Oil sludge is produced in the process of raw oil dehydrating in oil field corporations and oily sewage disposal in the petrochemical industry factories.

Use ICB technique and remove acid material in the fire resistant oil by adsorption instead of neutralization, so no water produced. Reduce the process of dehydrating.

Vacuum belt filter and belt press filter are the usual equipments of oil sludge dehydrating. But they have respective virtues and shortcomings.
