Steel Sludge Dewatering
SNF supports raw-water clarification, oily-water treatment, and sludge dewatering across steel plants.
Zone Introduction
Settling pits across steel plants generate large sludge volumes that must be dewatered efficiently to reduce disposal and recovery costs.
Process Description
Sludge includes hard metallic fines, mill scale, and mineral contaminants → very dense & abrasive.
Issues & Root Causes
- Hard solids → Filter media wear
- High water retention → Low dryness
- Large daily volume → Handling difficulty
Performance Loss & Compliance Impact
Heavy wet sludge increases transport fuel & disposal cost
Frequent filter press shutdown for cleaning
Poor solid recovery economics
