricating, and cooling oils essential for steel production, constantly challenge and demonstrate the truth of the adage "oil and water do not mix."
Oil Contamination in Steel Mills Process Water
The production of steel is a resource-intensive process, especially when it comes to water usage. It can take anywhere from 10,000 to 75,000 gallons of water to produce one ton of steel, depending on how much of that water is recycled. This significant range underscores the importance of reusing water whenever possible to reduce operational costs. However, in order for water to be reused in most steel mill processes, it must be free of contaminants such as oils, which can severely impact the mill's ability to recycle water efficiently.
Tramp oils are a common contaminant in steel mill process water, and their presence can lead to a variety of operational problems. When water is tainted with oil, its effectiveness as a coolant or lubricant diminishes, reducing the efficiency of key processes. In addition, oil-contaminated water cannot be released into the facility’s wastewater system without causing environmental hazards. Stringent environmental regulations often prevent the discharge of such contaminated water, and failure to comply with these regulations can lead to fines and increased operational challenges for the mill.
Furthermore, the presence of oils in process water can create an ideal environment for bacterial growth. This poses a significant health risk to workers and can further compromise the quality of the recycled water. If water cannot be adequately treated for reuse due to contamination, it leads to higher production costs as the mill is forced to rely on fresh water supplies. Ensuring water purity through effective contamination control is not only critical for reducing costs but also for maintaining safe working conditions and complying with environmental standards.
Abanaki Model 8 Oil Skimmer
What strategies can be implemented at a steel mill to prevent or reduce oil contamination in process water? One effective option is the Abanaki Model 8 Belt Oil Skimmer, which provides a reliable solution for extracting oil from water and water-based solutions commonly used in mills. This oil skimming technology leverages the differences in specific gravity and surface tension between oil and water, enabling the belt skimmer to draw in oil and other hydrocarbon liquids from the fluid's surface.
The Model 8 has the capability to reduce oil content in water to less than five parts per million, depending on the liquid's characteristics. It operates using a continuous belt and wiper system, effectively removing up to 40 gallons of oil per hour from the surface of the fluid. This unit can serve as a pre-treatment step before filtration and can be used in conjunction with coalescing systems for enhanced efficiency. Its versatility extends beyond steel mills, making the Model 8 suitable for a variety of applications, including:
