Steel manufacturing generates various wastewater streams requiring specialized treatment to remove oils, suspended solids, and dissolved metals.

Steel Industry Wastewater Streams

Rolling Mill Effluent

Contains rolling oils, iron oxide particles, and scale. High temperature possible.

Cooling Water Blowdown

High temperature, low contaminants but requires treatment before discharge or reuse.

Sanitary Wastewater

Municipal-type wastewater requiring standard treatment.

Stormwater Runoff

Contaminated with particulates, oils, and metals from yard areas.

Treatment Technologies

Oil-Water Separation

API separators and dissolved air flotation (DAF) for oil removal from rolling mill effluent.

Clarification

Tube settlers and clarifiers for suspended solids removal.

Filtration

Multi-media filtration and membrane systems for polishing to reuse standards.

Water Reuse in Steel Plants

• Cooling tower makeup
• Process water
• Rolling mill rinse water
• Slash and spray applications
