SMS Wastewater (Steel Melting Shop)
SNF supports raw-water clarification, oily-water treatment, and sludge dewatering across steel plants.
Zone Introduction
SMS wastewater includes metal fines, slag particles, and scale from continuous casting and billet handling. Efficient removal is mandatory to prevent clogging and heat transfer loss.
Process Description
Direct contact water accumulates ultra-fine oxides & slag dust, forming stable suspensions requiring chemical enhancement.
Issues & Root Causes
- Extremely fine metallic particles → Poor settlement
- High load variability during heat cycles
- Slag impurities → Sticky sludge
Performance Loss & Compliance Impact
Nozzle & spray header clogging
Overloaded pits → Emergency shutdown risks
Lower cooling efficiency
