Blast Furnace / RMHS Wastewater
SNF supports raw-water clarification, oily-water treatment, and sludge dewatering across steel plants.
Zone Introduction
BF & RMHS operations generate wastewater with a mix of fine solids, coke breeze, scale, and oil from mechanical handling.
Process Description
Water used for material handling carries iron fines, lubricants, and hydrocarbons making treatment complex. Settling alone cannot remove emulsified oils.
Quality Issues & Root Causes
- Oil emulsions → Sticky sludge
- Magnetic fines → Slow settling
- Abrasive solids → Pump & pipe wear
Performance Loss & Compliance Impact
Oil film negatively affects reuse
Clarifier overflow may breach limits
Increased cleaning frequency of pits
