Prewash, Stripping and Demucking: Getting the Sequence Right

Order matters

Jumping straight to fine chemistry on a tank full of sludge wastes time and chemistry. A disciplined sequence keeps cycles predictable.

Typical flow

1. Stripping / drain — remove free liquid and pumpable residues
2. Demucking — clear compacted mud and heavy solids
3. Wash / HP-UHP — strip remaining films
4. Fine clean / verify — wall-wash or survey readiness
5. Waste handover — MARPOL-aligned disposal
