Difficult oily sludges require specialized treatment to separate oil, water and suspended solids. These sludges arise from natural settlement and from primary treatment of oil emulsions.
After removal of separated oil, the remaining sludge may require further treatment to complete separation of remaining oil and solids from the water phase.
KEY PROPERTIES
Demulsifiers are designed to separate emulsions into three phases:-
| Oil Phase |
− for recycling |
| Water Phase |
− for discharge to foul drain under a normal industrial consent |
| Solids |
− for disposal to land fill as non-hazardous waste |

APPLICATION
Typical doses vary widely and should be tested preferably on actual material before full treatment is attempted.
If the water content of the sludge is low, consider adding more water to mix to aid separation of the oil and solids.
Use WT 620 typically at 1000 to 1500ppm, mix with the sludge for 5 minutes and then treat with OS 88 at up to 3000ppm.
Leave the sludge to separate.
At this stage very slow agitation can assist complete separation.
Fast stirring or pumped circulation is not recommended.
Viscous sludges will often separate after chemical treatment at ambient temperature.
When the oil content in the sludge is high viscosity, heating may be required.
