This water is drained into scale pits after use. Mills do not waste all of this water; it is recycled. Mill scales are sent to sintering plants for recycling to the blast furnace. Here, the water is filtered for further use. The overflow with the fine mill scale and oil is sent to a clarifier or a sand filter to eliminate any suspended solids.

Mill scale is a by-product of water jets cooling steel. A clarifier crane system separates mill scale from the water, collects it into piles, and removes the product for resale. Then, the remaining water is treated and rerouted for processes inside the steel mill. The system needed to be upgraded to keep this process running smoothly.

In steel production, hot milling and casting uses water at rates of between 100 m 3 /h and 10,000 m 3 /hr depending on the scale of the operation.

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
