Other Components:

Is the process a continuous operation or a batch operation?

Yes

No

How many hours per day are allocated to the separation process?

Solids in Suspension:

(choose those that apply)

Text

Does either liquid phase contain suspended solids before separation?

Yes

No

Are these solid particles soluble in the other liquid phase?

Yes

No

Can these particles be eliminated before introduction to the separator?

Yes

No

- Specify Method:

If the particles can be eliminated by centrifugal decantation, please specify:

- The centrifugal force

- Rotational speed

- Decanter bowl diameter

If there are no insoluble solids in the initial two phases, do any precipitates appear during the process of separation?

Yes

No

In this case, after separation, are these precipitates situated:

on the surface of the light phase

at the bottom of the heavy phase

at the interface of the two phases

within one of the phases

- if within one of the phases, specify which phase:

Special Characteristics of the Process:

Are the two phases easily mixed?

Yes

No

Does an emulsion appear when the two phases are vigorously stirred?

Yes

No

In the case of an emulsion:

If the phases separate by gravity, specify time required:

If the phases can only be separated by centrifugal decantation, please specify:

(if unknown, specify decanter bowl diameter and rotational speed)

total decantation time

centrifugal force

if unknown, specify decanter bowl diameter and rotational speed

Following centrifugal separation, is the interface between the two phases distinct?

Yes

No

Following centrifugal separation, does one of the two phases remain cloudy?

Yes

No

If Yes, which phase?

Is it possible to submit samples of each phase for hydraulic characterization tests?

Yes

No

Approximately 250 cc of each phase is sufficient.

Materials of Construction:
