The oil separator isn’t very effective; try using an antifoam agent.

Is there no air flotation in the pretreatment? Find ways to increase the residence time in the hydrolysis tank, or determine which process generates wastewater with a high oil content; collect that oil as much as possible and add it evenly to the adjustment tank, rather than dumping it all at once into the adjustment tank.
