What is the best method of oily sludge treatment?

Centrifuge processing scheme

For the treatment of oil pollution (waste) water, its purpose is to recover more oil, to reduce the oil content in the solid, so the role of each section in the whole process system is very important.

1. Demulsifier and surfactant can improve demulsification efficiency, improve subsequent separation efficiency, improve oil recovery and reduce the oil content in the slag phase.

2. Heating can reduce the viscosity of oil, improve oil recovery and reduce the solid content of oil and water.

3. Adding a PAM flocculant can improve the recovery rate of solids and reduce the content of solids in the liquid phase.

4. The use of high efficient LW series centrifuge, can improve the separation efficiency, improve oil recovery, and reduce the slag oil content.

5. Solid-liquid separation of water treatment using efficient LW series two-phase centrifuge, can reduce the liquid rate of slag phase, easy to transport, and improve the calorific value of combustion.

[Separation performance:

1, can recover about 70-85% of the oil (oil density, demulsification effect, temperature, etc.), the recovery of oil through the disc centrifuge further purification can be used for refining;

2. After centrifuge separation, the dryness of the slag phase can reach 40 ~ 60%, and the total volume is more than 80% less than before separation;
