Gravity Disk in Purifier alters the location of the oil-water interface and is responsible for creating an interface between the oil and water.
And further, the Interface can be shifted inwards or outwards with the correct selection of the gravity disk in your purifier. And With the proper selection of the gravity disk, the efficiency of the separation can also be improved.
The gravity disc with proper inner diameter i.e. with the diameter that corresponds to the difference in densities of the oil-water mixture to be treated should, therefore, be inserted in the bowl, This disc can be chosen from the set of discs provided with the separator.
The inner diameter of the disc to be chosen can be determined by: Calculation ExperimentThe general rule is : Small diameter gravity disc when treating heavy oilLarge diameter regulating ring when treating light oil
