The only ,way, to remove the remaining dissolved oil is thru biological treatment. This and the remaining steps are the same as those found in a normal wastewater treatment facility. Many components in the process must be in balance in order to obtain complete synergy such as, biomass blends, air, return activated ,sludge, (RAS), waste activated ,sludge, (WAS) and throughput.

The ‘bound water’ content of sewage ,sludge, is 90-98%. When ,sludge, is heated under pressure at temperatures of 175-200°C in a wet air oxidation system, the gel like structure of the ,sludge, is destroyed, liberating the bound water. Dewatering by filtration, centrifugation or drainage beds without chemical conditioning is then possible.

4% ,oily sludge, is recommended ,to treat, the subgrade, with which an increase in strength of approximately 37% compared to the natural subgrade is achieved. Given the results of the CBR and resilient modulus tests and taking into account the conditions under which the specimens were tested, the importance of curing the mixtures to gain strength over time is noted.

For most ,oily sludge,, the trickiest part ,to treat, is usually in the form of an oil–inorganic mixture. In this kind of mixture, oil exists as an oil-in-water emulsion, and the oil is tightly bound to inorganic components. In addition, FOS contains a large amount of these types of mixtures, so it is harder to achieve oil separation.
