Canister partition tear hole
Thread Content
One of our company’s wastewater separation tanks has a partition in the middle that is used to separate the oil found in the upper layer of the wastewater to the other side of the partition. Why is there then a hole at the bottom of this partition? How can separation be achieved like this? There is no issue with pressure difference on either side of the partition

No, the water on both sides of the partition can be drained separately. What I mean is, with these tear holes, wouldn’t the water flow from those holes to the other side of the partition?
The main function of the tear hole is to drain any remaining liquid when stopping, so that no fluid remains on it, thereby preventing corrosion. The diameter of the lacrimal punctum is small, and under normal conditions, leakage does not occur due to the effect of the rising gas phase. This seems reasonable. I searched for it
Upstairs, this tank is a liquid-liquid separation tank! There is no rising vapor phase, only a residual vapor phase.
Block it when it’s working normally, and open it when the flow is cleared......
Equipment with a liquid phase separation layer should not have holes in the partition, otherwise the separation effect will not be achieved.
Why doesn’t it leak? Could some expert please explain this? I would be very grateful
So what if it leaks? The oil phase is on the upper layer and the water is on the lower layer; there’s no problem
Teardrop orifices are widely used on the liquid collection trays of tower equipment; they should also be used appropriately in other applications!
