7.1
Separation time
It is recommended that the oil volume (V) in the
complete system, not only the tank volume, is
separated at least five times. The separation
capacity will normally be adjusted to about 100
litres per hour. Calculate the minimum running
time (T) by using the adjacent formula.
NOTE
If separating emulsified oil it could be necessary to
separate the total volume up to 10 - 15 times.
T = (V x 5)/100
T = Minimum running time
V = Volume in complete system (in litres)
Formula for calculating minimum separation time
7.2
Separation mode
Introduction
To learn the correct running strategy, first read
the information below carefully before starting
the separation process.
1.
Decide if the separator will be operated as
clarifier or purifier. The difference between
them is described in chapter
5 Working
principle of the separator
.
At delivery the separator is assembled as
a clarifier.
2.
If the amount of water and sludge in the
oil is unknown, start the separation in
clarifier mode (change of operation mode
is described in chapter
5.4 Changing
operation mode on page 22
).
Run for 3 - 4 hours.
