How to treat diesel and gasoline wastewater?
Thread Content
Our wastewater treatment plant has a regulating tank. Once, during a process of separating gasoline from water, the oily wastewater was discharged directly into this regulating tank. Since gasoline floats on the surface, the lift pumps were unable to transfer the oil to the air flotation unit, which created an unsightly situation. When the safety officers saw this, they considered it a hazard and asked us to remove the gasoline from there; I was very puzzled by this. I think a regulating tank is just a collection tank for oily wastewater – does it really have to be that clean? So, how should oil spills be dealt with? . .
Add an oil spill collector, and that’s it
It won’t cause a combustion explosion either; in my opinion, the level of danger is not high. As for how to remove oil, an oil strainer can be considered.
